The next thing we need to do might seem counterintuitive, but background the shell with Control-Z. Next, we will upgrade to a fully functional shell with a little Linux fu. python -c 'import that is a little better, but we still don't have tab completion or command history, and if we hit Control-C it will still exit the session. ![]() Then, it spawns a bash shell, and after we hit Enter, we should see a real prompt. The pty module offers pseudo-terminal abilities to the shell, which is useful for some commands that require a terminal environment to run. In this case, it first imports the pty module. Below, the -c flag specifies the command to run. Now we can use this to spawn a proper bash shell.

With a little command-line magic, we can get around this limitation, though, and come out on top with a fully functional interactive shell. It can be infuriating, especially if there were a lot of steps to get that shell. Let's say you run a command, and it hangs, and you instinctively hit Control-C to cancel it. Perhaps the most annoying thing that can happen (I'm sure it's happened to many of you) is accidentally losing your session by hitting the wrong keys.
