Unfragile

The request names GNU's 'which' command, and the only candidate source is the GNU Project documentation index 1, which does not describe the 'which' tool itself; it points to GNU manuals and documentation in general. For the 'which' utility specifically, the GNU Project's documentation pages are the place to look, but this source does not confirm its usage.

A question back: Do you want to know how to use the GNU 'which' command to locate an executable on your system, or are you looking for the GNU Project's general documentation?
