PROMPT

write a bash script to combine all the necessary included files into a single .fbs file, remove ‘include’ if any of the file contains it, handle includes, handle namespaces, and handle namespaces in each of the files assuming all of them are using same namespace and make it compatible with mac without adding additional ; in namespace

Sent by you: assume i have file3.fbs include file1.fbs, file2.fbs. what is the flatbuffer command to get all combined.fbs  that parses and embed all the necessary included files definition in it

Sent by you: since flatc cant do that, can you write an bash to do that?

Sent by you: do you see the prb? your for will only copy all the contents, it wont remove "include" if any of the file contains it

Sent by you: No worries! Can you provide an updated script that handles includes?

Sent by you: what about the namespaces in each of the files?

Sent by you: assume all of them are using same namespace
