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.
