Can gunzip detect a bad Z file?
For pack, gunzipchecks the uncompressed length. The standard compressformat was not designed to allow consistency checks. However gunzipis sometimes able to detect a bad .Z file. If you get an error when uncompressing a .Z file, do not assume that the .Z file is correct simply because the standard uncompressdoes not complain.
