out again because all RCS commands automatically check to see if a file is compressed before
performing an operation on them. The checked-out working file is not compressed.
Note: If an RCS file is in the midst of a check-in operation, it cannot be accessed by any RCS
command.
Options
ci accepts the following options:
–B forces ci to check in the revision using binary format. If the revision is actually a
text file,
RCS still produces correct results, but may work less efficiently than it would
if text format was used. –B cannot be specified if the RCS file already contains revi-
sions checked in using text format or the RCS file was created with the rcs –T com-
mand.
–ddate uses date for the check-in date and time. The date option may be specified in free
format as explained in co(1). This option is useful for altering the check-in date, and
for –k if no date is available.
–Ffile...
provides an alternate way to specify file names. The given file is a text file contain-
ing a list of file names, one file name per line. ci checks in all the files named in file,
using the options specified on the command line. Multiple –F options may be speci-
fied on the command line, and can either be grouped together or interspersed between
options.
–f[rev]
forces a check in. The new revision is checked in even if it is not different from the
preceding one.
–G sets the
RCS
file date to the current date. Normally, when updating, the date stamp of
the RCS file is set to the check-in date of the head revision.
–g sets the check-in date of the revision to the modification date of the working file.
Normally, ci uses the current time as the check-in date.
–h[rev]
uses the –h (half-hearted) option to diff(1) to produce the set of changes for this
revision. Normally, this half-hearted algorithm is used only if diff runs out of sys-
tem resources using the normal algorithm.
–I allows ci to accept redirected input from a file or from a pipe instead of standard
input. Input is a sequence of strings separated by lines containing only a single dot.
–k[rev]
searches the working file for keyword values to determine its revision number, cre-
ation date, state, and author (see co(1)). ci then assigns these values to the
