NAME
srm - securely remove files or directories
SYNOPSIS
srm [OPTION]... FILE...
DESCRIPTION
srm removes each specified file by overwriting, renaming, and truncat-
ing it before unlinking. This prevents other people from undeleting or
recovering any information about the file from the command line. By
default srm uses 35 passes to overwrite the file?셲 contents. If this
seems overkill you can use use the --dod or --openbsd or --simple
option which use less passes.
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
rm -- -f
or
rm ./-f
OPTIONS
Remove (unlink) the FILE(s).
-d, --directory
ignored (for compatability 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 the file with a single pass of random data
-P, --openbsd
OpenBSD compatible rm. Overwrite regular files before deleting
them. Files are overwritten three times, first with the byte
pattern 0xff, then 0x00, and then 0xff again, before they are
deleted. Files with multiple links will be unlinked but not
overwritten.
-D, --dod
Dod compliant 7-pass overwrite.
-v, --verbose
explain what is being done
-h, --help
display this help and exit
-V, --version
output version information and exit
NOTES
srm can not remove write protected files owned by another user, regard-
less of the permissions on the directory containing the file.
Development and discussion of srm is carried out at
http://source-forge.net/project/?group_id=3297 which is also accessible via
http://srm.sourceforge.net.
