<kmc> addquote <kmc> i had a dream just now where i was in a gymnasium and they had fire alarm pull stations but they also had a similarly shaped "call/cc alarm" which I think you were supposed to pull if you found a way to write call/cc (it was expected that people in this gymnasium would be doing a lot of programming in total dependently-typed languages)

#!/bin/sh
topic=$(echo "$1" | tr A-Z a-z | sed "s/ *$//")
topic1=$(echo "$topic" | sed "s/s$//")
cd wisdom
if [ \( "$topic" = "ngevd" \) -a \( -e ngevd \) ];
    then cat /dev/urandom;
    elif [ -e "$topic" ];
    then cat "$topic";
    elif [ -e "$topic1" ];
    then cat "$topic1";
    else echo "$1? ¯\(°_o)/¯"; exit 1;
