The next Two parts will exclusively deal with the Software other than the one's which the Linux distribution, in our case Redhat Linux, may or may not provide as a part of its core distribution. In some cases it may be provided as an extra but may come as pre-compiled binary which may not exactly suit your purpose. Hence we have in most cases used source packages usually packed as tar gzipped -*.tar.gz or in some recent case in tar bzipped -*.tar.bz2 format. This gives us the maximum available choices to tweak, choose and delete the options within these Softwares. Just a word about the *.tar.gz and *.tar.bz2, the contents are same except that the compression used is different and the bz2 extention is smaller in size as compressed format.
