- Dot 2 has considered this issue, and the related issue of having a shell
- function of the same name as the desired utility. The "command" utility
- (which was proposed as a shell built-in in earlier drafts, but is a
- stand-alone utility in 1003.2 Draft 11) solves at least part of the problem,
- with no explicit knowledge of directory structure. It relies on the
- existence of a path that is known to make all system utilities (i.e.
- all the utilities specified in Dot 2) accessible. This path is not
- itself specified by Dot 2.
