Hi Yogesh, You can also change suid through perl, but following options are also possible through perl which will do the job for you - (1) Configure suidperl on the system which recognizes the ownership of the file and assigns owner's permissions to access the system. (2) Above mentioned functionality is also provided by cgiwrap in a more secure manner as compared to suidperl. (3) changing UID is also possible through some perl functions. You may need to look at these functions through which you can change the ownership of operation.
