I am not looking for a fix i.e the corrected commands and their locations. No !!
OK, now i am a bit baffled. In my experience the best error handling is the one where you dn't have to handle anything at all because you avoid the error altogether. Only the next best is to report the error properly.

This is quite easy: any responsible script programming includes checking the return codes of all the commands (at least the vital ones). This return code will be non-zero for:
a) - failing commands, regardless of why they fail, but there will be different error codes for the error condition
a1) - unknown argument/option
a2) - not enough rights
a3) - whatever else the error might be
b) - unknown commands
In case of b) the shell itself will return error 127, as you can easily test with a known and an unknown command:
You should be able to build an error handling function around that.
