You are not testing the existence of a file $i, but whether $i is a file with length zero.

For testing, whether $i is a plain file, use -f instead of ! -s

Hi rovf,
Please look at rajrishi990's code above more closely. The loop variable i is not referenced at all inside the loop. One file specified by the first command line argument (if there was one) is checked 5 times. And, of course, if there was no command line argument given to this script, it will run tokesn.ksh five times as quickly as it can no matter what tokesn.ksh does. Smilie

You might have noted that in post #6 in this thread, I asked:
Quote:
What operand are you passing to that script when you invoke it? Does the file named by that operand exist? If it does exist, how big is it?
and we have not yet seen an answer to those questions.

Oops! It seems to be $1 (digit one) in the code. I misread it as $i (letter i). They look so similar....
