On my Solaris 10 boxes, I have compressed log files with the ending
gunzip cannot unzip them, however if I change the ending to
.gz, gunzip will unzip them, and these files appear to be empty. So I see the point, however I am not aware of a program that does this. It’s probably a custom script somewhere, however I was not able to find one.
Did anyone ever encounter this file ending? Which program produces this? Google is not helpful here.
