While you could use channels directly, the cockpit.spawn() API works well for this: https://cockpit-project.org/guide/latest/cockpit-spawn.html Something like this: process = cockpit.spawn(["/path/to/script"], err: "message"); process.fail(function(ex) { /* invoked if script fails */ }); process.stream(function(data) { /* invoked for every block of data script write to stdout */ }); Use this option to include stderr output in the streamed output: err: "out" If the script expects input or EOF on stdin, you can send it using: process.input("data"); or process.input(""); ... respectively.
