I've got the extraction options for tgz files pretty well ingrained in my brain, but whenever I had to create an archive I always had to go back to the manual.

Not any more! Annoyed at my terrible memory I created a little mnemonic for myself. Here's the command in question:

tar -czvf FILENAME.tgz FOLDER

And to remember the params I've got this nifty sentence:

Tar Can Zip Very Fast

I guess it should be gZip for accuracy, but hey it works for me ;)
