RCSDIFF(1-SVR4)     RISC/os Reference Manual      RCSDIFF(1-SVR4)



NAME
     rcsdiff - compare RCS revisions

SYNOPSIS
     rcsdiff [ -biwt ] [ -cefhn ] [ -rrev1 ] [ -rrev2 ] file ...

DESCRIPTION
     rcsdiff runs diff(1) to compare two revisions of each RCS
     file given.  A file name ending in ',v' is an RCS file name,
     otherwise a working file name. rcsdiff derives the working
     file name from the RCS file name and vice versa, as
     explained in co(1). Pairs consisting of both an RCS and a
     working file name may also be specified.

     All options except -r have the same effect as described in
     diff(1).

     If both rev1 and rev2 are omitted, rcsdiff compares the
     latest revision on the trunk with the contents of the
     corresponding working file. This is useful for determining
     what you changed since the last checkin.

     If rev1 is given, but rev2 is omitted, rcsdiff compares
     revision rev1 of the RCS file with the contents of the
     corresponding working file.

     If both rev1 and rev2 are given, rcsdiff compares revisions
     rev1 and rev2 of the RCS file.

     Both rev1 and rev2 may be given numerically or symbolically.

EXAMPLES
     The command

             rcsdiff  f.c

     runs diff on the latest trunk revision of RCS file f.c,v
     and the contents of working file f.c.
