comparepdf is a command line application used to compare two PDF files.
       The  default comparison mode is text mode where the text of each corresponding pair of pages is compared.
       As soon as a difference is detected the program terminates with a message (unless  -v0  is  set)  and  an
       indicative return code.
       The   OPTIONS   are   -ct   or  --compare=text  (the  default)  for  text  mode  comparisons  or  -ca  or
       --compare=appearance for visual comparisons (useful if diagrams or other images have changed),  and  -v=1
       or  --verbose=1  for  reporting  differences  (and  saying  nothing  for matching files): use -v=0 for no
       reporting or -v=2 for reporting both different and matching files.
