NAME

       ztest - verify integrity of compressed files

SYNOPSIS

       ztest [options] [files]

DESCRIPTION

       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.
