You probably encuntered the case where a package was not installed and the system was recommending you to install it using apt-get install mypackage.

I am looking for a quick keyboard shortcut for executing this last line. Obviously UP arrow would not bring it because it was not a command executed by you and only the last output line of the previous executed program.

Any ideas on how to get this behaviour in bash?

By default the output isn't "stored" anywhere. You might be able to hack together a solution… see here: automatically capture output of last executed command into a variable –  slhck Nov 23 '13 at 8:04

@MariusMatutiae that's what I did for years, but it requires me to switch from keys to pointing device select, copy, click, paste, clearly a "complex" process. Maybe I will endup implementing a shortcut my in the terminal (iTerm2). –  sorin Nov 24 '13 at 15:36
