Essential CVS

Name

rdiff — Synonyms: pa, patch

Synopsis

cvs [cvs-options] rdiff [-flR] [-c|-u] [-s|-t] {-r revision|-D date} 
[-r revision2 | -D date2] [-V version] projects...

Creates output that can be redirected into a file and used with the GNU (or equivalent) patch program. The output goes to the standard output (stdout). rdiff operates directly from the repository and does not need to be used from a sandbox. It does require a filename, directory name, or module name as an argument, and you must specify one or two revisions or dates. If you specify one revision or date, rdiff calculates the differences between that date and the current (HEAD) revision. If two dates are specified, rdiff calculates the differences between the two.

See also diff.

Tip

Most people use rdiff to make a file to use with patch. If you’re using a patch file that was created over more than one directory, you may need to use the -p option to patch, so it can find all the appropriate directories.

Command options

-c

Use context output format, with three lines of context around each change. This is the default format.

-D date

Display the differences between the current sandbox copy of a file and the latest revision as of the date or time specified by date.

-f

Use the latest (HEAD) revision of a file on the current branch or trunk if no revision matches the date or revision number. This option applies only if -r or -D is used.

-l

Run rdiff on files in the local directory only. (Do not recurse down subdirectories.)
