For each _file_ given, **rcsclean** compares the working file and a revision in the corresponding RCS file. If it finds a difference, it does nothing. Otherwise, it first unlocks the revi‐ sion if the **-u** option is given, and then removes the working file unless the working file is writable and the revision is locked. It logs its actions by outputting the corresponding **rcs** ### -u -f Files are paired as explained in [**ci**(1)](https://www.chedong.com/phpMan.php/man/ci/1/markdown). If no _file_ is given, all working files in the cur‐ rent directory are cleaned. Filenames matching an RCS suffix denote RCS files; all others denote working files. The number of the revision to which the working file is compared may be attached to any of the options **-n**, **-q**, **-r**, or **-u**. If no revision number is specified, then if the **-u** option is given and the caller has one revision locked, **rcsclean** uses that revision; otherwise **rcsclean** uses the latest revision on the default branch, normally the root. **rcsclean** is useful for **clean** targets in makefiles. See also [**rcsdiff**(1)](https://www.chedong.com/phpMan.php/man/rcsdiff/1/markdown), which prints out the differences, and [**ci**(1)](https://www.chedong.com/phpMan.php/man/ci/1/markdown), which normally reverts to the previous revision if a file was not changed. ## OPTIONS ### -k Use _subst_ style keyword substitution when retrieving the revision for comparison. See [**co**(1)](https://www.chedong.com/phpMan.php/man/co/1/markdown) for details. ### -n Do not actually remove any files or unlock any revisions. Using this option will tell you what **rcsclean** would do without actually doing it. ### -q Do not log the actions taken on standard output. ### -r This option has no effect other than specifying the revision for comparison. ### -T lock is removed. This option can suppress extensive recompilation caused by a [**make**(1)](https://www.chedong.com/phpMan.php/man/make/1/markdown) dependency of some other copy of the working file on the RCS file. Use this option with care; it can suppress recompilation even when it is needed, i.e. when the lock removal would mean a change to keyword strings in the other working file. ### -u Unlock the revision if it is locked and no difference is found. ### -V ### -V ### -x Use _suffixes_ to characterize RCS files. See [**ci**(1)](https://www.chedong.com/phpMan.php/man/ci/1/markdown) for details. ### -z ## EXAMPLES **rcsclean** ***.c** ***.h** removes all working files ending in **.c** or **.h** that were not changed since their checkout. **rcsclean** removes all working files in the current directory that were not changed since their check‐ out. ## FILES **rcsclean** accesses files much as [**ci**(1)](https://www.chedong.com/phpMan.php/man/ci/1/markdown) does. ## ENVIRONMENT **RCSINIT** Options prepended to the argument list, separated by spaces. A backslash escapes spa‐ ces within an option. The **RCSINIT** options are prepended to the argument lists of most RCS commands. Useful **RCSINIT** options include **-q**, **-V**, **-x**, and **-z**. **RCS**___**MEM**___**LIMIT** Normally, for speed, commands either memory map or copy into memory the RCS file if its size is less than the _memory-limit_, currently defaulting to ``unlimited''. Other‐ wise (or if the initially-tried speedy ways fail), the commands fall back to using standard i/o routines. You can adjust the memory limit by setting **RCS**___**MEM**___**LIMIT** to a numeric value _lim_ (measured in kilobytes). An empty value is silently ignored. As a side effect, specifying **RCS**___**MEM**___**LIMIT** inhibits fall-back to slower routines. **TMPDIR** Name of the temporary directory. If not set, the environment variables **TMP** and **TEMP** are inspected instead and the first value found is taken; if none of them are set, a host-dependent default is used, typically **/tmp**. ## DIAGNOSTICS The exit status is zero if and only if all operations were successful. Missing working files and RCS files are silently ignored. ## IDENTIFICATION Author: Walter F. Tichy. Manual Page Revision: 5.10.1; Release Date: 2022-02-19. Copyright © 2010-2022 Thien-Thi Nguyen.
