When I run the code below, the $ENV{'HTTP_USER_AGENT'} is coming up blank, I'm saved the file under .pl and .cgi extensions and still I can't display the browser name.
For this reason the code below goes straight to the else statement, In actual fact I'm using IE.
Where I'm I going wrong? - #!/usr/bin/perl
-
-
print "Content-type:text/html\n\n";
-
print "<html><head><title>Welcome</title></head>\n";
-
print"<body>\n";
-
print "Browser: $ENV{'HTTP_USER_AGENT'}<p>\n"; # $ENV is blank here!!
-
-
if ($ENV{'HTTP_USER_AGENT'}=~/MSIE/) {
-
print "Your using <b>IE</b><p>\n";
-
} elsif ($ENV{'HTTP_USER_AGENT'}=~/Mozilla/) {
-
print "Your using <b>Netscape!</b><p>\n";
-
} else {
-
print "Your using a browser other than IE & Mozilla\n";
-
}
-
-
print "</body></html>\n";

Print out all your environment variables and see what they contain. Maybe it's a casing problem. -
#!/usr/bin/perl -wT
-
# Print a formatted listof all the environment variables
-
-
use strict;
-
-
print "Content-type: text/html\n\n";
-
-
foreach my $key (sort keys %ENV) {
-
print "<p><b>$key</b><br>";
-
print $ENV{$key};
-
}

All the environmental variables are printing as normal such as Homepath, processor_identifier, OS etc.
However there is no 'HTTP_USER_AGENT' in the list of Environmental variables.
I can vouch that it doesn't print that variable on my Windows machine or my Solaris box either. I think that this script needs to be run through Apache to get that environment variable. Actually, do you have Apache running on this system? It would probably set that variable.

I have Apache is running successfully and still I get the problem.
It may be that this script would need to be run via a web page to determine what browser is accessing the site. It may not be something that works via the command line. (Yes, I am just speculating here, considering the variable is not set).

Jeff
Resolved now, the problem was due to the Shebang line not pointing to the perl.exe and also I didn't know the URL to run the script locally, the URL to run the script locally is: http://localhost/cgi-bin/browser.cgi
Thanks Numberwhun for your help.
Cheers
Your welcome, glad we could all help.

Jeff
