(note that ksh is in /bin instead of /usr/bin on my system) and the file /tmp/unex does not exist; I get the output:
Code:
/tmp/unex NOT found, iter : 0
/tmp/unex NOT found, iter : 1
/tmp/unex NOT found, iter : 2
/tmp/unex NOT found, iter : 3
/tmp/unex NOT found, iter : 4
/tmp/unex NOT found, iter : 5
/tmp/unex NOT found, iter : 6
/tmp/unex NOT found, iter : 7
/tmp/unex NOT found, iter : 8
/tmp/unex NOT found, iter : 9

and it then quits. Isn't that what you want?
oh yes, thank you so much
