So this is what I have now but it doesn't work. I've tried it manually:
#!/usr/bin/perl
BEGIN {$|=1}
while (<>) {
@X = split;
$url = $X[1];
if ($url =~ /^http:\/\/dnl(.*)kaspersky(.*)com(.*)/) {
print $X[0]."
301:ftp:\/\/dnl-kaspersky\.quimefa\.cu\:2122\/Updates\n";
}
elsif ($url =~ /^http:\/\/(.*)windowsupdate(.*)/) {
print $X[0]." 301:http:\/\/windowsupdate\.quimefa\.cu\:8530\n";
}
else {
print $X[0]."\n";
}
}
it just keeps on returning the same url that I enter. help please?
