Sl: a steam locomotive in your terminal

Re: Sl: a steam locomotive in your terminal
#42When a colleague accidentally types their password to our cluster into a chat window, the first thing I do is login as them and alias ls=sl. Another fun one is to add `telnet towel.blinkenlights.nl` to their .bashrc, so on login they get to watch ascii star wars.
It warms my heart to see that towel.blinkenlights.nl is still up.

erm, no? "while true; sl; done"
zsh: suspended while true; do sl; done

^Z will just suspend `sl`, at which point bash will immediately launch another copy. That's what the loop is for.
Have you actually tried it? In neither zsh nor bash does this seem to actually be the case.

Well no, because I didn't want to install `sl`.
But it looks like you're right. I just tried `while true; do ( echo hi; sleep 1; echo bye; ); done` and ^Z does stop the cycle.

#46If you're on a Mac with homebrew, "brew install sl" will get you there!

Interestingly, at least how I have zsh configured and don't have bash configured, the behavior of `fg` after suspending these is different.
With zsh when I resume the execution it continues looping. However with bash it resumes for only one more iteration.

... and if you unset telnet's escape char, they will watch it to the end.
That's hilariously evil

Yeah I would have expected `fg` to continue the loop, but it doesn't. If I put `echo $?` after the subshell in that loop, it doesn't even print when I run `fg`. It's like bash just throws away the loop entirely when I suspend the subshell.
