NAME
whereis - locate source, binary, and/or manual for program
SYNOPSIS
whereis [-b] [-B dir] [-f] [-m] [-M dir] [-s] [-S dir] [-u]
name ...
DESCRIPTION
whereis locates source/binary and manuals sections for
specified files. The supplied names are first stripped of
leading pathname components and standard extensions for
source files and manual entries, e.g., .c and .1m. 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 places. If any of the -b, -s,
or -m flags are given then whereis searches only for
binaries, sources, or manual sections respectively (or any
two thereof). The -u flag may be used to 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.
Finally, the -B, -M, and -S flags may be used to change or
otherwise limit the places where whereis searches. The -f
file flags is used to terminate the last such directory list
and signal the start of file names.
EXAMPLE
The following finds all the files in /usr/bin which are not
documented in /usr/man/man1 with source in /usr/src/cmd:
cd /usr/ucb
whereis -u -M /usr/man/man1 -S /usr/src/cmd -f *
FILES
/usr/bin/whereis
/usr/src/*
/usr/{doc,man}/*
/lib /etc /usr/{lib,bin,old,new,local} Since the program
uses chdir(2) to run faster, pathnames given with the -M,
-S, and -B must be full; i.e., they must begin with a /.
