Today I learned:

`/usr` stands for “universal system resources” not “user”

`/dev` stands for “device” not “development”

Had no idea.

I knew about dev, but usr i always thought was user

@SanitizedOutput beat me to it, gee, when do I get to be smart?

Oh you got me there,never knew both of them. I really thought usr was user.

What is the thing with those abbrev? Is there a technical reason why you couldn't write device, not dev? Or was that just lazy

@GodlikeBlock same dude

Wondering why they named it dev instead of device.

/tmp stands for temporary, not trump.

@Ekushey
/Trump is where I store all my bitcoins 😉

Interesting, I didn't know about /usr yet. But personally I would classify universal resources more as a /etc thing, given that all the configuration files reside there. Unix isn't very well-known for its intuitive naming so I guess it makes sense 🤔

/usr and /usr/bin in particular seem much more like a /bin equivalent to be nowadays (which it kind of is, /usr/bin is often a symlink to /bin).

@david-hil
Back in the day, the longer your file/folder names were, the less space you had for your files. Keep in mind that these were back in the days when MB were considered huge.

@iamavalos @ocaiquemello

It was actually backronymed. Originally /usr was for user directories. When programs got bigger they moved from /bin to /usr/bin (which was on a different, bigger disk) which caused the home folder to be moved.

The more you know

This Twitter thread does a great job of explaining

I always thought usr stood for UNIX system resources

@SanitizedOutput "originally"
That'd make more sense tbh, but I guess /home works too...

Looks like I learned that too today

I knew usr byt not dev

Wow I learned something today thanks

Learning never ends

Wtf? That is mind blowing

Is it?

Is worth to mention that in the past, in larger networks, the usr was mounted as shared resource over the network.

Wait... what

@GodlikeBlock same here

@SanitizedOutput ok, I knew my users were there when I was using Linux. Top comment had me judging my memory. About to be a Mandela effect up in here.

@Trithon couple years late, but same, lol

Also, "pwd" stands for "print working directory", not "password".

Oh, I know what "pwd" means. It's "password"!
