V7 was released in 1979. If you click on the first link in the article, you get to the wikipedia page on V7, and from there you have a screenshot[1] of what running `ls -l /usr` looked like in a terminal
Two things stand out to me about this screenshot:
1. The output of `ls -l` is very very similar to what my 2021 debian+coreutils produces.
2. The contents of `/usr` are not all that different either! Directories that are common to my system and this screenshot are: games, include, lib, src.

- adrian_b 5y agoUNIX V7 (1979) had more differences compared to the older versions than all the current UNIX descendants have compared to V7. The POSIX standards correspond mostly with V7 with relatively minor additions from the later ATT and BSD UNIX versions. Many of the command line utilities that are still used today have appeared only in V7, e.g. the Bourne shell sh, sed, awk, m4, lex, basename, test, expr. Most command line utilities from V6 or older versions, even those that have the same name as later utilities, may have very different behavior.
