srm - securely remove files or directories SYNOPSIS
srm [OPTION]... FILE... DESCRIPTION
srm removes each specified file by overwriting, renaming, and truncating it before unlinking. This prevents other people from undeleting or recovering any information about the file from the command line. srm, like every program that uses the getopt function to parse its arguments, lets you use the -- option to indicate that all following arguments are non-options. To remove a file called '-f' in the current directory, you could type either "srm -- -f" or "srm ./-f". OPTIONS
-d, --directory ignored (for compatibility with rm(1)) -f, --force ignore nonexistent files, never prompt -i, --interactive prompt before any removal -r, -R, --recursive remove the contents of directories recursively -s, --simple only overwrite with a single pass of random data -m, --medium overwrite the file with 7 US DoD compliant passes (0xF6, 0x00, 0xFF, random, 0x00, 0xFF, random) -z, --zero after overwriting, zero blocks used by file -n, --nounlink overwrite file, but do not rename or unlink it -v, --verbose explain what is being done --help display this help and exit --version output version information and exit NOTES
srm can not remove write protected files owned by another user, regardless of the permissions on the directory containing the file. The -s option overrides the -m option, if both are present. If neither is specified, the 35-pass Gutmann algorithm is used. Development and discussion of srm is carried out at <http://sourceforge.net/project/?group_id=3297>, which is also accessible via <http://srm.sourceforge.net>. SEE ALSO

RM(1) User Commands RM(1) NAME
rm - remove files or directories SYNOPSIS
rm [OPTION]... [FILE]... DESCRIPTION
This manual page documents the GNU version of rm. rm removes each specified file. By default, it does not remove directories. If the -I or --interactive=once option is given, and there are more than three files or the -r, -R, or --recursive are given, then rm prompts the user for whether to proceed with the entire operation. If the response is not affirmative, the entire command is aborted. Otherwise, if a file is unwritable, standard input is a terminal, and the -f or --force option is not given, or the -i or --interac- tive=always option is given, rm prompts the user for whether to remove the file. If the response is not affirmative, the file is skipped. OPTIONS
Remove (unlink) the FILE(s). -f, --force ignore nonexistent files and arguments, never prompt -i prompt before every removal -I prompt once before removing more than three files, or when removing recursively; less intrusive than -i, while still giving protec- tion against most mistakes --interactive[=WHEN] prompt according to WHEN: never, once (-I), or always (-i); without WHEN, prompt always --one-file-system when removing a hierarchy recursively, skip any directory that is on a file system different from that of the corresponding command line argument --no-preserve-root do not treat '/' specially --preserve-root do not remove '/' (default) -r, -R, --recursive remove directories and their contents recursively -d, --dir remove empty directories -v, --verbose explain what is being done --help display this help and exit --version output version information and exit By default, rm does not remove directories. Use the --recursive (-r or -R) option to remove each listed directory, too, along with all of its contents. To remove a file whose name starts with a '-', for example '-foo', use one of these commands: rm -- -foo rm ./-foo Note that if you use rm to remove a file, it might be possible to recover some of its contents, given sufficient expertise and/or time. For greater assurance that the contents are truly unrecoverable, consider using shred. AUTHOR
