NAME

       chrootuid - run command in restricted environment

SYNOPSIS

       chrootuid [-i] newroot newuser command...

DESCRIPTION

       The  chrootuid  command  sets up a restricted environment for executing command. Access to
       the file system is restricted to the newroot subtree; privileges are restricted  to  those
       of  the  newuser  account (which must be a known account in the unrestricted environment).
       The initial working directory is changed to newroot.

       chrootuid combines chroot(8) and su(1) into one program, so that there is no need to  have
       commands such as /usr/bin/su in the restricted environment.

       Only the superuser can use the chrootuid command.

OPTIONS

       There  is only one option for chrootuid: -i. That option makes it run in interactive mode.
       Errors will be printed on stderr instead of through syslog and the exit status will  be  1
       if there are any errors.

RETURN CODES

       The exit status of chrootuid when running on daemon mode (default) is always 0.

       If  it  is  running on interactive mode, it will exit with an exit status of 1 if there is
       any error in its invocation, otherwise the exit status is the exit status of command.

DIAGNOSTICS

       Problems are reported to the syslog daemon if running  on  daemon  mode.   If  running  on
       interactive mode, errors are reported on stderr.
