问题
when I download a .tar.gz file, I open it with two commands, first gunzip and then tar.
Is it possible to open it with just one command?
回答1:
tar xzf file.tar.gz
The letters are:
- x - extract
- z - gunzip the input
- f - Read from a file, not stdin
回答2:
You can use tar with a "z" argument
tar xvfz mytar.tar.gz
回答3:
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

How do I extract a gz file?
Use guzip command as follows:
$ gunzip file.gz
OR
$ gzip -d file.gz
How do I extract a tar.gz or .tgz file?
Files with extension tar.gz or .tgz are tar files compressed with gzip. On Unix system extract them with following command:
$ gunzip < file.tar.gz | tar xvf -
$ gunzip < file.tgz | tar xvf -
If you have GNU tar (Linux system) you can use the z option directly:
$ tar xvzf file.tar.gz
$ tar xvzf file.tgz

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

On Windows Try the tartool utility http://tartool.codeplex.com/
Its free and the code is open source and uses SharpZipLib library.
