- 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.
