diffoscope

in-depth visual diff tool for files, archives and directories

Description

diffoscope is a visual diff tool that attempts try to get to the bottom of what makes files or directories actually different.

It can recursively unpack archives of many kinds, transforming various binary formats into more human-readable form to compare them in a human-readable way. It can compare two tarballs, ISO images or PDFs just as easily. The differences can be displayed on the console or in a HTML report.
