    ive watched many tutorials already and youre the first one to show the command 'man' …thank you so much! googling linux issues always leads to nowhere for me…

  • Amazing instructor

  • How do read the file after it is in a directory, my file is test.txt running cat test.txt after putting it in my directory gives an error

  • not bad

  • This looks like DOS 2.0 or does Des DOS 2.0 look like this?

    rm -rf / would make a great t-shirt

  • Dave, I am David. David's are the best. Thank you for your videos

  • What's with the black square on the video?

  • now I know that if you'll ever be my interviewer, that I'll only need to say that Deus Ex is the best game ever made and I'll get hired

  • thanks by the way-this stuff is gold

  • quick (probably stupid) question; why would you need to 'ignore nonexistant files'?

  • Where do I get the Virtual Machine of the Linux you're using?

  • Deus Ex the Original first one is the best.. JC Denton Approuve that and screw Unatco

  • hahah YES. deus ex. got so many people interested in technology and linux, 🙂 JC, there asking for you out in Hong Kong, you NEED to do this mission and DONT MESS IT UP hah. good times..

  • So far, every single person that does these tutorials that I've looked at refers to the Terminal as the "Command Line". Such confusion (especially for Windows users), but here's the clarity:

    Terminal is literally a program window into the CLI, or "Command Line Interface", which can be any number of different login shells, including the most common one, BASH (Bourne Again SHell).

    In all technicality, these terms ARE NOT interchangeable in testing for Linux +, etc. so please be aware of the distinction.

  • lol "man man" -universe breaks

    rm -rf –no-preserve-root /

    Your poor keyboard LMFAO!

  • Thanks man

  • Hmm. The first three seconds gave me the urge to install Deus Ex again, which I had to resist. As they say: every time you mention it, someone reinstalls it.
