parrot_namespace(1)
NAME
parrot_namespace - run a command in a modified namespace.
SYNOPSIS
parrot_cp [options] <command>
DESCRIPTION
parrot_namespace detects whether it is already running under Parrot
and either forks a new mount namespace in the existing Parrot session or
simply executes parrot_run. For applications that only need to make
mount-related changes, parrot_namespace is a drop-in replacement
for parrot_run that automatically handles nested invocations.
OPTIONS
-M, --mount /foo=/bar | Mount (redirect) /foo
to /bar (PARROT_MOUNT_STRING)
|
-m, --ftab-file | Use as a
mountlist (PARROT_MOUNT_FILE)
|
-l,--ld-path <path> |
| Path to ld.so to use.
|
--parrot-path | Path to parrot_run (PARROT_PATH)
|
-v, --version | Show version number
|
-h, --help | Help: Show these options
|
EXIT STATUS
On success, returns zero. On failure, returns non-zero.
EXAMPLES
To run Parrot under Parrot with a modified mount environment,
use parrot_namespace
% parrot_namespace -M /tmp=/tmp/job01 sh
% parrot_mount --unmount /tmp # not allowed
Now in the same shell, we can call parrot_namespace regardless
of whether we're already running under Parrot or not.
% parrot_namespace -m mountfile foo
