  • otherwise the shell might hose you.
    • Might? With that broken join I’d say it’s a certainty that at some point the shell will hose him. Plus it’s less and simpler code:

      BEGIN {
          if(! $ENV{LD_LIBRARY_PATH} ) {
              $ENV{LD_LIBRARY_PATH} = join(':', @some_paths_I_need);
              system($^X, $0, @ARGV);

      Also: why system(...); exit and not exec?

      • Just out of curiousity, why is that join broken?

        Also, I didn't use exec because I didn't know how the security restrictions around LD_LIBRARY_PATH were enforced. Using exec means the process continues to have the same pid, system gives me an entirely new process. I wasn't sure if having the same pid would allow me to do what I wanted to do.

        But thanks for the clarification. It works correctly (at least on the Linux machine I tried it on).
