I am migrating tcl/tk application from Hp Unix to windows.one of tcl/tk script contain following line of statement.

    -command {exec ksh -c "$path/startexp.pl  http://www.perl.com/down
+load.csp" &}
[download]

I am calling the tcl scripts using the perl in windows as well as unix.

startexp.pl contain the following code.
-------------------------------

$url = ARGV[0];
if (win32) { 

    system("iexplore $url");
} elseif (hpunix)

    system("mozilla $url");
}
[download]

--------------------------------------------------
1) In windows I am able to open the url using the statement given below .

    -command {exec cmd  /c "$path/startexp.pl  http://www.perl.com/dow
+nload.csp" &}
[download]

2) In unix I am not able to get the url which I am passing along with startexp.pl

    -command {exec ksh -c "$path/startexp.pl  http://www.perl.com/down
+load.csp" &}
[download]

I am not able to find the reason why I could not url when running in unix.

The way I am calling is correct or not?
In unix shall I use ksh -c when script calling using perl.
Is there any alternative to ksh -c ?

Please suggest and help me towards this.

With Regards,
mathi
