A ignorant question, suppose i type "fc 89" in a terminal, which will take me into a text editor, after i modify the command, how can i exit the editor and execute the command? Thanks for answering...
On my system, this opens the 'nano' editor. To close out of nano, press 'Ctrl-x'. If you changed your command, then hit 'y' and Enter to save the changes. Once you exit, the command will run.
