rrrcccsssdddiiiffffff runs dddiiiffffff(1) to compare two revisions of each RCS file given. A
file name ending in ,,,vvv is an RCS file name, otherwise a working file
name. rrrcccsssdddiiiffffff derives the working file name from the RCS file name and
vice versa, as explained in cccooo(1). Pairs consisting of both an RCS and a
working file name may also be specified.
The option ---qqq suppresses diagnostic output. Zero, one, or two revisions
may be specified with ---rrr. The option ---kkk_s_u_b_s_t affects keyword
substitution when extracting revisions, as described in cccooo(1); for
example, ---kkkkkk\\\ ---rrr111...111\\\ ---rrr111...222 ignores differences in keyword values when
comparing revisions 111...111 and 111...222. To avoid excess output from locker name
substitution, ---kkkkkkvvvlll is assumed if (1) at most one revision option is
given, (2) no ---kkk option is given, (3) ---kkkkkkvvv is the default keyword
substitution, and (4) the working file's mode would be produced by cccooo\\\
---lll. See cccooo(1) for details about ---VVV. Otherwise, all options of dddiiiffffff(1)
that apply to regular files are accepted, with the same meaning as for
dddiiiffffff.
If both _r_e_v_1 and _r_e_v_2 are omitted, rrrcccsssdddiiiffffff 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, rrrcccsssdddiiiffffff 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, rrrcccsssdddiiiffffff 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
rrrcccsssdddiiiffffff fff...ccc
compares the latest revision on the default branch of the RCS file
RRRCCCSSS///fff...ccc,,,vvv to the contents of the working file fff...ccc.

Exit status is 0 for no differences during any comparison, 1 for some
differences, 2 for trouble.
