Usage: ci [options] file... Check in revisions of RCS files from working files. Options: -f[REV] Force new entry, even if no content changed. -I[REV] Interactive. -i[REV] Initial checkin; error if RCS file already exists. -j[REV] Just checkin, don't init; error if RCS file does not exist. -k[REV] Compute revision from working file keywords. -q[REV] Quiet mode. -r[REV] Do normal checkin, if REV is specified; otherwise, release lock and delete working file. -l[REV] Like -r, but immediately checkout locked (co -l) afterwards. -u[REV] Like -l, but checkout unlocked (co -u). -M[REV] Reset working file mtime (relevant for -l, -u). -d[DATE] Use DATE (or working file mtime). -mMSG Use MSG as the log message. -nNAME Assign symbolic NAME to the entry; NAME must be new. -NNAME Like -n, but overwrite any previous assignment. -sSTATE Set state to STATE. -t-TEXT Set description to TEXT. -tFILENAME Set description from text read from FILENAME. -T Set the RCS file's modification time to the new revision's time if the former precedes the latter and there is a new revision; preserve the RCS file's modification time otherwise. -V Obsolete; do not use. -VN Emulate RCS version N. -wWHO Use WHO as the author. -xSUFF Specify SUFF as a slash-separated list of suffixes used to identify RCS file names. -zZONE Specify date output format in keyword-substitution and also the default timezone for -dDATE. Multiple flags in {fiIjklMqru} may be used, except for -r, -l, -u, which are mutually exclusive. If specified, REV can be symbolic, numeric, or mixed: symbolic Must have been defined previously (see -n, -N). $ Determine from keyword values in the working file. .N Prepend default branch => DEFBR.N BR.N Use this, but N must be greater than any existing on BR, or BR must be new. BR Latest rev on branch BR + 1 => BR.(L+1), or BR.1 if new branch. If REV is omitted, compute it from the last lock (co -l), perhaps starting a new branch. If there is no lock, use DEFBR.(L+1).
