SL(1): Learn the muscle-memory to send SIGQUIT all the time

Part of this tool’s “charm” is that it traps SIGINT so you truly are forced to watch the animation as a punishment for bad typing, even if you try to send it SIGINT from your keyboard by typing control-C.

Control-backslash sends SIGQUIT on the other hand. This signal cannot be trapped.

Perhaps sl could launch a parent process and a child process, put the child in a different process group, then restart the child if the parent sees it do a core dump?

Or launch two children — one of them daemonized — where the daemon attaches a new sl to your terminal if it sees its sibling one die prematurely. You could still get back to an interactive shell with the right signal but sl would keep annoying you by drawing a train over the top.

Yes, it can.

Indeed. The only signals that cannot be caught (or blocked, or ignored) are SIGKILL and SIGSTOP.
