       ztest - verify integrity of compressed files


       ztest [options] [files]


       Ztest  verifies  the  integrity  of  the  specified  compressed  files.
       Uncompressed  files  are  ignored.  If  no  files  are  specified,  the
       integrity of compressed data read from standard input is verified. Data
       read from standard input must be all in the same compression format.

       The supported formats are bzip2, gzip, lzip and xz.

       Note that some xz files lack integrity information, and therefore can't
       be verified as reliably as the other formats can.

       Exit  status is 0 if all compressed files verify OK, 1 if environmental
       problems (file not found, invalid flags, I/O errors,  etc),  2  if  any
       compressed file is corrupt or invalid.


       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

              force given format (bz2, gz, lz, xz)

       -N, --no-rcfile
              don't read runtime configuration file

       -q, --quiet
              suppress all messages

       -r, --recursive
              operate recursively on directories

       -v, --verbose
              be verbose (a 2nd -v gives more)

              set compressor and options for bzip2 format

              set compressor and options for gzip format

              set compressor and options for lzip format

              set compressor and options for xz format
