.SH DESCRIPTION
|
|
.B whereis
|
|
locates source/binary and manuals sections for specified
|
|
files.
|
|
The supplied names are first stripped of leading pathname components
|
|
and any (single) trailing extension of the form
|
|
.BR .ext ,
|
|
for example,
|
|
.BR .c .
|
|
Prefixes of
|
|
.B s.
|
|
resulting from use of source code control are also dealt with.
|
|
.B whereis
|
|
then attempts to locate the desired program in
|
|
a list of standard places:
|
|
.RS
|
|
.nf

.B "whereis -m -u *"
|
|
asks for those files in the current
|
|
directory which have no documentation.

.SH BUGS
|
|
Since
|
|
.B whereis
|
|
uses
|
|
.BR chdir (2V)
|
|
to run faster, pathnames given with the
|
|
.BR \-M ,
|
|
.BR \-S ,
|
|
or
|
|
.B \-B
|
|
must be full; that is, they must begin with a
|
|
.BR / .
