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".
