# polybar-msg
> Control `polybar` using inter-process-messaging (IPC).
> Note: IPC is disabled by default and can be enabled by setting `enable-ipc = true` in the Polybar config.
> More information: <https://polybar.rtfd.io/en/stable/user/ipc.html>.
- Quit the bar:
`polybar-msg cmd quit`
- Restart the bar in-place:
`polybar-msg cmd restart`
- Hide the bar (does nothing if the bar is already hidden):
`polybar-msg cmd hide`
- Show the bar again (does nothing if the bar is not hidden):
`polybar-msg cmd show`
- Toggle between hidden/visible:
