In bash I can use
!! to indicate the last command. In ksh I think you can use
r to do something similar, but it seems to fail in one of my common patterns: typing
sudo [last command].
> cp foo /bar cp: permission denied > r c # If I do this it will repeat my cp call > sudo r c # when I do this, it tells me that "r" is not a command
How can I use history to quickly type "sudo [last command]"?
