ISCHROOT(1)                 General Commands Manual                ISCHROOT(1)

NAME
       ischroot - detect if running in a chroot

SYNOPSIS
       ischroot [--default-false] [--default-true] [--help] [--version]

DESCRIPTION
       ischroot  detects if it is currently running in a chroot. The exit sta-
       tus is:

       0      if currently running in a chroot

       1      if currently not running in a chroot

       2      if the detection is not possible (On GNU/Linux this  happens  if
              the script is not run as root).

OPTIONS
       -f, --default-false
              Exit with status 1 if the detection is not possible.

       -t, --default-true
              Exit with status 0 if the detection is not possible.

       --help Print a usage message on standard output and exit successfully.

       --version
              Print  version  information on standard output and exit success-
              fully.

BUGS
       On GNU/Linux, chroot detection is not  possible  when  not  root.  This
       works correctly on GNU/Hurd and GNU/kFreeBSD.
