diffpp command examples

diffpp – pretty-print diff outputs with GNU enscript

The easiest way to use diffpp is to use it as an input filter for enscript. If an input filter is specified for enscript it is used to pre-process the incoming data-stream. Filtering does not alter any header strings or file-timestamps which might be printed on enscript headers; only the incoming data is modified.

#enscript -G2re --filter='rcsdiff %s | diffpp %s' *.c *.h

Print the changes between current source files and their latest RCS-versions.

#enscript -G2re --filter='diff %s~ %s | diffpp %s' *.c *.h

Print changes between source files and the corresponding backup-files.
