service-is-ok 1 user commands nosh service-is-ok svok daemontools compatibility service checker service-is-ok directory svok directory service-is-ok checks to see whether service-manager1 (or runit's runsv1, s6's s6-supervise1, daemontools' supervise1, or daemontools-encore's supervise1) is currently managing a service. directory is either a supervise directory or a daemontools-style service directory with a supervise directory named supervise within it. A service is considered managed if its supervise directory contains an ok FIFO that can be opened for write in non-blocking mode (i.e. client mode). The result is signalled by the exit code, which is 0 upon success, 111 if the directory does not exist or some other error occurred, and 100 if the ok FIFO cannot be opened in client mode. For more on service and supervise directories, see service-manager1. For daemontools and daemontools-encore compatibility, this command is also available as svok. Jonathan de Boyne Pollard
