whereis — locate the binary, source, and manual page files for a command
whereis
[−bmsu
] [ −BMS
directory... −f
] filename...
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 .ext,
for
example, .c
.
Prefixes of s.
resulting from use of source code control are also dealt
with. whereis
then attempts to locate the desired program in a list of
standard Linux places.
−b
Search only for binaries.
−m
Search only for manual sections.
−s
Search only for sources.
−u
Search for unusual entries. A file is said to be unusual if it does not have one entry of each requested type. Thus `whereis −m −u *' asks for those files in the current directory which have no documentation.
−B
Change or otherwise limit the places where whereis searches for binaries.
−M
Change or otherwise limit the places where whereis searches for manual sections.
−S
Change or otherwise limit the places where whereis searches for sources.
−f
Terminate the last directory list and signals the
start of file names, and must be used when any of the
−B
, −M
, or −S
options are used.
Find all files in /usr/bin
which are not documented in /usr/man/man1
with source in /usr/src
:
example% cd /usr/bin example% whereis −u −M /usr/man/man1 −S /usr/src −f *
/{bin,sbin,etc}
/usr/{lib,bin,old,new,local,games,include,etc,src,man,sbin,
X386,TeX,g++-include}
/usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}
Since whereis uses chdir(2V) to run faster,
pathnames given with the −M
, −S
, or −B
must be full; that is, they must
begin with a `/
'.
whereis has a hard-coded path, so may not always find what you're looking for.
