diffoscope
diffoscope will try to get to the bottom of what makes files or directories different. It will recursively unpack archives of many kinds and transform various binary formats into more human readable form to compare them. It can compare two tarballs, ISO images, or PDF just as easily.
It can be scripted through error codes, and a report can be produced with the detected differences. The report can be text or HTML. When no type of report has been selected, diffoscope defaults to write a text report on the standard output.
diffoscope is developed as part of the “reproducible builds” Debian project. It is meant to be able to quickly understand why two builds of the same package produce different outputs. diffoscope was previously named debbindiff.
Example
To compare two files in-depth and produce an HTML report, run something like:
$ bin/diffoscope --html output.html build1.changes build2.changes
diffoscope will exit with 0 if there’s no differences and 1 if there are.
diffoscope can also compare non-existent files:
$ bin/diffoscope /nonexistent archive.zip
To get all possible options, run:
$ bin/diffoscope --help
External dependencies
diffoscope requires Python 3 and the following modules available on PyPI: libarchive-c, python-magic.
Optionally, the following modules will enhance it:
tlsh is used to recognize file renames. It is build from tlsh source. Available on Debian as python3-tlsh.
python-debian is used to inspect Debian control files. It is available on PyPI.
rpm-python is used to inspect RPM files. It is built from rpm. Available on Debian and Fedora as python3-rpm.
Magic-file-extension can be used instead of python-magic. It is built from file. Available on Debian and Fedora as python3-magic.
The various comparators rely on external commands being available. To get a list of them, please run:
$ bin/diffoscope --list-tools
