NAME
       profile - Security profile file syntax for Firejail

USAGE
       firejail --profile=filename.profile
       firejail --profile=profile_name

DESCRIPTION
       Several command line options can be passed to the program using profile
       files. Firejail chooses the profile file as follows:

       1. If a profile file is provided by the user with --profile option, the
       profile  file is loaded. If a profile name is given, it is searched for
       first in the ~/.config/firejail directory and  if  not  found  then  in
       /etc/firejail directory. Profile names do not include the .profile suf‐
       fix.  Example:

              $ firejail --profile=/home/netblue/icecat.profile icecat
              Reading profile /home/netblue/icecat.profile
              [...]

              $ firejail --profile=icecat icecat-wrapper.sh
              Reading profile /etc/firejail/icecat.profile
              [...]

       2. If a profile file with the same name as the application  is  present
       in  ~/.config/firejail  directory  or  in /etc/firejail, the profile is
       loaded. ~/.config/firejail takes precedence over  /etc/firejail.  Exam‐
       ple:

              $ firejail icecat
              Command name #icecat#
              Found icecat profile in /home/netblue/.config/firejail directory
              Reading profile /home/netblue/.config/firejail/icecat.profile
              [...]

       3.  Use  a  default.profile file if the sandbox is started by a regular
       user, or a server.profile file if the sandbox is started by root. Fire‐
       jail looks for these files in ~/.config/firejail directory, followed by
       /etc/firejail directory.  To disable default profile loading, use --no‐
       profile command option. Example:

              $ firejail
              Reading profile /etc/firejail/default.profile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]

              $ firejail --noprofile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]

Templates
       In  /usr/share/doc/firejail  there  are two templates to write new pro‐
       files.
              profile.template - for regular profiles
              redirect_alias-profile.template - for aliasing/redirecting  pro‐
              files

Scripting
       Scripting commands:

       File and directory names
              File  and  directory  names containing spaces are supported. The
              space character ' ' should not be escaped.

              Example: "blacklist ~/My Virtual Machines"

       # this is a comment

       ?CONDITIONAL: profile line
              Conditionally add profile line.

              Example: "?HAS_APPIMAGE: whitelist ${HOME}/special/appimage/dir"

              This example will load the whitelist profile line  only  if  the
              --appimage option has been specified on the command line.

              Currently  the  only conditionals supported this way are HAS_AP‐
              PIMAGE, HAS_NET, HAS_NODBUS, HAS_NOSOUND and HAS_X11. The condi‐
              tionals BROWSER_DISABLE_U2F and BROWSER_ALLOW_DRM can be enabled
              or disabled globally in Firejail's configuration file.

              The profile line may be any profile line that you would normally
              use in a profile except for "quiet" and "include" lines.

       include other.profile
              Include other.profile file.

              Example: "include /etc/firejail/disable-common.inc"

              The  file  name  can be prefixed with a macro such as ${HOME} or
              ${CFG}.  ${HOME} is expanded as user home directory, and  ${CFG}
              is expanded as Firejail system configuration directory - in most
              cases /etc/firejail or /usr/local/etc/firejail.

              Example:   "include   ${HOME}/myprofiles/profile1"   will   load
              "~/myprofiles/profile1" file.

              Example:  "include ${CFG}/firefox.profile" will load "/etc/fire‐
              jail/firefox.profile" file.

              The file name may also be just the name without the leading  di‐
              rectory  components.  In this case, first the user config direc‐
              tory (${HOME}/.config/firejail) is searched for  the  file  name
              and  if  not  found  then  the system configuration directory is
              search for the file name.  Note:  Unlike  the  --profile  option
              which  takes  a  profile name without the '.profile' suffix, in‐
              clude must be given the full file name.

              Example:  "include  firefox.profile"  will  load  "${HOME}/.con‐
              fig/firejail/firefox.profile"  file  and  if  it  does not exist
              "${CFG}/firefox.profile" will be loaded.

              System configuration files  in  ${CFG}  are  overwritten  during
              software installation.  Persistent configuration at system level
              is handled in ".local" files. For every profile file  in  ${CFG}
              directory, the user can create a corresponding .local file stor‐
              ing modifications to the  persistent  configuration.  Persistent
              .local files are included at the start of regular profile files.

       noblacklist file_name
              If  the file name matches file_name, the file will not be black‐
              listed in any blacklist commands that follow.

