rcsclean - clean up working files
SSYYNNOOPPSSIISS
rrccsscclleeaann [_o_p_t_i_o_n_s] [ _f_i_l_e ... ]
DDEESSCCRRIIPPTTIIOONN
rrccsscclleeaann removes files that are not being worked on.
rrccsscclleeaann --uu also unlocks and removes files that are being
worked on but have not changed.
For each _f_i_l_e given, rrccsscclleeaann 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 revision if the --uu 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 rrccss --uu and rrmm --ff commands
on the standard output.
Files are paired as explained in ccii(1). If no _f_i_l_e is
given, all working files in the current directory are
cleaned. Pathnames 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 --nn, --qq, --rr,
or --uu. If no revision number is specified, then if the --uu
option is given and the caller has one revision locked,
rrccsscclleeaann uses that revision; otherwise rrccsscclleeaann uses the
latest revision on the default branch, normally the root.
rrccsscclleeaann is useful for cclleeaann targets in makefiles. See
also rrccssddiiffff(1), which prints out the differences, and
ccii(1), which normally reverts to the previous revision if
a file was not changed.
OOPPTTIIOONNSS
--kk_s_u_b_s_t
Use _s_u_b_s_t style keyword substitution when retriev-
ing the revision for comparison. See ccoo(1) for
details.
--nn[_r_e_v]
Do not actually remove any files or unlock any
revisions. Using this option will tell you what
rrccsscclleeaann would do without actually doing it.
--qq[_r_e_v]
Do not log the actions taken on standard output.
--rr[_r_e_v]
This option has no effect other than specifying the
revision for comparison.

RCSCLEAN(1) RCSCLEAN(1)
--TT Preserve the modification time on the RCS file even
if the RCS file changes because a lock is removed.
This option can suppress extensive recompilation
caused by a mmaakkee(1) 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.
--uu[_r_e_v]
Unlock the revision if it is locked and no differ-
ence is found.
--VV Print RCS's version number.
--VV_n Emulate RCS version _n. See ccoo(1) for details.
--xx_s_u_f_f_i_x_e_s
Use _s_u_f_f_i_x_e_s to characterize RCS files. See ccii(1)
for details.
--zz_z_o_n_e Use _z_o_n_e as the time zone for keyword substitution;
see ccoo(1) for details.
EEXXAAMMPPLLEESS
rrccsscclleeaann **..cc **..hh
removes all working files ending in ..cc or ..hh that were not
changed since their checkout.
rrccsscclleeaann
removes all working files in the current directory that
were not changed since their checkout.
FFIILLEESS
rrccsscclleeaann accesses files much as ccii(1) does.
EENNVVIIRROONNMMEENNTT
RRCCSSIINNIITT
options prepended to the argument list, separated
by spaces. A backslash escapes spaces within an
option. The RRCCSSIINNIITT options are prepended to the
argument lists of most RCS commands. Useful
RRCCSSIINNIITT options include --qq, --VV, --xx, and --zz.
DDIIAAGGNNOOSSTTIICCSS
The exit status is zero if and only if all operations were
successful. Missing working files and RCS files are
silently ignored.

BBUUGGSS
At least one _f_i_l_e must be given in older Unix versions
that do not provide the needed directory scanning opera-
tions.
