NAME
       ztest - verify integrity of compressed files

SYNOPSIS
       ztest [options] [files]

DESCRIPTION
       Ztest verifies the integrity of the specified compressed files.	Uncom‐
       pressed 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.

OPTIONS
       -h, --help
	      display this help and exit

       -V, --version
	      output version information and exit

       -M, --format=<list>

       -O, --force-format=<fmt>
	      force given format (bz2, gz, lz, xz)

       -q, --quiet
	      suppress all messages

       -r, --recursive
	      operate recursively on directories

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