Full Discussion: While loop with limit counter

When I try your script with || changed to &&:
Code:
#!/bin/ksh

c=0
while [[ ! -f /tmp/unex && $c -lt 10 ]]; do 
    echo /tmp/unex NOT found, iter : $c;
    ((c = $c + 1));
    sleep 2; 
done

(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?