              Example: "noblacklist ${HOME}/.mozilla"

       nowhitelist file_name
              If the file  name  matches  file_name,  the  file  will  not  be
              whitelisted in any whitelist commands that follow.

              Example: "nowhitelist ~/.config"

       ignore Ignore command.

              Example: "ignore seccomp"
              Example: "ignore net eth0"

       quiet  Disable  Firejail's output. This should be the first uncommented
              command in the profile file.

              Example: "quiet"

Filesystem
       These profile entries define a chroot filesystem built on  top  of  the
       existing  host filesystem. Each line describes a file/directory that is
       inaccessible (blacklist), a read-only file or directory (read-only),  a
       tmpfs  mounted on top of an existing directory (tmpfs), or mount-bind a
       directory or file on top of another directory or file (bind).  Use pri‐
       vate  to  set  private  mode.  File globbing is supported, and PATH and
       HOME directories are searched, see the firejail FILE  GLOBBING  section
       for more details.  Examples:

       blacklist file_or_directory
              Blacklist directory or file. Examples:

              blacklist /usr/bin
              blacklist /usr/bin/gcc*
              blacklist ${PATH}/ifconfig
              blacklist ${HOME}/.ssh

       blacklist-nolog file_or_directory
              When  --tracelog flag is set, blacklisting generates syslog mes‐
              sages if the sandbox tries to  access  the  file  or  directory.
              blacklist-nolog  command  disables syslog messages for this par‐
              ticular file or directory. Examples:

              blacklist-nolog /usr/bin
              blacklist-nolog /usr/bin/gcc*

       bind directory1,directory2
              Mount-bind directory1 on top of directory2. This option is  only
              available when running as root.

       bind file1,file2
              Mount-bind  file1 on top of file2. This option is only available
              when running as root.

       disable-mnt
              Disable /mnt, /media, /run/mount and /run/media access.

       keep-dev-shm
              /dev/shm directory is untouched (even with private-dev).

       keep-var-tmp
              /var/tmp directory is untouched.

       mkdir directory
              Create  a  directory  in  user  home,  under  /tmp,   or   under
              /run/user/ before the sandbox is started.  The directory is
              created if it doesn't already exist.

              Use this command for whitelisted directories you  need  to  pre‐
              serve  when  the  sandbox is closed. Without it, the application
              will create the directory, and the  directory  will  be  deleted
              when  the sandbox is closed. Subdirectories are recursively cre‐
              ated. Example from firefox profile:

              mkdir ~/.mozilla
              whitelist ~/.mozilla
              mkdir ~/.cache/mozilla/firefox
              whitelist ~/.cache/mozilla/firefox

              For files in /run/user/ use ${RUNUSER} macro:

              mkdir ${RUNUSER}/firejail-testing

       mkfile file
              Similar to mkdir, this command creates an  empty  file  in  user
              home,  or  /tmp,  or under /run/user/ before the sandbox is
              started. The file is created if it doesn't already exist.

       noexec file_or_directory
              Remount the file or the directory noexec, nodev and nosuid.

       overlay
              Mount  a  filesystem  overlay  on top of the current filesystem.
              The overlay is stored in $HOME/.firejail/  directory.

       overlay-named name
              Mount  a  filesystem  overlay  on top of the current filesystem.
              The overlay is stored in $HOME/.firejail/name  directory.

       overlay-tmpfs
              Mount  a  filesystem  overlay  on top of the current filesystem.
              All  filesystem  modifications are discarded when the sandbox is
              closed.

       private
              Mount new /root and /home/user directories in temporary filesys‐
              tems.  All  modifications  are  discarded  when  the  sandbox is
              closed.

       private directory
              Use directory as user home.

       private-bin file,file
              Build a new /bin in a temporary filesystem, and  copy  the  pro‐
              grams  in  the list.  The files in the list must be expressed as
              relative to the /bin, /sbin, /usr/bin,  /usr/sbin,  or  /usr/lo‐
              cal/bin  directories.   The  same directory is also bind-mounted
              over /sbin, /usr/bin and /usr/sbin.

       private-cache
              Mount an empty temporary filesystem on top of the .cache  direc‐
              tory  in  user  home.  All  modifications are discarded when the
              sandbox is closed.

