chroot

chroot [OPTION]... NEWROOT [COMMAND [ARG]...]

Run COMMAND with root directory set to NEWROOT.

Options

--user=<USER>, -u <USER>

User (ID or name) to switch before running the program

--group=<GROUP>, -g <GROUP>

Group (ID or name) to switch to

--groups=<GROUP1,GROUP2...>, -G <GROUP1,GROUP2...>

Comma-separated list of groups to switch to

--userspec=<USER:GROUP>

Colon-separated user and group to switch to. Same as -u USER -g GROUP. Userspec has higher preference than -u and/or -g

--skip-chdir

Use this option to not change the working directory to / after changing the root directory to newroot, i.e., inside the chroot.

Examples

Run command as new root directory:

chroot {{path/to/new/root}} {{command}}

Use a specific user and group:

chroot --userspec={{username_or_id:group_name_or_id}}
