Change Name after gzip
 

I know the default gzip file is .gz , for example , if gzip a file "test.txt" , then the zipped file name is "test.txt.gz" , if I want to change the extension of zipped to "test.txt.oc" , except use mv after gzip , can advise what can I do ? thx

well you can use the -S option to override the default extension if you really want to.

You can choose the suffix with option -S, e.g.
but if you try to gunzip a file with extension .oc, gzip is not able to recognize it and you have to rename again!

Edit: sorry for repetition! I did not see the answer from acid_kewpie before posting.
