tar is used to create a Tape ARchive. The resulting file is known as a tarball. It's pretty much the same concept as a ZIP file, if you know what they are, but without the compression. To get the files out of a tarball, you can use the following commands:tar xvf something.tarIf the tarball has also been gzipped (compressed), you can use the following command: tar xvfz something.tar.gzIf you only want certain directories from the tarball, do this: tar xvzf something.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 something.tar.bz2 |
