# debpatch(1)

Applies a patch to recreate a debian package.

## NAME

debpatch - Applies a patch to recreate a debian package.

## SYNOPSIS

**debpatch** \[*OPTION*\]... *DELTA FROMFILE* *TOFILE* \
 **debpatch** \[*OPTION*\]... *DELTA /* *TOFILE* \
 **debpatch** **--info** *PATCH*

## DESCRIPTION

This program is designed to apply a patch (DELTA) to a Debian package (FROMFILE) and create the Debian package (TOFILE). If the Debian package (FROMFILE) was installed in the host system and the .deb file is not available, then the argument (FROMFILE) may be  substituted by the keyword / : then debpatch will get the needed data from the host filesystem.

- **-v**

  **verbose (can be added multiple times).**

- **-d**

  **print full traceback on Python errors; save useful info in temporary files**  **in case that a delta fails.**

- **-k**