       private-cwd
              Set working directory inside jail to  the  home  directory,  and
              failing that, the root directory.

       private-cwd directory
              Set working directory inside the jail.

       private-dev
              Create  a new /dev directory. Only disc, dri, dvb, hidraw, null,
              full, zero, tty, pts, ptmx, random, snd,  urandom,  video,  log,
              shm and usb devices are available.  Use the options no3d, nodvd,
              nosound, notv, nou2f and novideo for additional restrictions.

       private-etc file,directory
              Build a new /etc in a temporary filesystem, and copy  the  files
              and  directories  in the list.  The files and directories in the
              list must be expressed as relative to the /etc  directory.   All
              modifications are discarded when the sandbox is closed.

       private-home file,directory
              Build  a  new  user home in a temporary filesystem, and copy the
              files and directories in the list in the new  home.   The  files
              and directories in the list must be expressed as relative to the
              current user's home directory.  All modifications are  discarded
              when the sandbox is closed.

       private-lib file,directory
              Build  a  new /lib directory and bring in the libraries required
              by the application to run.  The files  and  directories  in  the
              list  must be expressed as relative to the /lib directory.  This
              feature is still under development, see man 1 firejail for  some
              examples.

       private-opt file,directory
              Build  a  new /opt in a temporary filesystem, and copy the files
              and directories in the list.  The files and directories  in  the
              list  must  be expressed as relative to the /opt directory.  All
              modifications are discarded when the sandbox is closed.

       private-srv file,directory
              Build a new /srv in a temporary filesystem, and copy  the  files
              and  directories  in the list.  The files and directories in the
              list must be expressed as relative to the /srv  directory.   All
              modifications are discarded when the sandbox is closed.

       private-tmp
              Mount  an  empty  temporary  filesystem on top of /tmp directory
              whitelisting /tmp/.X11-unix.

       read-only file_or_directory
              Make directory or file read-only.

       read-write file_or_directory
              Make directory or file read-write.

       tmpfs directory
              Mount an empty tmpfs filesystem on top of directory. This option
              is available only when running the sandbox as root.

       tracelog
              Blacklist violations logged to syslog.

       whitelist file_or_directory
              Whitelist  directory or file. A temporary file system is mounted
              on the top directory, and the whitelisted files are mount-binded
              inside.  Modifications  to whitelisted files are persistent, ev‐
              erything else is discarded when the sandbox is closed.  The  top
              directory  could  be  user home, /dev, /etc, /media, /mnt, /opt,
              /srv, /sys/module, /usr/share, /var, and /tmp.

              Symbolic link handling: with the exception of  user  home,  both
              the  link and the real file should be in the same top directory.
              For user home, both the link and the real file should  be  owned
              by the user.

       writable-etc
              Mount /etc directory read-write.

       writable-run-user
              Disable  the  default  blacklisting of run/user/$UID/systemd and
              /run/user/$UID/gnupg.

       writable-var
              Mount /var directory read-write.

       writable-var-log
              Use the real /var/log directory, not  a  clone.  By  default,  a
              tmpfs  is  mounted  on top of /var/log directory, and a skeleton
              filesystem is created based on the original /var/log.

Security filters
       The following security filters are currently implemented:

       allow-debuggers
              Allow tools such  as  strace  and  gdb  inside  the  sandbox  by
              whitelisting system calls ptrace and process_vm_readv.

       apparmor
              Enable AppArmor confinement.

       caps   Enable default Linux capabilities filter.

       caps.drop capability,capability,capability
              Blacklist given Linux capabilities.

       caps.drop all
              Blacklist all Linux capabilities.

       caps.keep capability,capability,capability
              Whitelist given Linux capabilities.

       memory-deny-write-execute
              Install a seccomp filter to block attempts to create memory map‐
              pings that are both writable and executable, to change  mappings
              to be executable or to create executable shared memory.

       nonewprivs
              Sets  the NO_NEW_PRIVS prctl.  This ensures that child processes
              cannot acquire new privileges using execve(2);   in  particular,
              this means that calling a suid binary (or one with file capabil‐
              ities) does not result in an increase of privilege.

