In this code i am having a hard time matching "a+b" as an argument. If i insert "a\\+b" as an argument it works. I am wondering if there is another way around this so that it works with "a+b" as an argument. 

use strict;

my $var1 = $ARGV[0];  
print $var1."\n";

open(IN, "temp.mine") or die "Error opening temp.mine\n";
while(<IN>) {
    my $line = $_;
          print "input = $line\n";        
    if($line =~ /$var1/m) {
        print "found \n";
        close(IN) or die "Error closing file\n";
        exit 0;
    }
}

close(IN) or die "Error closing temp.mine\n";
print "not found  \n";


#contents of file temp.mine
#a+b

i am working on a larger program where i am having an error due to the above problem. Please if anyone knows a way i can match this without changing my input argument or the temp.mine file let me know asap. Thanks Waris
