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 <file> 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
