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.
