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”.