       noroot Use this command  to enable an user namespace. The namespace has
              only  one user, the current user.  There is no root account (uid
              0) defined in the namespace.

       protocol protocol1,protocol2,protocol3
              Enable protocol filter. The  filter  is  based  on  seccomp  and
              checks the first argument to socket system call. Recognized val‐
              ues: unix, inet, inet6, netlink and packet.

       seccomp
              Enable seccomp filter and blacklist the syscalls in the  default
              list. See man 1 firejail for more details.

       seccomp.32
              Enable  seccomp filter and blacklist the syscalls in the default
              list for 32 bit system calls on a 64 bit architecture system.

       seccomp syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in the list
              on top of default seccomp filter.

       seccomp.32 syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in the list
              on top of default seccomp filter for 32 bit system calls on a 64
              bit architecture system.

       seccomp.block-secondary
              Enable  seccomp  filter  and filter system call architectures so
              that only the native architecture is allowed.

       seccomp.drop syscall,syscall,syscall
              Enable seccomp filter and blacklist  the  system  calls  in  the
              list.

       seccomp.32.drop syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in the list
              for 32 bit system calls on a 64 bit architecture system.

       seccomp.keep syscall,syscall,syscall
              Enable seccomp filter and whitelist  the  system  calls  in  the
              list.

       seccomp.32.keep syscall,syscall,syscall
              Enable seccomp filter and whitelist the system calls in the list
              for 32 bit system calls on a 64 bit architecture system.

       seccomp-error-action kill | log | ERRNO
              Return a different error instead of EPERM to the  process,  kill
              it when an attempt is made to call a blocked system call, or al‐
              low but log the attempt.  #ifdef HAVE_X11

       x11    Enable X11 sandboxing.

       x11 none
              Blacklist /tmp/.X11-unix directory, ${HOME}/.Xauthority and file
              specified in ${XAUTHORITY} environment variable.  Remove DISPLAY
              and XAUTHORITY environment variables.  Stop with  error  message
              if X11 abstract socket will be accessible in jail.

       x11 xephyr
              Enable X11 sandboxing with Xephyr server.

       x11 xorg
              Enable X11 sandboxing with X11 security extension.

       x11 xpra
              Enable X11 sandboxing with Xpra server.

       x11 xvfb
              Enable X11 sandboxing with Xvfb server.

       xephyr-screen WIDTHxHEIGHT
              Set  screen size for x11 xephyr. This command should be included
              in the profile file before x11 xephyr command.

              Example:

              xephyr-screen 640x480
              x11 xephyr

DBus filtering
       Access to the session and system DBus UNIX sockets can be allowed, fil‐
       tered  or disabled. To disable the abstract sockets (and force applica‐
       tions to use the filtered UNIX socket) you would need to request a  new
       network namespace using --net command. Another option is to remove unix
       from the --protocol set.

       Filtering requires installing the xdg-dbus-proxy utility. Filter  rules
       can  be  specified  for well-known DBus names, but they are also propa‐
       gated to the owning unique name, too. The permissions are "sticky"  and
       are  kept  even  if the corresponding well-known name is released (how‐
       ever, applications rarely release well-known names in practice).  Names
       may  have  a  .*  suffix  to match all names underneath them, including
       themselves  (e.g.  "foo.bar.*"  matches  "foo.bar",  "foo.bar.baz"  and
       "foo.bar.baz.quux",  but  not "foobar"). For more information, see xdg-
       dbus-proxy(1).

       Examples:

       dbus-system filter
              Enable filtered access to the system DBus. Filters can be speci‐
              fied with the dbus-system.talk and dbus-system.own commands.

       dbus-system none
              Disable  access  to the system DBus. Once access is disabled, it
              cannot be relaxed to filtering.

              interface org.freedesktop.Notifications of the object exposed at
              the path /org/freedesktop/Notifications by the client owning the
              bus name org.freedesktop.Notifications on the system DBus.

       dbus-user filter
              Enable filtered access to the session DBus. Filters can be spec‐
              ified with the dbus-user.talk and dbus-user.own commands.

       dbus-user none
              Disable access to the session DBus. Once access is disabled,  it
              cannot be relaxed to filtering.

       dbus-user.own org.gnome.ghex.*
              Allow  the  application  to  own the name org.gnome.ghex and all
              names underneath in on the session DBus.

