Re: file merge problem

[injunjoel]

Greetings,
Just a thought.

#!/usr/bin/perl -w
use strict;
my %d = map{
        /^(\w+) /; 
        $1, $_;
    }grep{
        chomp;
        /^\w+ \d+/;
    }map{
        local @ARGV = ($_);
        <>;
    }<F*.dat>;
open(MRG, ">merge.dat") or die "Oops! There was a problem: $!";
print MRG, $d{$_}."\n" for(sort keys %d);
close MRG;

This assumes your input filenames match the pattern "F*.dat" for the glob to work on.

Updates

Thanks jdporter for the lower map suggestion. Much cleaner. Way better than the if(open (IN, $_)){#stuff} I was using.
