Hi!

There are actually two errors in your script:
  1. testing a variable doesn't work that way. You have to use test - external or built-in, I don't remember how this is in ksh - hence, I'll show the "old-fashioned way" :-) see your ksh manual page, look for keyword test.
  2. you are using < in your test. for shell, less-than means input redirection from a file
So, this should work:
Code:
    while test $tcount -le 11
    # ... your code here
    done

I also don't quite understand the way incrementation of tcount is done. Simple
Code:
tcount=$(($tcount+1)) would do.

Regards,

pen
