در اینجا به بررسی دستور mkdir و rm می پردازیم .

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  –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
       Remove (unlink) the FILE(s).

       -f, –force
              ignore nonexistent files, 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

       -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.
