Run a command with a different root directory
''chroot'' runs a command with a specified root directory. On many systems, only the super-user can do this.
chroot NEWROOT [COMMAND [ARGS]...]
chroot OPTIONOrdinarily, filenames are looked up starting at the root of the directory structure, i.e. ''/''
''chroot'' changes the root to the directory NEWROOT (which must exist) and then runs COMMAND with optional ARGS.
If COMMAND is not specified, the default is the value of the `SHELL'' environment variable or `/bin/sh'' if not set, invoked with the `-i'' option.
The only options are `--help'' and `--version''
