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.
