Hi!

There are actually two errors in your script:

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.
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

time

time(1T)						       Tcl Built-In Commands							  time(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       time - Time the execution of a script

SYNOPSIS

       time script ?count?
_________________________________________________________________

DESCRIPTION

       This command will call the Tcl interpreter count times to evaluate script (or once if count isn't specified).  It will then return a string
       of the form
	      503 microseconds per iteration
       which indicates the average amount of time required per iteration, in microseconds.  Time is measured in elapsed time, not CPU time.

EXAMPLE

       Estimate how long it takes for a simple Tcl for loop to count to a thousand:
	      time {
		  for {set i 0} {$i<1000} {incr i} {
		      # empty body
		  }
	      }
