Package: diffoscope
diffoscopediffoscope 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 was initially started by the “reproducible builds” Debian
project and now being developed as part of the (wider)“Reproducible
Builds” initiative.  It is meant
to be able to quickly understand why two builds of the same package
produce different outputs. diffoscope was previously named debbindiff.See theCOMMAND-LINEEXAMPLESsection further below to get you
started, as well as more detailed explanations of all the command-line
options. The same information is also available in/usr/share/doc/diffoscope/README.rstor similar.Exit statusExit status is 0 if inputs are the same, 1 if different, 2 if trouble.Command-line examplesTo compare two files in-depth and produce an HTML report, run something like:$ bin/diffoscope --html output.html build1.changes build2.changesdiffoscope will exit with 0 if there’s no differences and 1 if there
are.To get all possible options, run:$ bin/diffoscope --helpIf you have enough RAM, you can improve performance by running:$ TMPDIR=/run/shm bin/diffoscope very-big-input-0/ very-big-input-1/By default this allowed to use up half of RAM; for more add something like:tmpfs   /run/shm    tmpfs   size=80%    0   0to your/etc/fstab; seeman mountfor details.External dependenciesdiffoscope requires Python 3 and the following modules available on PyPI:libarchive-c,python-magic.The various comparators rely on external commands being available. To
get a list of them, please run:$ bin/diffoscope --list-toolsContributorsLunar, Reiner Herrmann, Chris Lamb, Mattia Rizzolo, Ximin Luo, Helmut Grohne,
