I have some questions about some Terminal commands:
Why must you do
sudo apt-get updatebefore installing an program or after downloading something? Does it update Ubuntu then?
What is the different between
sudo gedit /location/to/afile.txtand
gksu gedit /location/to/afile.txt?
Why people don't use
-yon the end of a command, like for example in
sudo apt-get install programx -y.
What does the
-l(are there any more) mean in a Terminal?
How can I unpack any .zip or .tar.gz file in a Terminal?
