I'm trying to implement a utility that will backup and restore Oracle database files using unix shell scripts for test databases. However to ensure the file permissions are retained they must be run as Oracle user. This is OK for development of the scripts, but for general use I'd hoped to set the suid on these scripts owned by Oracle and allow users to perform these tasks while ensuring traceability as each user uses a unique log on. However because of the security problems associated with suid on shell scripts my version of unix doesn't allow this facility to work. The solution I envisaged was to write a thin wrapper to each unix script, written in C and then set the SUID of the resulting executable. My question is, how do I invoke unix shell scripts from within my C program ? Many thanks for reading this far !
Thanks in advance for any assistance

See man-pages for system() fork() and exec() Regards Rainer

A bit off topic, but you can download the C source for such a beast from:
