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
