rm



RM(1)                       General Commands Manual                      RM(1)


NAME

     rm - remove directory entries


SYNOPSIS

     rm [-dfiPRr] file ...


DESCRIPTION

     The rm utility attempts to remove the non-directory type files specified
     on the command line.  If the permissions of the file do not permit
     writing, and the standard input device is a terminal, the user is
     prompted (on the standard error output) for confirmation.

     The options are as follows:

     -d      Attempt to remove directories as well as other types of files.

     -f      Attempt to remove the files without prompting for confirmation,
             regardless of the file's permissions.  If the file does not
             exist, do not display a diagnostic message or modify the exit
             status to reflect an error.  The -f option overrides any previous
             -i options.

     -i      Request confirmation before attempting to remove each file,
             regardless of the file's permissions, or whether or not the
             standard input device is a terminal.  The -i option overrides any
             previous -f options.

     -P      Overwrite regular files before deleting them.  Files are
             overwritten once with a random pattern.  Files with multiple
             links will be unlinked but not overwritten.

     -R      Attempt to remove the file hierarchy rooted in each file
             argument.  The -R option implies the -d option.  If the -i option
             is specified, the user is prompted for confirmation before each
             directory (and its contents) are processed.  If the user does not
             respond affirmatively, the file hierarchy rooted in that
             directory is skipped.

     -r      Equivalent to -R.

     The rm utility removes symbolic links, not the files referenced by the
     links.

     It is an error to attempt to remove the files ``.'' or ``..''.  It is
     forbidden to remove the file ``..'' merely to avoid the antisocial
     consequences of inadvertently doing something like ``rm -r .*''.


EXIT STATUS

     The rm utility exits 0 if all of the named files or file hierarchies were
     removed, or if the -f option was specified and all of the existing files
     or file hierarchies were removed.  If an error occurs, rm exits with a
     value >0.


EXAMPLES

     Recursively remove all files contained within the foobar directory
     hierarchy:

           $ rm -rf foobar

     Either of these commands will remove the file -f:

           $ rm -- -f
           $ rm ./-f


SEE ALSO

     rmdir(1), unlink(2), fts(3), symlink(7)


STANDARDS

     The rm utility is compliant with the IEEE Std 1003.1-2008 (``POSIX.1'')
     specification.

     The flags [-dP] are extensions to that specification.


HISTORY

     An rm command appeared in Version 1 AT&T UNIX.

     The rm utility differs from historical implementations in that the -f
     option only masks attempts to remove non-existent files instead of
     masking a large variety of errors.

     Also, historical BSD implementations prompted on the standard output, not
     the standard error output.

     The interactive mode used to be a dsw command, a carryover from the
     ancient past with an amusing etymology.


BUGS

     The -P option assumes that both the underlying file system and storage
     medium write in place.  This is true for the FFS and MS-DOS file systems
     and magnetic hard disks, but not true for most flash storage.  In
     addition, only regular files are overwritten; other types of files are
     not.
