SL(1): Cure your bad habit of mistyping

“Any time - any time - you type any remotely incorrect command, the interpreter creatively resolves it into rm -rf / and wipes your hard drive.”

```

function command_not_found_handler() { figlet "lol, $1" }

```

(I think the bash equivalent is `command_not_found_handle`).

This overrides the function that usually prints the `zsh: command not found: foo` message, and instead, mocks you, by printing "lol, foo" (but in big ol' figlet letters).

SL is in a similar, but admittedly much more elaborate, spirit.

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.

It was the thing that prompted me to learn tmux so I could switch tabs without needing multiple putty windows.

The original use case went away long back, but I use tmux still, so thanks I guess :)

But then I realized, I rarely ever do `ls` itself - it's always either `ll` = alias for `ls -lh` or `la` = alias for `ll -A`. And those seem less typo prone, somehow.
