Sissejuhatus

Käsu rm ehk remove abil on UNIXi laadsetes operatsioonisüsteemides võimalik kustutada faile, kaustu ja sümboolseid linke. Rm ei hävita faili vaid eemaldab kõik viited mis selle faili suunas olemas olid, mis muudab faili operatsioonisüsteemi jaoks nähtamatuks ning antud faili poolt hõivatud kettaruum muutub "vabaks". Seega ei kustu fail reaalselt enne kui andmekandjal samade sektorite peale mingi muu info kirjutatakse. Hävitamaks faili täielikult tuleb kasutada [1] käsku .

Valikud

      rm [valik] [fail]

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
      --interactive=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

      -f, --force - kustutab olenemata võimalikust veateatest ja ei küsi kinnitust. Kui faili pole olemas ignoreerib ning täidab käsu siiski.

      -i - küsib enne igat kustutamist kas olete kindel, et soovite kustutada

      -I - kustutades rekursiivselt või rohkem kui kolme faili, küsib ühe korra kinnitust;

      --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.
