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=<path>
Use <path> 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
