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.
