Hi,

I try to print a Unix command output on page with perl.
My script like this:

#!/usr/local/bin/perl

print "Content-type: text/html\n\n";
print "<html>\n";
print "<body>\n";
print "<p><h2>DENEME</h2>\n\n";


@tut=`rsh bcksrv7 mminfo -a|head -20`;
#@tut = system("rsh bcksrv7 mminfo -a|head -20");
#print "<p><h2>@tut</h2>\n";

print "<@tut>";

print "</body></html>";
exit;

but not print the output on page!Help!

Code: 
foreach (@tut) {

}

Try
Code: 
#!/usr/local/bin/perl
use strict;
use warnings;
                                       
print "Content-type: text/html\n\n";             
print "<html>\n";                                
print "<body>\n";                                
print "<p><h2>DENEME</h2>\n\n";                  
                                                 
my @tut = qx[rsh bcksrv7 mminfo -a|head -20];           

print join("<br>\n",@tut), "\n";
print "</body></html>";                          
exit;

I think html doesn't understand the variable.
Because it prints blank.

When you run on the server, does it have authority/permission to run rsh bcksrv7 mminfo -a | head -20? This could account for the empty array.

Good point, Steve. You could try ...
Code: 
@tut=`rsh bcksrv7 mminfo -a|head -20 [red]2>&1[/red]`;
That'll send any error messages to the same place as the normal output ([tt]@tut[/tt], in this case) so you should see them on your HTML page.

Will this capture the STDERR from the first process in the pipe, or from the head? I'm assuming anyone has permission to run head...

Oh! Sorry I was late,

It isn't working Chris.
But I found a different way ;
When I am directing the output to a file then it prints the file.
It doesn't print the variable directly.

Thanks everybody.
