Hi,
In addition to John W. Krahn's good advices:
So far I did this:
#!/usr/bin/perl
use File::Find;
my $totalLines;
find(\wanted, '@directories');
sub wanted {
unless ($_=~m/.html|.mas|.pl|.txt$/i) {return 0;} #filter the

open FILE, $File::Find::name;
Always check if operations succeeded:
open (FILE, '', $File::Find::name)
or die couldn't open $File::Find::name: $!;
Thanks, don't know how I missed that. :-)

I want to know how many new line chars there are in all files in a
directory (and it's subdirectories). What's the best way?
Thanks!

You'll want to use File::Find (a standard module) to do your directory
recursion for you. For each file you get to, open it, count its

I'm sure this isn't how you want to do it, but this might work:
$ cat `find . -type f` | wc -l
It'll choke if you have too

A lot depends on your idea of best. It might be that the
best way is to hand the project off to someone else and reap

Use File::Find to iterate over the files and then sum up the
newlines you find in each file. Counting the newlines in a
single file is
#!/usr/local/bin/perl

# This script executes recursively on subdirs the command you supply as a
parameter

Be careful with this one. The documentation for it makes it sound like
it's a good idea to set this but doing so turns buffering OFF, not ON.
Normally you leave this alone, even for pipes and sockets; Perl does the
right thing in almost every case.
See:
So far I did this:
#!/usr/bin/perl
use File::Find;
my $totalLines;
find(\wanted, '@directories');
sub wanted {
unless ($_=~m/.html|.mas|.pl|.txt$/i) {return 0;} #filter the kinds
of files you want
open FILE, $File::Find::name;
print $_: ;
my @lines=FILE;

That should be followed by these two lines:
use warnings;
use strict;
use File::Find;
my $totalLines;
find(\wanted, '@directories');
Do you actually have a directory in the current directory named '@directories'?
