There is also Samhain/Beltane which is a host-based intrusion detection system too. IMHO it doesn't make much sense to try to program somthing in shell code what someone has already written in a higher programming language as a complete and mature package.

Shell code has its limitations, it was never intended as an application programming device and it is only fit for this purpose up to a point.

There is a way to do what you want on a rather low level: intercept the respective system calls (fopen(), etc.) and build these interceptions into a library, then use this library as PRELOAD. You might want to compare with "Snoopylogger" which uses this same method to intercept execve() calls. As feasible as such a method would be it will not be possible to do it in shell at all, though.

I hope this helps.
