NAME

       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”.
