diffoscope — in-depth comparison of files, archives, and directories

Synopsis

diffoscope [-h] [--version] [--debug] [--html output] [--text output] [--max-report-size bytes] [--css url] file1 file2

Description

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 and was formerly known as “debbindiff”.
