Unix Basics - Part 2

Unix's power comes at the price of being a little arcane. With commands like "cd ../.." and "chmod 777 *.sh", it's easy to get confused. But in Part 2 of Unix Basics (Paths and Permissions), we'll show you all the building blocks you need to decipher these commands, and more, step-by-step.

Simple atomic teaching. People can decide wether to take too many info or limitating it.. That chmod command, using numbers was a bit cryptic, but after Jay, things got light in my head... Nice job!

Sure I did enjoy it. Could you do one about programming with Unix? would love that. Thanks again. Unix is cool.

just as good as the first in terms of quality and content covered/explained. it may have been fast in some parts for people who're new to the Unix CLI, but that's why there's pause & rewind buttons :P

Too much was glossed over and it went to fast for me to recommend this to noobs. It felt very rushed. Quality is lacking on this one.

Wow, I just installed linux on a throwaway laptop a friend gave me. This vid made me realize the potential! Thanks! Reminds me of DOS on speed.

For anyone wondering about the 777/755 thing mentioned towards the end of the video:

Values are assigned to the specific states of permissions for an entity as follows: 1 = Execute 2 = Write 3 = Execute + write (1+2) 4 = Read 5 = Execute + read (1+4) 6 = Write + read (2+4) 7 = Execute + write + read (1+2+4)

Values are mapped to: User (owner), Group, Other (everyone), respectively.

So now it should be apparent what 777 and 755 mean in terms of permissions.

This stuff is really basic, but as others said: it's a great reminder. Anyhow I learned some missing details. Keep on typing! Good old Unix needs more followers. :-D

Thanks Jay. Some useful stuff here. Would be nice to have some screenshots or slides so I could soak it in at my own pace, but really very helpful.

Hey Jay, That was awesome and I really like your teaching style. Would love to see you continue with some intermediate tutorials! Thanks!

Great videos. Thanks! Part about permissions is especially awesome :) Would be a bit easier to follow if there were an example set of directories and files provided with the video.
