In 2023, most Unix systems are actually running some version of Linux, which includes modern tools and commands that were unthinkable when Unix hit the scene in the early 1970s. But some 50 years later, “Unix” still lives on. I wanted to look back on Unix history and experience first-hand what it was like to use the original Unix. Unix 3rd Edition debuted in 1973, and I chose that version as my target. That’s transporting back in time by 50 years. 6:20 terminal setup 9:20 FORTRAN66 program 16:30 nroff document 32:20 linenum program For another example of using Linux like original Unix, read my article on Sysadmin Signal: https://sysadminsignal.com/2023/06/19/run-linux-like-original-unix/ For more FreeDOS content, visit our website https://www.freedos.org/ Join us on Facebook https://www.facebook.com/groups/freedosproject/ Follow us on Mastodon https://fosstodon.org/@freedosproject Consider supporting me on Patreon https://www.patreon.com/freedos And don't forget to Like and Subscribe!
