Here is a useful csh alias which I use to edit my last command. I'm posting it here since others have told me that they have also found it useful. alias ec source ~/bin/ec where ~/bin/ec contains: echo !-1:q > /tmp/ec$$ $EDITOR /tmp/ec$$ cat /tmp/ec$$ eval `cat /tmp/ec$$` rm /tmp/ec$$ The bug is so minor that I'm not even going to try and fix it, however I thought I'd mention it in case someone is making a list (a very big list) of csh bugs. If you use ec to change your command to "history", you get (for example): history 189 set history=4 190 ls 191 ec -1000 ls% The % at the end is your next prompt. I have not been able to duplicate this behavior in any other manner. -- Andrew Draskoy UUCP: {akgua,allegra,cbosgd,ihnp4,mcvax,utcsri}!garfield!andrew CDNNET: andrew@garfield.mun.cdn -- The opinions expressed above may not represent those of the author after he has had some sleep.

Guess what! I made an error in my last posting (it always happens - no doubt this one will have a problem as well.) It seems that the !-1:q should in fact be !-2:q. That's what I get for making last-minute improvements to things that used to work (and for using csh). Also, I have discovered that if you stop your editor session, the csh forgets about sourcing the rest of the file. It looks like this may work better by simply making the alias be: alias ec 'all_the_commands_in_the_script' which is what I had before, and it worked (using !-1:q). If AT&T would release ksh I wouldn't have to worry about this (hint hint). As it is, I will probably end up writing my own shell.
