DESCRIPTION
   /usr/bin/rm /usr/xpg4/bin/rm
       The rm utility removes the directory entry specified by each file argu‐
       ment. If a file has no write permission and the  standard  input  is  a
       terminal,  the  full  set  of  permissions  (in octal) for the file are
       printed followed by a question mark. This is a prompt for confirmation.
       If  the  answer is affirmative, the file is deleted, otherwise the file
       remains.


       If file is a symbolic link, the link is removed, but the file or direc‐
       tory to which it refers is not deleted. Users do not need write permis‐
       sion to remove a symbolic link, provided they have write permissions in
       the directory.


       If  multiple  files  are  specified and removal of a file fails for any
       reason, rm writes a diagnostic message to standard  error,  do  nothing
       more to the current file, and go on to any remaining files.


       If the standard input is not a terminal, the utility operates as if the
       -f option is in effect.

   /usr/bin/rmdir
       The rmdir utility removes the directory entry specified by each dirname
       operand, which must refer to an empty directory.


       Directories  are processed in the order specified. If a directory and a
       subdirectory of that directory are specified in a single invocation  of
       rmdir,  the  subdirectory must be specified before the parent directory
       so that the parent directory is empty when rmdir tries to remove it.

OPTIONS
       The following options are supported for /usr/bin/rm:

       -r, -R, --recursive

           Recursively removes directories and subdirectories in the  argument
           list.  The  directory  is emptied of files and removed. The user is
           normally prompted for removal of any  write-protected  files  which
           the directory contains. The write-protected files are removed with‐
           out prompting, however, if the -f option is used, or if  the  stan‐
           dard input is not a terminal and the -i option is not used.

           Symbolic  links  that  are encountered with this option is not tra‐
           versed.

           If  the  removal  of  a  non-empty,  write-protected  directory  is
           attempted,  the  utility  always  fails  (even  if the -f option is
           used), resulting in an error message.


       --help

           Displays usage message and exits with return code 0.

       -f, --force

           Removes files (even if  write-protected)  in  a  directory  without
           prompting  the user. In a write-protected directory, however, files
           are never removed (whatever their permissions are) and no  messages
           are displayed.

       -i

           Interactive.  With  this option, rm prompts for confirmation before
           removing any files. It overrides  the  -f  option  and  remains  in
           effect even if the standard input is not a terminal.

       -I

           Prompts  for  confirmation if there more than three files; its less
           intrusive than -i option. It overrides the -f option and remains in
           effect even if the standard input is not a terminal

       --interactive[=WHEN]

           Prompts  according to WHEN: never, once (-I), or always (-i). With‐
           out WHEN, prompts always. It overrides the -f option and remains in
           effect even if the standard input is not terminal.

       --one-file-system

           When  removing recursively, skip directory from different file sys‐
           tem from that of the corresponding command line argument.

       --preserve-root

           Do not operate recursively on `/'.

       --no-preserve-root

           Do not treat `/' specially. This is the default.

       -v, --verbose

           Give a diagnostic for every file processed.


   /usr/xpg4/bin/rm
       The following options are supported for /usr/xpg4/bin/rm:

       -r, -R

           Recursively removes directories and subdirectories in the  argument
           list.  The  directory  is emptied of files and removed. The user is
           normally prompted for removal of any  write-protected  files  which
           the directory contains. The write-protected files are removed with‐
           out prompting, however, if the -f option is used, or if  the  stan‐
           dard input is not a terminal and the -i option is not used.

           Symbolic  links  that  are encountered with this option is not tra‐
           versed.

           If  the  removal  of  a  non-empty,  write-protected  directory  is
           attempted,  the  utility  always  fails  (even  if the -f option is
           used), resulting in an error message.


       -f

           Does not prompt for confirmation. Does not  write  diagnostic  mes‐
           sages  or  modify the exit status in the case of non-existent oper‐
           ands. Any previous occurrences of the -i option is ignored.


       -i

           Prompts for confirmation. If the options -i and -f are both  speci‐
           fied, the last option takes the precedence.


   /usr/bin/rmdir
       The following options are supported for /usr/bin/rmdir only:

       --help

           Displays usage message and exits with status 0.


       --ignore-fail-on-non-empty

           Ignores failure that is solely because a directory is non-empty.


       -p, --parents

           Allows  users to remove the directory dirname and its parent direc‐
           tories which become empty. A message is printed to  standard  error
           if all or part of the path could not be removed.


       -s

           Suppresses  the message printed on the standard error when -p is in
           effect.


       -v, --verbose

           Outputs a diagnostic for the directory or directories processed.


OPERANDS
       The following operands are supported:

       file

           Specifies the pathname of a directory entry to be removed.


       dirname

           Specifies the pathname of an empty directory to be removed.


EXAMPLES
       The following examples are valid for the commands shown.

   /usr/bin/rm, /usr/xpg4/bin/rm
       Example 1 Removing Directories



       The following command removes the directory entries a.out and core:


         example% rm a.out core


       Example 2 Removing a Directory without Prompting



       The following command removes the directory junk and all its  contents,
       without prompting:


         example% rm -rf junk


   /usr/bin/rmdir
       Example 3 Removing Empty Directories



       If a directory a in the current directory is empty, except that it con‐
       tains a directory b, and a/b is empty except that it contains a  direc‐
       tory c, the following command removes all three directories:


         example% rmdir -p a/b/c


ENVIRONMENT VARIABLES
       See  environ(7) for descriptions of the following environment variables
       that affect the execution of rm and rmdir:  LANG,  LC_ALL,  LC_COLLATE,
       LC_CTYPE, LC_MESSAGES, and NLSPATH.


       Affirmative  responses are processed using the extended regular expres‐
       sion defined for the yesexpr keyword in the LC_MESSAGES category of the
       user's  locale. The locale specified in the LC_COLLATE category defines
       the behavior of ranges, equivalence classes, and  multi-character  col‐
       lating  elements used in the expression defined for yesexpr. The locale
       specified in LC_CTYPE  determines  the  locale  for  interpretation  of
       sequences of bytes of text data a characters, the behavior of character
       classes used in the expression defined for the yesexpr. See locale(7).

EXIT STATUS
       The following exit values are returned:

       0

           If the -f option was not specified, all the named directory entries
           were  removed;  otherwise, all the existing named directory entries
           were removed.


       >0

           An error occurred.


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:

   /usr/bin/rm, /usr/bin/rmdir
       tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) ATTRIBUTE  TYPEAT‐

DIAGNOSTICS
       It is forbidden to remove the files "." and ".." in order to avoid  the
       consequences of inadvertently doing something like the following:

         example% rm -r .*



       It  is  forbidden  to  remove the file "/" in order to avoid the conse‐
       quences of inadvertently doing something like:

         example% rm -rf $x/$y



       or

         example% rm -rf /$y



       when $x and $y expand to empty strings.

NOTES
       A − permits the user to mark explicitly the end  of  any  command  line
       options,  allowing  rm to recognize file arguments that begin with a −.
       As an aid to BSD migration, rm accepts −− as  a  synonym  for  −.  This
       migration  aid  may disappear in a future release. If a −− and a − both
       appear on the same command line, the second is interpreted as a file.
