whereis is a command on Unix and Unix-like operating systems used to locate some special files of a command like the binary file, source and manual page files. The whereis utility was first included with 2BSD, dating back to 1979.
Syntax.
The codice_1 man page provides the following sample usage:
% # Find all files in /usr/bin which are not documented in /usr/man/man1 with source in /usr/src:
% cd /usr/bin
% whereis -u -M /usr/man/man1 -S /usr/src -f *
Analogs.
The Unix codice_2 command is similar, but it identifies aliases.
Modern versions of Microsoft Windows feature a similar command: codice_3.
It's also similar to the codice_3 utility in Multics.
