Mine just takes an entry from the history list, puts it in a file, runs ex open mode on it, and executes the result. I spent a lot of time fooling with this to get rid of quoting problems and ambiguity. The whole thing is done with the following alias: alias redo 'echo \!*:q > ~/cmd; ex +open ~/cmd; source ~/cmd' It is used as redo !-3 for instance, to edit the third previous command. The following alias is used to get the immediately previous one: alias again 'redo \!-1 ' The only real difficulty is that the command line as stored on the history list aleady has had history substitution performed on it, so it may not be exactly what you typed. There seems no way around this. The one line messages on entrance to and exit from the editor are a minor annoyance, but I don't know a reasonable way to suppress them. Otherwise it works great. One obvious advantage of my system is that the editor is a familiar one -- just vi with a one line window. It's also probably more powerful than any special purpose editor cooked up just for this and requires no separate maintenance. Try it and let me know how you like it.
