A totally revamped whereis(1), bringing back all the functionality of
the 4.3BSD command. Rewritten from scratch after the old man page, taking account for the different situation with man pages and source tree hierarchy (re: /usr/src/gnu) of the FreeBSD project. Reviewed by: wosch (actually loooong time ago)

|
The search for sources is implemented as a quick search as the
|
||||||
|
first-level subdirectory of each element of the list of source
|
||||||
|
directories first. If this didn't succeed, the utility
|
||||||
|
.Xr locate 1
|
||||||
|
is requested to do the search in deeper nested subdirectories. This
|
||||||
|
might take some time, and will only succeed if the locate database is
|
||||||
|
up-to-date.
