GZip

If you are using the regular command line gzip, then you would use:

gzip -d filename.gz


If this is a .tar.gz, .tar.Z, .tgz or .taz file, then you should use tar instead.  The tar syntax is:

tar -xvf filename.tar.gz



I hope this helps.  If not, what OS are you using, and what is the full extension of the file?
