Ok. Unix nerds. Tell me your most obscure, interesting, or downright weird abuse of pipes. Bonus points for using tee and named pipes. Please if possible give the whole command (redact file names if necessary).
I'm teaching some people about what you can do on the UNIX command line and I need more examples.
@quixoticgeek I don't have the code, but I know people used to create a live email footer with a named pipe called .footer or something that was fed using a 'quote of the day' program (probably just a script that fed from an array of quotes)
Who uses footers anymore in email?
