perl file handles - GoFuckYourself.com

I enjoy learning perl in my spare time and I am having a hard time trying to figure out how to open a file and match each line agaisnt a $variable. For example if the variable was a name and the file contained 500 names and I wanted to see if the variable name matched any in the file. Anyone know what I talking about?

What something like....

$VARIABLE1 = "SOMETEST";
open (WORDLIST, "wordlist.txt");
@RAWWORDS= &lt WORDLIST&gt ;
close (WORDLIST);

foreach $LINE (@RAWWORDS) {
chop $LINE;
if ($LINE = $VARIABLE1) {
print "Match with $LINE \n";
}
}

F'ing display parser on the board! Take the spacing
out on the less than symbol on the 3rd line where we dump
the contents of a file into the array.

500 lines for an array isn't bad, don't do this method
for 10000+ lines unless you've got some time to waste.

I'm tired and I've fought with the parser, milage may
vary! This should be what you want for a quick and
dirty. If it doesn't work check the web from here.

Cheers!
