The documentation for bash says: PROMPT_COMMAND If set, the value is executed as a command prior to issuing each primary prompt. It is not triggered when the current working directory changes. It is triggered every time a prompt is printed. This is such a small amount of cpu time that it is probably not worth the effort to make it only happen when the directory changes.
