Interesting, cidaris. But have you ever used the join command?

It would save you your loop on "while(@other_builds)". 

$command_line = "c:\\execu $first_build "; # note trailing space
$command_line .= join " ", @other_builds;
$command_line .= " file.c";

The only downside here is that you wind up with 2 spaces between $first_build and file.c if there are no other_builds.

The problem goes away if you do everything in a join: 

$command_line .= join " ", ("c:\\execu $first_build",@other_builds,"fi
+le.c");
