CLI reference / hub app <name>
hub app <name> logs
Follow build and runtime logs.
Show recent output and follow new activity: a build while it runs, then the running app.
While a deploy builds, the logs show the build as it happens, then the output of the app once the new release runs. A deploy that starts later shows up the same way. Lines about the release (building, running, failed) go to stderr, so redirecting stdout keeps the log alone. Press Ctrl-C to stop.
