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.
