Re: script timer

["Aranya" <akshata@xxxxxxxxxxxxxxxxxxx>]

The problem in both cases is with using exec. exec doesn't fork, just
changes the current process to the one that is exec'ed. For shell script,
try doing it without exec. For the C program, either fork and exec it, or
simply use the system() call.
