I first learned Unix when I went to work at Bell Labs in 1978. I was only there for two years but over the next 18 years at Carnegie Mellon I used Unix workstations or time-sharing systems almost constantly. The other night I had a dream that involved Unix. I am not saying the dream made sense. Dreams often don't. For some reason I had a feeling that someone had modified my system by replacing the cat command with a shell script that didn't behave the way cat should. I decided to use the which command to find where the fake cat script was located in the file system. But then I thought how can I examine the script without using cat. I was going around in circles about this until I sort of woke up. I realized that I could use ed to look at the script. Then I went back to sleep. Sometimes my memories of my dreams aren't accurate.
