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
