SYNOPSIS SYNOPSIS

DESCRIPTION DESCRIPTION
Ztest verifies the integrity of the specified compressed files. Uncom pressed files are ignored. If a ztest verifies the integrity of the compressed files specified. Uncom pressed files are ignored. If a
file is specified as '-', the integrity of compressed data read from stan dard input is verified. Data file is specified as '-', the integrity of compressed data read from stan dard input is verified. Data
read from standard input must be all in the same compression format. read from standard input must be all in the same compressed format. If a
file fails to decompress, does
not exist, can't be opened, or is a terminal, ztest continues verifying t
he rest of the files. A final
diagnostic is shown at verbosity level 1 or higher if any file fails
the test when testing multiple
files.
If no files are specified, recursive searches examine the current work ing directory, and nonrecursive If no files are specified, recursive searches examine the current working directory, and nonrecursive
