Done in that way, there is no difference: exec will start a shell, just as system does.

What the OP wants is:

  • fork, then in the child process:
  • open the output file and attach it to STDOUT
  • exec with the list of parameters (it will not invoke a shell)
  • meanwhile, in the parent process, you can wait for the child to finish

For more info, you can look at "perlipc" and the "fork" entry in "perlfunc"

Most of my code is tested...

Perl is strongly typed, it just has very few types (Dan)
