internal¶

Starts, stops, restarts and displays the state of the internal services of a scandir.

Interface¶

internal [ -h ] [ -o owner ] start|stop|restart|status fdholderd|oneshotd|eventd

The internal services fdholderd, oneshotd and eventd belong to every scandir: 66-scandir starts them before any other service at its first scan. This command acts on one of them, or displays their state.

A stop lasts until the scandir is started again, which brings every internal service back up.

This command expects an already running scandir for the relevant owner, and exits with 100 otherwise. The start, stop and restart subcommands wait for the internal service to reach its state for the time given by the -T option of 66, without limit by default.

Options¶

-h, --help: print this help.
-o, --owner owner: operate on the internal services of the given owner's scandir. Only the root user can use this option.

Subcommands¶

start: start the internal service.
stop: stop the internal service.
restart: restart the internal service.
status: display the state of the internal service, or of the three in the order fdholderd, oneshotd, eventd when none is given. Each line holds the name of the internal service followed by the state line of 66 status: the state, the pid when it runs, the time since the state changed and who changed it. The state reads None when no supervisor of the internal service runs. It sends nothing and waits for nothing: the -T option of 66 has no effect. It exits 0 whatever the state of the internal services.

Usage examples¶

Restart the event daemon of the current owner's scandir

66 internal restart eventd

Stop the oneshot daemon of owner's scandir

66 internal -o owner stop oneshotd

Display the state of the internal services of the current owner's scandir

66 internal status
fdholderd : up (pid 16) since 2min 3s by self
oneshotd  : down since 5s by user
eventd    : up (pid 45) since 2min 3s by self
