The other day I was snooping around using gzip to see if gzipping a file, and then gzipping it again would actually cause it to be compressed twice. I used the following command on the solaris machine:
/usr/bin/gzip -qfS.ryangz /tmp/taco
As a result, I was left with a /tmp/taco.ryangz file that was compressed. Now if I run the same exact command on the new file:
/usr/bin/gzip -qfS.ryangz /tmp/taco.ryangz
The taco.ryangz stays the same! Now if I was smart I wouldn’t have done the -q option and saw the message saying that the file was unchanged because it already had the .ryangz suffix. Oh well, some things are more obvious that others sometimes.
