No it won't.

Have you tried it?

That code was for tcsh but from the csh manual page you'll see that backticks are used for Command Substitution. As I sit here using tcsh day after day at work I think I know what this assignment will do....

ZB-
Sorry I didn't mean to imply you didn't know what you're talking about, but I did try it and it is not working as expected. If I do an echo $j it will spit out
echo "$i" | sed "s/$1/$2/"

Is it possible that I have something set that is different from what you are running?

No probs Smilie

I think I see the problem....

I didn't use code tags and maybe the backticks look like single quotes if you haven't copied and pasted directly....

Code:
set j = `echo "$i" | sed "s/$1/$2/"`

Cheers

Ok, yes I am not cutting and pasting, I have am on my PC now but the code is on my UNIX box. As I said before, I only write these things when I need them so I had no idea that ' is different from `