       dbus-user.talk org.freedesktop.Notifications
              Allow the application to talk to the name  org.freedesktop.Noti‐
              fications on the session DBus.

       dbus-user.see org.freedesktop.Notifications
              Allow   the  application  to  see  but  not  talk  to  the  name

              /org/freedesktop/Notifications by the client owning the bus name
              org.freedesktop.Notifications on the session DBus.

       dbus-user.broadcast org.freedesktop.Notifications=org.freedesktop.Noti‐
       fications.*@/org/freedesktop/Notifications

              interface org.freedesktop.Notifications of the object exposed at
              the path /org/freedesktop/Notifications by the client owning the
              bus name org.freedesktop.Notifications on the session DBus.

       nodbus (deprecated)
              Disable D-Bus access (both system and session buses). Equivalent
              to dbus-system none and dbus-user none.

       Individual  filters can be overridden via the --ignore command. Suppos‐
       ing a profile has
              [...]
              dbus-user filter
              dbus-user.own org.mozilla.firefox.*
              dbus-user.talk org.freedesktop.Notifications
              dbus-system none
              [...]

              and the  user  wants  to  disable  notifications,  this  can  be
              achieved by putting the below in a local override file:
              [...]
              ignore dbus-user.talk org.freedesktop.Notifications
              [...]

Resource limits, CPU affinity, Control Groups
       These  profile  entries define the limits on system resources (rlimits)
       for the processes inside the sandbox.  The limits can be  modified  in‐
       side  the sandbox using the regular ulimit command. cpu command config‐
       ures the CPU cores available, and cgroup command place the  sandbox  in
       an existing control group.

       Examples:

       cgroup /sys/fs/cgroup/g1/tasks
              The sandbox is placed in g1 control group.

       cpu 0,1,2
              Use only CPU cores 0, 1 and 2.

       nice -5
              Set a nice value of -5 to all processes running inside the sand‐
              box.

       rlimit-as 123456789012
              Set  the  maximum  size  of  the  process's  virtual  memory  to
              123456789012 bytes.

       rlimit-cpu 123
              Set the maximum CPU time in seconds.

       rlimit-fsize 1024
              Set  the  maximum  file size that can be created by a process to
              1024 bytes.

       rlimit-nproc 1000
              Set the maximum number of processes that can be created for  the
              real user ID of the calling process to 1000.

       rlimit-nofile 500
              Set  the maximum number of files that can be opened by a process
              to 500.

       rlimit-sigpending 200
              Set the maximum number of processes that can be created for  the
              real user ID of the calling process to 200.

       timeout hh:mm:ss
              Kill  the  sandbox automatically after the time has elapsed. The
              time is specified in hours/minutes/seconds format.

User Environment
       allusers
              All user home directories are visible inside the sandbox. By de‐
              fault, only current user home directory is visible.

       env name=value
              Set environment variable. Examples:

              env LD_LIBRARY_PATH=/opt/test/lib
              env CFLAGS="-W -Wall -Werror"

       ipc-namespace
              Enable IPC namespace.

              as remote pulse servers or non-standard socket paths.

       nodvd  Disable DVD and audio CD devices.

       nogroups

       notv   Disable DVB (Digital Video Broadcasting) TV devices.

       nou2f  Disable U2F devices.

       novideo
              Disable video devices.

       shell none
              Run the program directly, without a shell.

Networking
       Networking features available in profile files.

       defaultgw address
              Use this address as default gateway in  the  new  network  name‐
              space.

       dns address
              Set a DNS server for the sandbox. Up to three DNS servers can be
              defined.

       hostname name
              Set a hostname for the sandbox.

       hosts-file file
              Use file as /etc/hosts.

       ip address
              Assign IP addresses to the last network interface defined  by  a
              net command. A default gateway is assigned by default.

              Example:
              net eth0
              ip 10.10.20.56

       ip none
              No IP address and no default gateway are configured for the last
              interface defined by a net command. Use this option in case  you
              intend to start an external DHCP client in the sandbox.

              Example:
              net eth0
              ip none

       ip dhcp
              Acquire an IP address and default gateway for the last interface
              defined by a net command, as well as set the DNS servers accord‐
              ing  to  the  DHCP  response.   This  command  requires  the ISC
              dhclient DHCP client to be installed and will start it automati‐
              cally inside the sandbox.

