I was planning to use system() to invoke a shell and launch a script. However it appears that this causes the parent process to terminate. A note in Linux Programming Bible (Goerzen, 2000) says to never invoke a shell or use the system() function. Having looked at fork() and exec(), these will require obscene amounts of memory and overhead (for an embedded box). I've also looked at vfork() and execve(), which looks like it will do what I want. So do I do the vfork()/execve() pair, or is there a better way? And would sigaction() handling be the way to pass progress information from the child back to the parent process?
