I am trying to open a file, and search for a srting. Once found I want to substitute it for something else and acually change the file. ie) File named "stuff.txt" contains: Code: ( text ) Hello I am Kelly Hello I am David Hello I am mark I want to find David and change it to Josh. This is how I am trying to do it, but it doesn't work. 
open (FIL, "+<stuff.txt") or die "$!";
 
foreach $line (<FIL>){
 
if($line =~ m/David/){
$line =~ s/David/Josh/;
}
print $line;
}

What am I doing wrong? I tried opening the file with ">>" and "+>>", to no avail. ???
