NAME
rcsdiff - compare RCS revisions
SYNOPSIS
rcsdiff [ -k_s_u_b_s_t ] [ -q ] [ -r_r_e_v_1 [ -r_r_e_v_2 ] ] [ -V_n ] [
-x_s_u_f_f_i_x_e_s ] [ _d_i_f_f _o_p_t_i_o_n_s ] _f_i_l_e ...
DESCRIPTION
rcsdiff runs diff(1) to compare two revisions of each RCS
file given.
Pathnames matching an RCS suffix denote RCS files; all oth-
ers denote working files. Names are paired as explained in
ci(1).
The option -q suppresses diagnostic output. Zero, one, or
two revisions may be specified with -r. The option -k_s_u_b_s_t
affects keyword substitution when extracting revisions, as
described in co(1); for example, -kk -r1.1 -r1.2 ignores
differences in keyword values when comparing revisions 1.1
and 1.2. To avoid excess output from locker name substitu-
tion, -kkvl is assumed if (1) at most one revision option is
given, (2) no -k option is given, (3) -kkv is the default
keyword substitution, and (4) the working file's mode would
be produced by co -l. See co(1) for details about -V and
-x. Otherwise, all options of diff(1) that apply to regular
files are accepted, with the same meaning as for diff.
If both _r_e_v_1 and _r_e_v_2 are omitted, rcsdiff 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, rcsdiff 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, rcsdiff 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.
EXAMPLE
The command
rcsdiff f.c
compares the latest revision on the default branch of the
RCS file to the contents of the working file f.c.
