help

  • Usage: rm [OPTION]... [FILE]...
    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 protection 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.
