Create a completion for particular instance of a shell command, regardless of how it is called (via absolute or relative path), but not others which may share the same name, but be located elsewhere. For instance, you might want completion for a script located at ~/bin/example.sh, but not /usr/bin/example.sh.

Q. I author/maintain package X and would like to maintain my own completion code for this package. Where should I put it to be sure that interactive bash shells will find it and source it?

A. Install it in one of the directories pointed to by bash-completion's pkgconfig file variables. There are two alternatives:

The recommended directory is completionsdir, which you can get with
 pkg-config --variable=completionsdir bash-completion. From this directory, 
 completions are automatically loaded on demand based on invoked commands' names,
 so be sure to name your completion file accordingly, and to include (for example) symbolic links
 in case the file provides completions for more than one command.
The other directory (which only present for backwards compatibility) is compatdir
 (get it with pkg-config --variable=compatdir bash-completion) from which files are loaded when
 bash_completion is loaded.
