NAME

6       rcsclean - clean up working files
7

SYNOPSIS

9       rcsclean [options] [ file ... ]
10

DESCRIPTION

12       rcsclean  removes files that are not being worked on.  rcsclean -u also
13       unlocks and removes files  that  are  being  worked  on  but  have  not
14       changed.
15
16       For  each file given, rcsclean compares the working file and a revision
17       in the corresponding RCS file.  If it finds a difference, it does noth‐
18       ing.   Otherwise,  it  first  unlocks  the revision if the -u option is
19       given, and then removes the working file unless  the  working  file  is
20       writable and the revision is locked.  It logs its actions by outputting
21       the corresponding rcs -u and rm -f commands on the standard output.
22
23       Files are paired as explained in ci(1).  If no file is given, all work‐
24       ing  files in the current directory are cleaned.  Filenames matching an
25       RCS suffix denote RCS files; all others denote working files.
26
27       The number of the revision to which the working file is compared may be
28       attached  to any of the options -n, -q, -r, or -u.  If no revision num‐
29       ber is specified, then if the -u option is given and the caller has one
30       revision  locked,  rcsclean uses that revision; otherwise rcsclean uses
31       the latest revision on the default branch, normally the root.
32
33       rcsclean is useful for clean targets  in  makefiles.   See  also  rcsd‐
34       iff(1),  which  prints  out  the differences, and ci(1), which normally
35       reverts to the previous revision if a file was not changed.
36

OPTIONS

38       -ksubst
39              Use subst style keyword substitution when retrieving  the  revi‐
40              sion for comparison.  See co(1) for details.
41
42       -n[rev]
43              Do not actually remove any files or unlock any revisions.  Using
44              this option will tell you what rcsclean would do  without  actu‐
45              ally doing it.
46
47       -q[rev]
48              Do not log the actions taken on standard output.
49
50       -r[rev]
51              This option has no effect other than specifying the revision for
52              comparison.
53
54       -T     Preserve the modification time on the RCS file even if  the  RCS
55              file  changes  because  a lock is removed.  This option can sup‐
56              press extensive recompilation caused by a make(1) dependency  of
57              some  other  copy of the working file on the RCS file.  Use this
58              option with care; it can suppress recompilation even when it  is
59              needed,  i.e.  when the lock removal would mean a change to key‐
60              word strings in the other working file.
61
62       -u[rev]
63              Unlock the revision if it is locked and no difference is found.
64
65       -V     Print RCS's version number.
66
67       -Vn    Emulate RCS version n.  See co(1) for details.
68
69       -xsuffixes
70              Use suffixes to characterize RCS files.  See ci(1) for details.
71
72       -zzone Use zone as the time zone for keyword  substitution;  see  co(1)
73              for details.
74

EXAMPLES

76              rcsclean  *.c  *.h
77
78       removes  all  working  files  ending  in .c or .h that were not changed
79       since their checkout.
80
81              rcsclean
82
83       removes all working files  in  the  current  directory  that  were  not
84       changed since their checkout.
85

FILES

87       rcsclean accesses files much as ci(1) does.
88

ENVIRONMENT

90       RCSINIT
91              Options  prepended to the argument list, separated by spaces.  A
92              backslash escapes spaces within an option.  The RCSINIT  options
93              are  prepended to the argument lists of most RCS commands.  Use‐
94              ful RCSINIT options include -q, -V, -x, and -z.
95
96       RCS_MEM_LIMIT
97              An integer lim, measured in kilobytes, specifying the  threshold
98              under which commands will try to use memory-based operations for
99              processing the RCS file.  (For RCS files of size  lim  kilobytes
100              or  greater,  RCS will use the slower standard input/output rou‐
101              tines.)  Default value is 256.
102
103       TMPDIR Name of the temporary directory.  If not  set,  the  environment
104              variables TMP and TEMP are inspected instead and the first value
105              found is taken; if  none  of  them  are  set,  a  host-dependent
106              default is used, typically /tmp.
107

DIAGNOSTICS

109       The  exit status is zero if and only if all operations were successful.
110       Missing working files and RCS files are silently ignored.

126       The full documentation for RCS is maintained as a Texinfo  manual.   If
127       the  info(1)  and RCS programs are properly installed at your site, the
128       command
129
130              info rcs
131
132       should give you access to the complete manual.  Additionally,  the  RCS

BUGS

140       At least one file must be given in older Unix versions that do not pro‐
141       vide the needed directory scanning operations.
