In general, each executing process or user session has its own PATH setting. Multics originated the idea of a search path. Once found, the program is executed as a child process of the command shell or program that issued the command. The Windows system directory typically C: Many programs do not appear in the path as they are not designed to be executed from a command window , but rather from a Graphical User Interface.
When a command is entered in a command shell or a system call is made by a program to execute a program, the system first searches the current working directory and then searches the path, examining each directory from left to right, looking for an executable filename that matches the command name given. Other executable filename extensions can be registered with the system as well.
Once a matching executable file is found, the system spawns a new process which runs it. The PATH variable makes it easy to run commonly used programs located in their own folders. If used unwisely, however, the value of the PATH variable can slow down the operating system by searching too many locations, or invalid locations.
Invalid locations can also stop services from running altogether, especially the 'Server' service which is usually a dependency for other services within a Windows Server environment. To find the path the operating system uses to execute a command when you enter it on the command line, use the which command instead, for example:. This is document acec in the Knowledge Base.
