NAME

whereis - locate source, binary, and or manual for program

SYNOPSIS

whereis [ -sbm ] [ -u ] [ -SBM dir ... -f ] name ...

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 ``.ext'', e.g. ``.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 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/src/*
/usr/{doc,man}/*
/lib, /etc, /usr/{lib,bin,ucb,old,new,local}

BUGS

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 ``/''.
