If you get the History Number (i.e. type history) you can change the contents of any previous command by inserting the command number after the first !. As an example if the history command shows that command number 815 is ‘ls -aelF’ and you want to get rid of the e you can type – !815:gs/e//

and ctrl+r is search through command history.

You can use ctrl+a to navigate to the beginning of the line and ctrl+e to the end.

I knew about using the “up arrow” to scroll back through previous commands before, but your “sudo !!” tip is worth the entrance fee alone.

When I think of the number of times I’ve typed a command, forgetting to “sudo” it first and then had to use “up arrow” to show previous command, then tappy-tappy-tappy on “left arrow” to get the cursor back to the start of the line, to put “sudo” in!

Thanks.

You can also use the ^ to replace typos:

$ la bla
-bash: la: command not found
$ ^la^ls
