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