Opening a .tar.gz file with a single command

The only thing that I would add is that z usually only works on gnu tar. The typical UNIX tar won't have this in my experience at least. – Jon Mar 16 at 16:19

The z option works well on my OS X v10.5 (Leopard) as well.

When it comes to memorizing, I think it´s easy to think of what you want and not just some letters.

  1. If you want to create an archive, then c will be the first option, else x will be the first option if you want to extract.
  2. If you want to compress/decompress with the gzip/gunzip program, then the next option should be z for zip. (All archives ending with .gz must be unzipped with the z option)
  3. The last mandatory option is f for the file.

Then you usually end up with these two commands:

  • tar czf file.tar.gz /folder_to_archive/*
  • tar xzf file.tar.gz

tar xzf file.tar.gz

The letters are:

  • x - extract
  • z - gunzip the input
  • f - Read from a file, not stdin

You can use tar with a "z" argument

tar xvfz mytar.tar.gz

If you don't have gnu tar it is still possible to open the file in a single step (although technically still two commands) using a pipe

zcat file.tar.gz |tar x
