$ path /?
Displays or sets a search path for executable files.

PATH [[drive:]path[;...][;%PATH%]
PATH ;

Type PATH ; to clear all search-path settings and direct cmd.exe to search
only in the current directory.
Type PATH without parameters to display the current path.
Including %PATH% in the new path setting causes the old path to be
appended to the new setting.
