DRM(1) mpiFileUtils DRM(1) NAME drm - distributed remove SYNOPSIS drm [OPTION] PATH... DESCRIPTION Parallel MPI application to recursively delete a directory and its con- tents. 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 gen- erally 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 -i, --input FILE Read source list from FILE. FILE must be generated by another tool from the mpiFileUtils suite. -o, --output FILE Write the list of items drm attempts to delete to FILE in mpiFileU- tils format. Format can be changed with --text option. -t, --text Must be used with the --output option. Write list of items drm at- tempts to delete to FILE in ascii text format. -l, --lite Walk file system without stat. --stat Walk file system with stat. --exclude REGEX Do not remove items whose full path matches REGEX, processed by regexec(3). --match REGEX Only remove items whose full path matches REGEX, processed by regexec(3). --name Change --exclude and match to apply to item name rather than its full path. --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. --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 op- tion with --dryrun. -T, --traceless Delete child items without updating the mtime on their parent direc- tory. --progress N Print progress message to stdout approximately every N seconds. The number of seconds must be a non-negative integer. A value of 0 dis- ables progress messages. -v, --verbose Run in verbose mode. -q, --quiet Run tool silently. No output is printed. -h, --help Print a brief message listing the 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 direc- tory 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 <https://github.com/hpc/mpifileutils> AUTHOR HPC COPYRIGHT 2022, LLNL/LANL/UT-Battelle/DDN 0.12 Jan 29, 2025 DRM(1)
