       rcsdiff - compare RCS revisions

SYNOPSIS    [Toc]    [Back]

       rcsdiff  [-ksubst]  [-q]  [-rrev1  [-rrev2]] [-Vn] [-xsuffixes]
 [diff options] file...

DESCRIPTION    [Toc]    [Back]

       rcsdiff runs diff(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 ci(1).

       The  option -q suppresses diagnostic output. Zero, one, or
       two revisions may be specified with -r. The option -ksubst
       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  substitution,
  -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  rev1  and rev2 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  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    [Toc]    [Back]

       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.

ENVIRONMENT    [Toc]    [Back]

       options prepended  to  the  argument  list,  separated  by
       spaces.  See ci(1) for details.

DIAGNOSTICS    [Toc]    [Back]

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