drm === SYNOPSIS -------- **drm [OPTION] PATH...** DESCRIPTION ----------- Parallel MPI application to recursively delete a directory and its contents. drm is a tool for removing files recursively in parallel. drm behaves like `rm -rf`, but it is faster. .. note:: DO NOT USE SHELL REGEX!!! The --match and --exclude options use POSIX regex syntax. Because of this make sure that the shell does not try to interpret your regex before it gets passed to the program. You can generally use quotes around your regex to prevent the shell from expanding. An example of this using the --match option with --dryrun would be: ``mpirun -np 128 drm --dryrun -v --name --match 'file_.*' /path/to/dir/*`` OPTIONS ------- .. option:: -i, --input FILE Read source list from FILE. FILE must be generated by another tool from the mpiFileUtils suite. .. option:: -l, --lite Walk file system without stat. .. option:: --exclude REGEX Do not remove items whose full path matches REGEX, processed by :manpage:`regexec(3)`. .. option:: --match REGEX Only remove items whose full path matches REGEX, processed by :manpage:`regexec(3)`. .. option:: --name Change --exclude and match to apply to item name rather than its full path. .. option:: --dryrun Print a list of files that **would** be deleted without deleting them. This is useful to check list of items satisfying --exclude or --match options before actually deleting anything. .. option:: --aggressive This option will delete files during the walk phase, and then delete directories by level after the walk in drm. You cannot use this option with --dryrun. .. option:: -T, --traceless Delete child items without updating the mtime on their parent directory. .. option:: -v, --verbose Run in verbose mode. .. option:: -q, --quiet Run tool silently. No output is printed. .. option:: -h, --help Print a brief message listing the :manpage:`drm(1)` options and usage. EXAMPLES -------- 1. To delete a directory and its contents: ``mpirun -np 128 drm -v /dir/to/delete`` 2. Delete all items (files and directories) ending with .core from directory tree: ``mpirun -np 128 drm --match '.core$' /dir/to/delete/from`` 3. List items that would be deleted without removing them: ``mpirun -np 128 drm --dryrun --match '.core$' /dir/to/delete/from`` 4. Delete all items named foo: ``mpirun -np 128 drm --name --match '^foo$' /dir/to/delete/from`` SEE ALSO -------- The mpiFileUtils source code and all documentation may be downloaded from
