Documented steps Create a sandbox: 'from e2b import Sandbox; with Sandbox.create() as s: ...'. Start a background job: 'handle = s.commands.run("python train.py", background=True)' — returns a CommandHandle instead of blocking. Poll/interact via handle methods (e.g. handle.wait()) or later reconnect with 's.commands.connect(pid)'. Enumerate running jobs: 'procs = s.commands.list()'. Stop one: 's.commands.kill(pid)' (sends SIGKILL). Known gotchas Setting background=False makes commands.run block until the process completes. kill() uses SIGKILL, so the process cannot catch it — there is no graceful signal option. A background command's stdout/stderr are only captured once you connect to it / read from its handle. Set timeout=0 on the command if the job may legitimately run longer than the default command timeout.
