# diffpp(1)

pretty-print diff outputs with GNU enscript

## NAME

diffpp - pretty-print diff outputs with GNU enscript

## SYNOPSIS

**diffpp *currentfile* \< *diff-file***

## DESCRIPTION

**Diffpp** converts **[diff(1)](/diff/1.md)**-program's output files to a format suitable to be printed with GNU **[enscript(1)](/enscript/1.md)**.  Program annotates the changes with enscript's special escapes so enscript can highlight the modified portions of the file.  All changed and added lines are printed with gray-background, deleted lines are marked with minus (\`-') characters; **diffpp** prints one minus character for each deleted line.

## EXAMPLES

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.
