So I don’t personally, fully understand this command, however another weird situation has happened in my life of living with a programmer. Randall exclaimed at the computer again. His friend messaged me online to let me know what kind of trouble Randall was in. It turns out my husband, Randall, accidentally locked himself out of his own application by typing the wrong command. Thanks to Craig for letting me know(uh, Randall says that you distracted him and it’s your fault he ran this command!). 😀
