-b     Search only for binaries.

-m     Search only for manual sections.

-s     Search only for sources.

-u     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.

-B     Change or otherwise limit the places where whereis searches for binaries.

-M     Change or otherwise limit the places where whereis searches for manual sections.

-S     Change or otherwise limit the places where whereis searches for sources.

-f     Terminate the last directory list and signals the start of file names, and must be used  when  any
       of the -B, -M, or -S options are used.
