> The program that uses the inotify system call has to keep a mapping of file descriptors to paths

If it doesn't care what file is modified and just wants to run a command on any change, why would it need to do this?




In that case it's not needed. One could imagine that one would like to start a specific command. That is what 'tup monitor' does.

Another use-case is a desktop search tool.
