hi friendz,
can anyone tell me wat is the difference between tar and gz? y is tar used for? n after creating tar file, is it a compulsion to gzip it? does tar compress a file? n in linux most of the files rather applications are with ".tar.gz" extension....i am totally confused between tar and gz ......n can i ftp a tar file? plz help me......
Well, the tar file is an archive that contains all the files you packed into it. It does not compress anything. It just stores the files in one "container"-file. What you do with gzip is compress this container-file. That's why it is called .tar.gz. It is a tar file (.tar) that is compressed with gzip (.gz) or bzip2 (.bz2).
It's as simple as putting a few things (the files) into a box (the tar archive) and putting the hole box into a shrinker (gzip).
