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.
