Another way to recall the previous command you can use is to type the double exclamation marks ("!!"). In other words, when you run the double exclamation marks in the terminal, the previous command will be executed. This tip can be quite handy when you want to re-run the previous command as root. For example, instead of re-typing the whole previous command with 'sudo' or 'beesu' before it, you can just type: sudo !! or beesu !!

Sometimes you may want to run multiple commands in the terminal. Here is how to do it:

If you want to run multiple commands in the terminal respectively, just add a semicolon (;) between two commands. For example: command1; command2; command3

With this syntax, it does not matter if a command returns to error, all the commands you use will be executed eventually.

If I double click it I see a choice "run in terminal, view, cancel, run" if I select just "run" sudo command does not execute, if I select "run in terminal" it works fine.

I've installed F17. My network connection and sound card stop working sometimes requiring me to reboot before they work again.
