NAME
       srm - securely remove files or directories

SYNOPSIS
       ssrrmm [OPTION]... FILE...

DESCRIPTION
       ssrrmm  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.

       ssrrmm,  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".

OOPPTTIIOONNSS
       -dd, --ddiirreeccttoorryy
              ignored (for compatibility with rrmm((11)))

       -ff, --ffoorrccee
              ignore nonexistent files, never prompt

       -ii, --iinntteerraaccttiivvee
              prompt before any removal

       -rr, -RR, --rreeccuurrssiivvee
              remove the contents of directories recursively

       -ss, --ssiimmppllee
              only overwrite with a single pass of random data

       -mm, --mmeeddiiuumm
              overwrite the file with 7 US DoD compliant passes  (0xF6,  0x00,
              0xFF, random, 0x00, 0xFF, random)

       -zz, --zzeerroo
              after overwriting, zero blocks used by file

       -nn, --nnoouunnlliinnkk
              overwrite file, but do not rename or unlink it

       -vv, --vveerrbboossee
              explain what is being done

       --hheellpp display this help and exit

       --vveerrssiioonn
              output version information and exit

NNOOTTEESS
       ssrrmm can not remove write protected files owned by another user, regard-
       less of the permissions on the directory containing the file.

       The -ss option overrides the -mm option, if both are present.  If neither
       is specified, the 35-pass Gutmann algorithm is used.

       Development  and  discussion  of  ssrrmm is carried out at        forge.net/project/?groupid=3297>,  which  is   also   accessible   via
       .
