NAME
rcsclean - clean up working files
SYNOPSIS
rcsclean [_o_p_t_i_o_n_s] [ _f_i_l_e ... ]
DESCRIPTION
rcsclean removes working files that were checked out and
never modified. For each _f_i_l_e 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 revision 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 and rm -f commands on
the standard output.
If no _f_i_l_e is given, all working files in the current direc-
tory are cleaned. Pathnames matching an RCS suffix denote
RCS files; all others denote working files. Names are
paired as explained in ci(1).
The number of the revision to which the working file is com-
pared 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), which prints out the differences, and ci(1),
which normally asks whether to check in a file if it was not
changed.
OPTIONS
-k_s_u_b_s_t
Use _s_u_b_s_t style keyword substitution when retrieving
the revision for comparison. See co(1) for details.
-n[_r_e_v]
Do not actually remove any files or unlock any revi-
sions. Using this option will tell you what rcsclean
would do without actually doing it.
-q[_r_e_v]
Do not log the actions taken on standard output.
-r[_r_e_v]
This option has no effect other than specifying the
revision for comparison.
-u[_r_e_v]

RCSCLEAN(1) USER COMMANDS RCSCLEAN(1)
Unlock the revision if it is locked and no difference
is found.
-V_n Emulate RCS version _n. See co(1) for details.
-x_s_u_f_f_i_x_e_s
Use _s_u_f_f_i_x_e_s to characterize RCS files. See ci(1) for
details.
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 checkout.
FILES
rcsclean accesses files much as ci(1) does.
ENVIRONMENT
RCSINIT
options prepended to the argument list, separated by
spaces. A backslash escapes spaces within an option.
The RCSINIT options are prepended to the argument lists
of most RCS commands. Useful RCSINIT options include
-q, -V, and -x.
DIAGNOSTICS
The exit status is zero if and only if all operations were
successful. Missing working files and RCS files are
silently ignored.

BUGS
At least one _f_i_l_e must be given in older Unix versions that
do not provide the needed directory scanning operations.
