zipcmp —
compare contents of zip archives
  
    | zipcmp | [ -hipqtVv] archive1
      archive2 | 
zipcmp compares the zip archives or directories
  archive1 and archive2 and checks
  if they contain the same files, comparing their names, uncompressed sizes, and
  CRCs. File order and compressed size differences are ignored.
Supported options:
  - -h
- Display a short help message and exit.
- -i
- Compare names ignoring case distinctions.
- -p
- Enable paranoid checks. Compares extra fields and other meta data.
      (Automatically disabled if one of the archives is a directory.)
- -q
- Quiet mode. Compare -v.
- -t
- Test zip files by comparing the contents to their checksums.
- -V
- Display version information and exit.
- -v
- Verbose mode. Print details about differences to stdout. (This is the
      default.)
zipcmp exits 0 if the two archives contain the same
  files, 1 if they differ, and >1 if an error occurred.
zipcmp was added in libzip 0.6.
