Examples
- Merge two changelogs into a new file named
merged.changelog
:
dpkg-mergechangelogs --output=merged.changelog changelog1 changelog2
- Merge only the
Version
andChanges
fields:
dpkg-mergechangelogs --merge-fields=Version:Changes changelog1 changelog2

dpkg-mergechangelogs --reverse changelog2 changelog1
Common Issues
- Incorrect changelog format: Ensure that the changelogs are in the correct Debian format (either 1.0 or 1.1).
- Conflicting changelog entries: If multiple changelogs contain entries for the same version, the entries will be merged and the older ones will be ignored.
Integration
dpkg-mergechangelogs can be used with other commands to automate changelog management tasks. For example, to create a merged changelog and use it to build a Debian package, you can use the following command chain:
git clone https://github.com/example/project.git
cd project
dpkg-mergechangelogs changelog1 changelog2 > merged.changelog
dpkg-buildpackage -S