              Example:
              net br0
              ip dhcp

              This command should not be used in conjunction with the dns com‐
              mand if the DHCP server is set to configure DNS servers for  the
              clients,  because  the  manually  specified  DNS servers will be
              overwritten.

              The DHCP client will NOT release the DHCP lease when the sandbox
              terminates.   If  your DHCP server requires leases to be explic‐
              itly released, consider running a DHCP client and releasing  the
              lease manually in conjunction with the net none command.

       ip6 address
              Assign IPv6 addresses to the last network interface defined by a
              net command.

              Example:
              net eth0
              ip6 2001:0db8:0:f101::1/64

       ip6 dhcp
              Acquire an IPv6 address and default gateway for the last  inter‐
              face  defined  by  a net command, as well as set the DNS servers
              according to the DHCP response.  This command requires  the  ISC
              dhclient DHCP client to be installed and will start it automati‐
              cally inside the sandbox.

              Example:
              net br0
              ip6 dhcp

              This command should not be used in conjunction with the dns com‐
              mand  if the DHCP server is set to configure DNS servers for the
              clients, because the manually  specified  DNS  servers  will  be
              overwritten.

              The DHCP client will NOT release the DHCP lease when the sandbox
              terminates.  If your DHCP server requires leases to  be  explic‐
              itly  released, consider running a DHCP client and releasing the
              lease manually.

       iprange address,address
              Assign  an  IP address in the provided range to the last network
              interface  defined  by  a  net command.  A  default  gateway  is
              assigned by default.

              Example:

              net eth0
              iprange 192.168.1.150,192.168.1.160

       mac address
              Assign MAC addresses to the last network interface defined by  a
              net command.

       machine-id
              Spoof  id  number  in  /etc/machine-id file - a new random id is
              generated inside the sandbox.

       mtu number
              Assign a MTU value to the last network interface  defined  by  a
              net command.

       net bridge_interface
              Enable a new network namespace and connect it to this bridge in‐
              terface.  Unless specified with option --ip and --defaultgw,  an
              IP  address and a default gateway will be assigned automatically
              to the sandbox. The IP address is verified using ARP before  as‐
              signment.  The  address  configured  as  default  gateway is the
              bridge device IP address. Up to four --net bridge devices can be
              defined. Mixing bridge and macvlan devices is allowed.

       net ethernet_interface|wireless_interface
              Enable  a  new network namespace and connect it to this ethernet
              interface using the standard Linux macvlan or ipvlan driver. Un‐
              less  specified  with option --ip and --defaultgw, an IP address
              and a default gateway will  be  assigned  automatically  to  the
              sandbox. The IP address is verified using ARP before assignment.
              The address configured as default gateway is the default gateway
              of  the  host.  Up  to four --net devices can be defined. Mixing
              bridge and macvlan devices is allowed.

       net none
              Enable a new, unconnected network namespace. The only  interface
              available in the new namespace is a new loopback interface (lo).
              Use this option to deny network access to  programs  that  don't
              really need network access.

       net tap_interface
              Enable  a  new network namespace and connect it to this ethernet
              tap interface using the standard Linux macvlan driver.   If  the
              tap  interface  is  not  configured, the sandbox will not try to
              configure the interface inside the sandbox.  Please use ip, net‐
              mask and defaultgw to specify the configuration.

       netfilter
              If  a  new network namespace is created, enabled default network
              filter.

       netfilter filename
              If a new network namespace is created, enabled the network  fil‐
              ter in filename.

       netmask address
              Use  this  option when you want to assign an IP address in a new
              namespace and the parent interface specified  by  --net  is  not
              configured.  An  IP  address  and a default gateway address also
              have to be added.

       veth-name name
              Use this name for the interface  connected  to  the  bridge  for
              --net=bridge_interface commands, instead of the default one.

Other
       deterministic-exit-code
              Always exit firejail with the first child's exit status. The de‐
              fault behavior is to use the exit status of the final  child  to
              exit, which can be nondeterministic.

       join-or-start sandboxname
              Join the sandbox identified by name or start a new one.  Same as
              "firejail --join=sandboxname" command if sandbox with  specified
              name exists, otherwise same as "name sandboxname".
