I created a cron in unix that fires off a perl script which in turn calls a 'c' program. The problem is that I need the 'c' program to finish before the script continues on. I first tried exec() but the perl script terminated without continuing when the 'c' program was finished. Then I tried "$command = expect->spawn('c_program');" but it seems the perl script continues without waiting for the 'c' program to finish. Any help would be appreciated.

Hello kevhart,
'sounds like you need to use 'system'. It will spawn the child process and wait for it to complete and return the exist status of the child process.
Do, 'perldoc -f system' for more details.
Use it like this.....
@args = ("command","arg1","arg2"
;
$cmd_exit_status = (system(@args))/256;
HTH
keep the rudder amid ship and beware the odd typo
