i don't know if anyone can help, but i've posted all my code so that it might help. I'm trying to find emails in a file, my problem is, it works for all the different formats that i've specified BUT it only works if all the emails are on seperate lines, as soon as i have multiple emails on the same line in the text file, it "might" find the first occurence (it usually does) but the rest of the emails on that line are ignored, this is my code, i hope someone can help: 
#open the 2 files for input and the second for output
open (FIN, "@ARGV[0]") || (die "No input file");

while(<FIN>){
        if(s#((\b\w*\b\s)(\b\w*\b\s)?(\b\w*\b\s)(\<)(\b\w*((\.)?(\w*)?
+)*[@]\w*\.\w*((\.)?(\w*)?)*\b)(\>))# $1 .($var =$2.$3.$4."\t".$6) #eg
+){}
        elsif(s#((\b\w*\b)(\,\s)(\b\w*\b\s)(\b\w*\b\s)?((\<)(\b\w*((\.
+)?(\w*)?)*[@]\w*\.\w*((\.)?(\w*)?)*\b)(\>)))# $1.($var = $4.$5.$2."\t
+".$8) #eg){}
        elsif(s#((\")(\b\w*\b\s)(\b\w*\b\s)?(\b\w*\b)(\")(\s)(\<)(\b\w
+*((\.)?(\w*)?)*[@]\w*\.\w*((\.)?(\w*)?)*\b)(\>))# $1.($var =$3.$4.$5.
+"\t".$9) #eg){}
        elsif(s#((\")(\b\w*\b)(\,\s)(\b\w*\b)(\s\b\w*\b)?(\")(\s)((\<)
+(\b\w*((\.)?(\w*)?)*[@]\w*\.\w*((\.)?(\w*)?)*\b)(\>)))# $1.($var = $5
+." ".$6.$3."\t".$11) #eg){}
        elsif(s#((\")(\b\w*\b\s)(\b\w*\b\s)?(\b\w*\b)(\")(\s)(\[)(\b\w
+*((\.)?(\w*)?)*[@]\w*\.\w*((\.)?(\w*)?)*\b)(\]))# $1.($var =$3.$4.$5.
+"\t".$9) #eg){}
        elsif(s#((\")(\b\w*\b)(\,\s)(\b\w*\b)(\s\b\w*\b)?(\")(\s)((\[)

#hash my emails        
$hashed{$var}++;

#print out all the emails
