|
|
.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
|
|
.BI . ext\fR,\fP
|
|
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 Linux places.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-b
|
|
Search only for binaries.
|
|
.TP
|
|
.B \-m
|
|
Search only for manual sections.
|
|
.TP
|
|
.B \-s
|
|
Search only for sources.
|
|
.TP
|
|
.B \-u
|
|
Search for unusual entries. A file is said to be unusual if it does
|
|
not have one entry of each requested type.
|
|
Thus
|
|
.RB ` "whereis\ \ \-m\ \ \-u\ \ *" '
|
|
asks for those files in the current
|
|
directory which have no documentation.
|
|
.TP
|
|
.B \-B
|
|
Change or otherwise limit the places where
|
|
.B whereis
|
|
searches for binaries.
|
|
.TP
|
|
.B \-M
|
|
Change or otherwise limit the places where
|
|
.B whereis
|
|
searches for
|
|
manual sections.
|
|
.TP
|
|
.B \-S
|
|
Change or otherwise limit the places where
|
|
.B whereis
|
|
searches for sources.
|
|
.TP
|
|
.B \-f
|
|
Terminate the last directory list and signals the start of file names,
|
|
and
|
|
.I must
|
|
be used when any of the
|
|
.BR \-B ,
|
|
.BR \-M ,
|
|
or
|
|
.B \-S
|
|
options are used.
|
|
.SH EXAMPLE
|
|
Find all files in
|
|
.B /usr/bin
|
|
which are not documented
|
|
in
|
|
.B /usr/man/man1
|
|
with source in
|
|
.BR /usr/src :

|
|
.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
|
|
.RB ` / '.
|
|
.PP
|
|
.B whereis
|
|
has a hard-coded path, so may not always find what
|
|
you're looking for.
|
|
.SH AVAILABILITY
|
|
The whereis command is part of the util-linux package and is available from
|
|
ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
