Ok, thanks, I wrote this based on your suggestions, and it seems to do what
I want. One further question, if you don't mind, how to format this so that
it prints sizes in megabytes, not in bits?
---code---
#!/bin/perl
use warnings;
use strict;
use File::Find;
my $dir = $ARGV[0];
die "You must supply a full directory path" unless (-e $dir && -d $dir);
opendir (DIR, $dir) or die "can't opendir $dir: $!";
my $total_size_of_files_in_dir;
while (defined(my $directory = readdir(DIR))) {
next if $directory =~ /^\.\.?$/;
next if -f $directory;
find(\&wanted, $dir);
print "The total size of the file in $directory is
$total_size_of_files_in_dir bytes\n";
}
sub wanted {
if (-f $_) {
$total_size_of_files_in_dir += -s;
}
}
---code---
