whereis

NAME

whereis - locate the binary, source, and manual page files for a command

SYNOPSIS

whereis [ -bmsu ] [ -BMS R directory ... -f ] filename ...

DESCRIPTION

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 I . ext, for example, R .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.

OPTIONS

-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 R -B , R -M , or -S options are used.

EXAMPLE

Find all files in /usr/bin which are not documented in /usr/man/man1 with source in R /usr/src :
example% cd /usr/bin
example% whereis -u -M /usr/man/man1 -S /usr/src -f *

FILES

/{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}

SEE ALSO

R chdir (2V)

BUGS

Since whereis uses R chdir (2V) to run faster, pathnames given with the R -M , R -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.

AVAILABILITY

The whereis command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
