NAME

       rm, rmdir - remove directory entries

SYNOPSIS

       /usr/bin/rm [-f] [-i] file...

       /usr/bin/rm -rR [-f] [-i] dirname... [file]...

       /usr/xpg4/bin/rm [-fiRr] file...

       /usr/bin/rmdir [-ps] dirname...

   ksh93
       /usr/bin/rmdir [-eps] dirname...

DESCRIPTION

   /usr/bin/rm /usr/xpg4/bin/rm
       The  rm	utility removes the directory entry specified by each file argument. 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 directory to which it refers is not deleted. Users do not need write per-
       mission 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.

   ksh93
       The  rmdir built-in in ksh93 is associated with the /bin and /usr/bin paths. It is invoked when rmdir is executed without a pathname prefix
       and the pathname search finds a /bin/rmdir or /usr/bin/rmdir executable.

       rmdir deletes each given directory. The directory must be empty and contain no entries other than . or ... If a directory and  a  subdirec-
       tory  of  that  directory  are specified as operands, the subdirectory must be specified before the parent, so that the parent directory is
       empty when rmdir attempts to remove it.

OPTIONS

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

       -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 standard input is not a terminal and the -i option is not used.

	     Symbolic links that are encountered with this option is not traversed.

	     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.

       -R    Same as -r option.

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

       -f    Removes  all  files  (whether write-protected or not) in a directory without prompting the user. In a write-protected directory, how-
	     ever, files are never removed (whatever their permissions are), but no messages are displayed. If the removal  of	a  write-protected
	     directory is attempted, this option does not suppress an error message.

       -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.

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

       -f    Does not prompt for confirmation. Does not write diagnostic messages or modify the exit status in the case of non-existent  operands.
	     Any previous occurrences of the -i option is ignored.

       -i    Prompts for confirmation. Any occurrences of the -f option is ignored.

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

       -p    Allows users to remove the directory dirname and its parent directories 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.

   ksh93
       The following options are supported for the rmdir built-in for ksh93:

       -e			     Ignore each non-empty directory failure.
       --ignore-fail-on-non-empty

       -p			     Remove each explicit directory argument directory that becomes empty after its child directories are removed.
       --parents

       -s			     Suppress the message printed on the standard error when -p is in effect.
       --suppress

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.

USAGE

       See largefile(5) for the description of the behavior of rm and rmdir when encountering files greater than  or  equal  to  2  Gbyte  (  2^31
       bytes).

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 contains a directory b, and a/b is empty except that it contains a
       directory c, the following command removes all three directories:

	 example% rmdir -p a/b/c

ENVIRONMENT VARIABLES

       See environ(5) 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 expression 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
       collating 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(5).

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.

   ksh93
       The following exit values are returned:

       0     Successful completion. All directories deleted successfully.

       >0    An error occurred. One or more directories could not be deleted.

DIAGNOSTICS

       All messages are generally self-explanatory.

       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 consequences 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.
