You must be knowing where you have downloaded the Kopete Tarball.
What you have to do is cd (change directory) to the place you have downloaded Kopete.
Using the cd command is simple.
Code:
user@computer$ cd /directorytowhichyouhavedownloadedkopete/
For example, if I have it in my /home/user directory,
Code:
user@computer$ cd /home/user/kopete
Note here that I have the Kopete Tarball in the folder called KOpete.
The Linux Shell supports Tab completing mechanism.
So, just press tab, and it will tell you all possible options you can enter.
