xvzf command not found

edit

...to uncompress the tar file i used xvzf utorrent-server-3.0-25053.tar.gz command it shows xvzf not found...

xvzf are options for the tar command which is the correct one in order to uncompress any tar file. If the tar file is also compressed with the .gz extension(gzip) then you will need the option z to uncompress it correctly. What these options mean ?

x = uncompress - extract.

v = be verbose - show what you are doing.

z = use the .gz(gzip) filtering while uncompress the file.

f = use this file - the file that is following the command.

The correct command is

tar xvzf <archivefile.tar.gz>
