How To Use Shell Environment Variables

Title should be “Environment Variable for 8years olds…” it’s actually that CLEAR !!! Thanks, man.

You are very good and decently detailed with you presentations. How many years will it take a newbie to get to your level?

love the explaination, why can't people keep videos nice and simple like this.

thank you Very Much

love the T-Shirt

Thanks

thank youuuu

I just realized you have /home/dt/.local/bin in your path twice

THANK YOU!

shell-color-scripts: local (1.0.r52.3dbdfac-1) is newer than AUR (1.0.r39.143937f-1) getting this how do you fix it?

Can you please use timestamps on your videos? thanks

What is a Hindu Goddess doing on your t-shirt ?

PS: Nice video!

Thanks

Hey DT, how do you colourize your ls command?

Thx. for doing great job on this channel. Currently I'm migrating back to Linux. Currently I'm struggeling to set up my printer (ET-3750). But I guess it's just a matter of setting the right permissions or the right environment variables.....

Your channel is doing a great job bringing me back up to speed!

You have an extra /home/dt/.local/bin in your $PATH just fyi...

Hello, i just watched you video about irssi, and do you know some chat program like this one? but safety and privacy... Or batter, maybe could you teach how create a chat between two computer? wait, a better topic, if you know could you please make a video about cryptography, and the asymmetric cryptography, and the most important, how to apply the asymmetric, because for example , I know about it, but I don't really know how to use it, how to implement and so on and so forth. Or maybe anyone who is reading this comment could please send me a video or a site or a book about it please

do you have any dotfiles for the specific qtile or something else I think window manger setup?

I don't have mouseface. not in repo. I found it in Github. Can someone please tell me the command to download it. The Github-clueless among us would appreciate it. I do have fortune though. The first time I tried it I got this : Q: How many existentialists does it take to screw in a light bulb? A: Two. One to screw it in and one to observe how the light bulb itself symbolizes a single incandescent beacon of reality in a netherworld of endless absurdity reaching out to a maudlin cosmos of nothingness.

👍

I disable $HISTFILE when debugging in Codium

it is 32767 because it uses 16 bits to store

Sorry DT but there are actual definitions for concepts of local and global variable, and that's not it. Since you're being (for a good reason!) followed by total newbies, you really shouldn't be playing it fast and loose. Oher people may at a later point need to un-teach incorrect concepts before they can learn correct ones; and that's a bi*ch job.

BTW I use fish

btw have u tried river? a tiling window manager for wayland?

32767 is the maximum number you can represent with 15 bits. I don't know why they used 15 bits for it, though.

do a video on hannah montana linux

I keep on learning 😊

Why if I put my envs in zprofile or zshenv system doesn't see they? For example sxhkd can't use it.

That print on his T-shirt is of religious Goddess in Hinduism...

hey dt!, i have a question, how can i make the dtos installer?, like when you launch dtos installer it is a GUI INSIDE TERMINAL LIKE NCURSES HOW CAN I DO THAT?

Thats a 'KALI' on his t-shirt

$ p='Hello. '

$ echo $p
Hello,

$ p+='world!'

$echo $p

Hello, world!

Wow DT. Your lighting is getting better and better

Hey DT, the range 32767 is int with size 2 (byte). So for a variable defined with integer size 2 can store -32768 to 32767. Thanks for the videos.

can someone explain the difference between ~ and $HOME. When should you use one over the other?

Is it goddess Kali maa in your tshirt

Bro can you make a video on how we can setup our own cross platform terminal that can run all the commands of bash and cmd it will be really cool if you could make a video on this topic.

Why would someone use a sub shell?

Awesome content DT cheers from Spain

The PATH stuff was getting to me. I have been wanting to dig deeper into this but never did. Your short and sweet description on how to add paths was a Godsend!

Great video! Thanks for the education.

Like a script-kiddie, I was just copy/pasting the line: PATH="$HOME/Applications:$PATH" (changing "Applications" to whatever I needed to add) without fully understanding the simple syntax. Now I do. This means worlds to me!

I also agree that a playlist of these UNIX/Linux/POSIX commands would be great to help find them all.

Thank u. I thought installing arch would be really hard ; but your previous tutorial videos had really taught me a lot about that

Actually, Environment variables are defined in the process that run any program, not just Shells.
And in Bash, and other Shells, there are variables in the Shell (Bash has both local and global variables in the Shell).
Environment variables are the ones in the process.
The Good thing is that Environment variables are copyed to the child process. Then the parent process can't change them for the child process.
And No process can change any other process Environment variables. Not even the patents.

MS Dos have global Environment variables, so any process can change any other programs Environment variables. Which is bad.

You're looking lean bro. Great video.

Wow! your T-Shirt is so awesome 😃

I need this info in a cheat sheet, i forget it everytime i need it, as long as its in Bash, it never changes

Niceee!
👏👏👏

Daniel: echo $VAR
The cooler Daniel: printenv VAR
