rcsdiff(1) MPE/iX Shell and Utilities rcsdiff(1)
NAME
rcsdiff — compare RCS revisions
SYNOPSIS
rcsdiff [–befHhiKkmntwx][–C n][–c[n]] [–Dname][–Ffile...]
[–O][–q][–Rdiff_exec][–rrev1][–rrev2][–Yfile] file ...
DESCRIPTION
Note: The
MPE/iX implementation of this utility does not function exactly as this man page
describes. For details, see the MPE/iX NOTES section at the end of this man page.
rcsdiff compares two revisions of each given file. Files may be either RCS files or working
files. If revisions of a given file are stored in binary format, rcsdiff uses diffb(1) to
determine the differences between the two revisions. If revisions are stored in text format,
rcsdiff uses diff(1).
Options
The options –b, –c, –C, –D, –e, –f, –h, –H, –i, –m, -t, and -w are passed to diffb or
diff. See diffb(1) and diff(1) for the effects of these options.
In addition, rcsdiff supports the following options:
–Ffile...
provides an alternate way to specify file names. The given file is a text file contain-
ing a list of file names, one per line. rcsdiff compares all the files named in file to
their corresponding
RCS files, using the command line options specified. Multiple
–F options may be specified on the command line, and can either be grouped
together or interspersed between options.
–K suppresses keyword expansion and removes all existing expansions. This option
takes precedence over the –k option.
–k suppresses keyword expansion, even if KeywordExpand is specified in the confi-
guration file. This is useful for non-readable binary files such as object files. To
ensure that rcsdiff works properly, you should specify this option for any file that
was checked out with the –k option of co.
–n generates an edit script in the format used by RCS.
–O ignores any default options found in the configuration file.
–q suppresses diagnostic output.
–Rdiff_exec
specifies the path name of the diff command to use. This allows you to use your
own system diff for everything but RCS.
