Thanks. Thats what I suspected. Is it the shell that expands the * or
is it the command? I guestimate would be the shell is expanding it. :)

I was able to get grep to fail, it took a few more hundred files.
Choked on the same thing. The find command is working tho..
I ran a tail on 6000 files (3 to 4 lines) and it worked.
I should of ran it after the grep failed. The files are gone now, but
there is always next run in a few days. :)

Would you know how to get rid of that annoying 80 col line limit in ksh.
I've been searching and searching, asking anyone technical enough to
know. Just when we think we have it, nope. I looked at a lot of the
stty options compared Linux to the SGI and Solaris machines we run.
What happens: prompt here> command xxxx x xxx (once you hit 80
characters, it shifts the line to the prompt like a type writer, no line
wrap. When you go to edit, you get $ >xxxx xxxx xxx xxx[ ]
when you move back, you get $ >xx[ ] x xxx xxx xxx*
It gets worse as the prompt grows, I often end up using PS="$" to get
some typing room or for editing, because the PS variable is so limited
in ksh. Sux... oh well..

Sorry I cannot release the filenames, but it should be easy to
reproduce, with a for next loop. Create about 7000 or so files with
filename length of 17 characters. x(13).x(3)

Thanks. It did. Have a good one. :)
Thanks again for replying so quickly.
