How to split a config file into several in linux?

Question

linux

gentlemen, how to expand the config file in Linux? For example, there is /etc/exports, what should I write in it to take rules from /etc/my_exports ?

Answer 1

in the general case - not at all
if the program that reads the config can do this - it will be said in its documentation.
in this case see man exports
Extra Export Tables
After reading /etc/exports exportfs reads files in the /etc/exports.d
directory as extra export tables. Only files ending in .exports are
considered. Files beginning with a dot are ignored. The format for
extra export tables is the same as /etc/exports
