I'm trying to write a program that takes a raw textfile and prints out each sentence in the file on its own line using a regex. I've been able to write the regex to match the sentences, however, the program is reading in the file line by line, and since each sentence in the textfile spans multiple lines, the output is giving me the regex match but it's cut off because the entire sentence isn't all one one line in the original file.

Here's my code so far:

open $fh, $ARGV[0] or die "File $ARGV[0] not found!\n";
while ($line = <$fh>){
    while($line =~ /\s*((((([A-Za-z]|[0-9])*((\'*|\-*)[A-Za-z]*))\s*\.
+*\!*\"*\(*\)*\,*\:*\s*)*(([A-Za-z]|[0-9])*))(\.|\?|\!))/g){
        print "$1\n";

I've tried adding \n* to my regex to make it accept the newline characters in the file, but it doesn't make a difference. I've also tried using m// or /s instead of the /g at the end of my regex, but all that does is give me an infinite loop. I've also tried concatenating the lines together, but I'm very new with perl and it's just not working.
