- rrccssddiiffff runs ddiiffff(1) to compare two revisions of each RCS
- file given.
-
- Pathnames matching an RCS suffix denote RCS files; all
- others denote working files. Names are paired as
- explained in ccii(1).
-
- The option --qq suppresses diagnostic output. Zero, one, or
- two revisions may be specified with --rr. The option
- --kk_s_u_b_s_t affects keyword substitution when extracting
- revisions, as described in ccoo(1); for example,
- --kkkk --rr11..11 --rr11..22 ignores differences in keyword values when
- comparing revisions 11..11 and 11..22. To avoid excess output
- from locker name substitution, --kkkkvvll is assumed if (1) at
- most one revision option is given, (2) no --kk option is
- given, (3) --kkkkvv is the default keyword substitution, and
- (4) the working file's mode would be produced by ccoo --ll.
- See ccoo(1) for details about --VV and --xx. Otherwise, all
- options of ddiiffff(1) that apply to regular files are
- accepted, with the same meaning as for ddiiffff.
-
- If both _r_e_v_1 and _r_e_v_2 are omitted, rrccssddiiffff compares the
- latest revision on the default branch (by default the
- trunk) with the contents of the corresponding working
- file. This is useful for determining what you changed
- since the last checkin.
-
- If _r_e_v_1 is given, but _r_e_v_2 is omitted, rrccssddiiffff compares
- revision _r_e_v_1 of the RCS file with the contents of the
- corresponding working file.
-
- If both _r_e_v_1 and _r_e_v_2 are given, rrccssddiiffff compares
- revisions _r_e_v_1 and _r_e_v_2 of the RCS file.
-
- Both _r_e_v_1 and _r_e_v_2 may be given numerically or
- symbolically.

- The command
-
- rrccssddiiffff ff..cc
-
- compares the latest revision on the default branch of the
- RCS file to the contents of the working file ff..cc.
