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.
