Hi Ryan,
You could try the Unix shell compiler at
http://www.datsi.fi.upm.es/~frosal/ which doesn't actually compile the
shell script but generates C and then the standard C compiler does the
rest. maybe write in shell with mv's and compile to C and see if it
looks efficient?
hope this helps

If you want the C program and the spawned shell script to
interact and communicate back and forth with each other,
then you'd have to use the pipe() system call to set up a
two-way interprocess-communication pipe in the C program,
then call fork() to spawn a new identical process
(including the
fork() and exec() are what you're looking for. I haven't done it in a
while, but you should be able to find plenty of info online.

If it is just a simple script call use system(/home/me/myscript);
Be careful, your env vars might not be what you expect them to be.

have to redirect the output to a new file and do a 'mv' to rename it back.
with the filepointer, I was hoping to be to use fopen in C to open the
