Got perl?
#!/usr/bin/perl
if($#ARGV < 1) {
print "Arguments: <file1> <file2>\n";
exit(1);
}
open(FIRSTFILE, $ARGV[0]);
open(SECONDFILE, $ARGV[1]);
@first = <FIRSTFILE>;
@second = <SECONDFILE>;
$i = 0;
for($i = 0;$i < 2; $i++) {
$tmp1 = $first[$i];
$tmp1 =~ s/\n//g;
$tmp2 = $second[$i];
$tmp2 =~ s/\n//g;
$str = $tmp1 . "\t" . $tmp2 . "\n";
print $str;
}
close(FIRSTFILE);
close(SECONDFILE);
