rm(1) User Commands rm(1) 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... AVAILABILITY /usr/bin/rm /usr/bin/rmdir SUNWcsu /usr/xpg4/bin/rm SUNWxcu4 DESCRIPTION rm The rm command 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 begins with y (for yes), the file is deleted, otherwise the file remains. If file is a symbolic link, the link will be removed, but the file or directory to which it refers will not be deleted. Users do not need write permission 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 will write a diagnostic message to stan- dard error, do nothing more to the current file, and go on to any remaining files. If the standard input is not a terminal, the command will operate as if the -f option is in effect. rmdir The rmdir command will remove the directory entry specified by each dirname operand, which must refer to an empty direc- tory. Directories will be 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 will be empty when rmdir tries to remove it.

In a write- protected directory, however, files are never removed (whatever their permissions are), but no messages are displayed. If the removal of a write-protected direc- tory is attempted, this option will not suppress an error message. /usr/xpg4/bin/rm -f Do not prompt for confirmation. Do not write diagnostic messages or modify the exit status in the case of non- existent operands. Any previous occurences of the -i option will be ignored. /usr/xpg4/bin/rm -i Interactive. With this option, rm prompts for confir- mation 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 -i Prompt for confirmation. Any occurences of the -f option will be ignored. -r Recursively remove directories and subdirectories in the argument list. The directory will be emptied of files and removed. The user is normally prompted for removal of any write-protected files which the direc- tory contains. The write-protected files are removed without 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 will not be traversed. If the removal of a non-empty, write-protected direc- tory is attempted, the command will always fail (even if the -f option is used), resulting in an error mes- sage. -R Same as -r option. The following options apply to rmdir: -p Allow users to remove the directory dirname and its parent directories which become empty. A message is printed on the standard error about whether the whole SunOS 5.5.1 Last change: 28 Feb 1995 2 rm(1) User Commands rm(1) path is removed or part of the path remains for some reason. -s Suppress the message printed on the standard error when -p is in effect. OPERANDS The following operand is supported: file A path name of a directory entry to be removed. dirname A path name of an empty directory to be removed. EXAMPLES rm The following command: example% rm a.out core removes the directory entries: a.out and core. The following command: example% rm -rf junk removes the directory junk and all its contents, without prompting. rmdir If a directory a in the current directory is empty except it contains a directory b and a/b is empty except it contains a directory c, example% rmdir -p a/b/c will remove all three directories. ENVIRONMENT See environ(5) for descriptions of the following environment variables that affect the execution of rm and rmdir: LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH. 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.

It is forbidden to remove the files "." and ".." in order to avoid the consequences of inadvertently doing something like the following: rm -r .* NOTES A -- permits the user to mark explicitly the end of any com- mand line options, allowing rm to recognize file arguments that begin with a -. As an aid to BSD migration, rm will accept - as a synonym for --. This migration aid may disap- pear in a future release. If a -- and a - both appear on the same command line, the second will be interpreted as a file. SunOS 5.5.1 Last change: 28 Feb 1995 4
