In the end the real answer is that to me it's simpler, less typing,
solves the problem but mostly because *I like awk*. :-)
BTW... Awk is used so much on a system that most likely it is already
in ram and is probably not as heavy of a system impact as you imply.

Yes.

This isn't a bug. It just means that the termcap/terminfo entry doesn't provide the right entries that allow the key sequences output by the arrow keys to be bound to the motion commands you want. You can do this yourself; the easiest way to find out the key sequence output by an arrow key is to use `cat -v'. Chet -- ``The lyf so short, the craft so long to lerne.'' - Chaucer Live Strong.

I am just so used to using process redirection to solve the old "but my variables don't maintain their value after my " | while read $var; do string="$string $var"; done" problem that I immediately think of process redirection. Of course instead of "<(cat $file)" I could have just used "$file". What would be funny is if bash pointed one to the above URL when it detected one doing something silly like that. b. -- My other computer is your Microsoft Windows server. Brian J.

I don't think I was even considering the disk read time to load it. I think I was purely considering the cost of fork/exec. In any case, dead horses and all. b. -- My other computer is your Microsoft Windows server. Brian J.
