I had download some tar.gz files. I was looking how can I decompress them but i've seen lots of ways. I would like to know which ones are the basic differences between them..

These are some examples:

- gunzip -i xxxx.tar.gx | xvf
- tar xvzf xxxx.tar.gz

And some other like those.. Now I dont remember specifically, i'd written them from my mind,

Please somebody help me.... What Should I do after those steps.?

Sometimes there is an "install", "make" etc....

Read the INSTALL or README file that is tar'ed with them and it should give instructions in most cases to install. Other than that, it all depends on the package your installing.

Well here is how I usually deal with tar.gz files. However, I am also a noob so there are probably better ways. I will use the tar command on the tar.gz as follows " tar xzvf <filename.tar.gz>" x - extract, z - unzip, v - verbose, f - filename. After that you will have a directory created similar to the filename you used tar with. Now you can cd into that directory and most likely run ./configure to set up the make file and such. You will also want ot read the readme and install files in this directory because this should tell you how to go about installing the app. After ./configure completes sucessfully you will run "make", then su to superuser and run "make install". This should install it and get it up and going, but refer to the readme and install because some apps are different. Hope this helps!

On another note, unless its something I've installed before, I always read the INSTALL or README files so I can assure myself I'm installing it properly, instead of assuming its just a basic:

tar -xzvf packagename
cd packagename
./configure
make
su - root
make install
make clean
exit

./runpackage
