Problem remaining :-( Your code work for perl "print" only but no for
external programs or external program use non standard routines for
output. Please try this part of code
print "<html><body>";
open( FH, '>out' ) or die;
*ORIG = *STDOUT;
*STDOUT = *FH;
system('echo hallo');
*STDOUT = *ORIG;
print "<br>System command was be run</body></html>";
in server script and "run" this in browser eg.
http://somedomain.com/cgi-bin/myscript.pl
You will see
hallo
System command was be run
Maybe not on Linux but on MS-IIS yes :-)
I resolve my problem with this trick
print "<span style=\"display: none\;\">";
system('echo hallo');
print "</span>";
Output from external program still go to browser but for user is not
visible. Have you a better idea?
