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.
