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 whereis 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 type command is similar, but it identifies aliases.
Modern versions of Microsoft Windows feature a similar command: where.
It's also similar to the where utility in Multics.
