It's interesting how the home directories were under /usr during that era. If you notice at 13:35, when Brian runs `pwd`, he's at `/usr/bwk` and he says: "that's where I start when I login." Is there any history behind the shift? Or is it just a Linux idiosyncrasy?

That crunchy sound of the VT1xx terminal and the other keyboards in this video are giving me an intense feeling of nostalgia.

I love that video. I’ve seen it 5 times and every time I have to watch the whole thing.

What commands is Kernighan using in his spell checker example? makewords? lowercase? unique? mismatch? Were these really commands in AT&T unix? I kind of suspect that they created some "unique" shell scripts for this video to make it easier to understand..

His full command is:

$ makewords sentence | lowercase | sort | unique | mismatch

I like how back than they called shell scripts "shell sequences"

what were pre-unix file systems like? it sounds like storing bytes in a file in a directory which is a kind of file was innovative, but it's effectively all there is today!

i know old macs had various attributes - e.g. you could store the owner of an file so when you opened it, it would run in the program that generated it, not necessarily the default for files of this type. but is that the alternaitive he had in mind?

Saw that a year back. Thanks ATT for preserving this.

Talk on Unix philosophy, Shell, pipes

Somehow haven't seen this before. Thanks!
