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/share/man/man1 with source in /usr/src/cmd:

cd /usr/ucb
whereis −u −M /usr/share/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 “/”.
