[tcltk-perl] execute the statement using the "exec ksh -c" in HP UNIX

[M.Srinivasa R. <sri...@in...>]

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/download.csp"
&}

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");
}
--------------------------------------------------

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/download.csp" &}

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/download.csp"
&}

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,
Srinivas.
