9.4.1 Invoking pdiff

 
pdiff [options] file-1 file-2 [-- a2ps-options]

Supported options are:

Option: -h
Option: --help
print a short help message and exit successfully.

Option: -V
Option: --version
report the version and exit successfully.

Option: -q
Option: --quiet
Option: --silent
Run silently.

Option: -D
Option: --debug

Option: -w
Option: --words
Look for words differences (default). White space differences are not considered.

Option: -l
Option: --lines

It is possible to give options to a2ps (see section 3.1 Command line options) by specifying them after `--'. For instance
 
pdiff COPYING COPYING.LIB -- -1 -P display

Compares the files `COPYING' and `COPYING.LIB', and prints it on the printer display (usually Ghostview or gv).
