cagebreak-socket(7)

NAME

cagebreak-socket Cagebreak socket

SYNOPSIS

ipc-socket-capable-tool $CAGEBREAK_SOCKET

DESCRIPTION

The cagebreak socket is an ipc socket.

The socket is enabled if cagebreak is invoked with the `-e` flag.

The socket accepts cagebreak commands as input (see cagebreak-config(5) for more information).

Events are provided as output as specified in this man page.

  EVENTS

Events have a general structure as follows:

    "cg-ipc"json object depending on the eventNULL

Here is an example of how this works using only as a command sent over the socket.
