These commands are useful on linux, if you are an admin, you will defenetly need these. so take notes.

so here we go:
tar is a compression technology used to create a Tape ARchive. The resulting file is known as a tarball. If you are fimiliar with Window, this is the same as a Zip file. You use winzip to compress and uncompress .zip files.So its the same idea. To uncompress the files (or to get the files out of a tarball), you can use the following commands:
tar xvf filename.tar
If the tarball has also been gzipped (compressed), you can use the following command:
tar xvfz filename.tar.gz
If you only want certain directories from the tarball, do this:
tar xvzf filename.tar.gz */dir.you.want/*
If you have a .tar.bz2 file, then you need bzip2 installed (/usr/ports/archivers/bzip2), and you issue this command:
tar yxf filename.tar.bz2
Hope this helps
