From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

can anyone help restore back to default?

Thanks!

sudo chmod 755 ~/Downloads

assuming you don't need a recursive solution for subdirectories

[–] tgxn@lemmy.tgxn.net 7 points 11 months ago (2 children)

-R to recurse. Good for chmod and chown

[–] eager_eagle@lemmy.world 11 points 11 months ago (2 children)

useful for chown, less so for chmod: I almost never want my dirs and files with the same permissions, and I made this mistake a few times.

find dir -type f -exec chmod 644 -- {} +
find dir -type d -exec chmod 755 -- {} +

If all you need is to restore read permissions, you could use symbolic rather than octal:

chmod -R a+r $DIR

If you don't want to grant read permissions to everyone you can replace the a with whichever applies of ugo for user, group or other.

Go over it with a second chmod -R but with -X to add execute but only to directories

Don't give all your files execution permissions.

chmod 644 -R Downloads
chmod +x Downloads
[–] tgxn@lemmy.tgxn.net 1 points 11 months ago* (last edited 11 months ago) (1 children)

That's the same as 755, except you are only setting execute on the folder?

[–] possiblylinux127@lemmy.zip 1 points 11 months ago

Why would you want execute on anything but the folder?

I love everything about this screenshot

[–] folkrav@lemmy.ca 59 points 11 months ago (1 children)

The non proportional font on terminal 🤌

[–] pastermil@sh.itjust.works 22 points 11 months ago (2 children)

I think they should use Comic Sans instead.

Webdings

Pretend you're using Ancient Aliens tech

[–] caseyweederman@lemmy.ca 4 points 11 months ago (1 children)

Aptos Mono if you want to feel conflicted

[–] pastermil@sh.itjust.works 3 points 11 months ago (1 children)

That one's at least still fixed width

[–] caseyweederman@lemmy.ca 2 points 11 months ago (1 children)
[–] pastermil@sh.itjust.works 2 points 11 months ago

As long as it's fixed width it's a blessing to me.

Thanks y’all! chmod 755 worked! Back to drwxr-xr-x

[–] RegalPotoo@lemmy.world 33 points 11 months ago

A quick guide to explain what is going on here, and what the numbers mean: https://pbs.twimg.com/media/DaMLUoGXUAI21V6.jpg:large

[–] phx@lemmy.ca 26 points 11 months ago (1 children)

Tip: you can also use chmod u+rwx,g+rx,o+rx etc to add permissions

With the initial letters corresponding to "user", "group" and "other", and (r)was, (w)rite, e(x)ecute for the rest.

In the case of directories, x specifies access to files/etc within the directly (read just let's you see them)

You can also use i.e "o-rw" etc etc to remove existing permissions

[–] lolcatnip@reddthat.com 5 points 11 months ago (1 children)

If you use X instead of x it'll add execution permission to directories without making files executable.

[–] phx@lemmy.ca 1 points 11 months ago

Oh yeah I forgot to mention that. It's important when using wildcards or recursive permissions!

[–] billgamesh@lemmy.ml 23 points 11 months ago (1 children)

I was weirded out by the 12288 filesize. If anyone else is wondering.

So used to seeing 4096 lol

[–] pastermil@sh.itjust.works 1 points 11 months ago (2 children)

Huh, I thought it's a file, but I saw it's a dir. What's up with that odd value?

[–] SaltyIceteaMaker@iusearchlinux.fyi 5 points 11 months ago (1 children)

So how i understood from the link it's that in those 4k all file names in that directory are stored. That space can grow if necessary but won't shrink automatically. So i assume that op has alot of files in that directory

[–] Another_username@lemmy.world 4 points 11 months ago* (last edited 11 months ago) (1 children)

I do have a lot of files in that directory…but music has more files and taking more space. Strange…

[–] billgamesh@lemmy.ml 5 points 11 months ago (1 children)

My reading was it wasn't based purely on number of files, but metadata related to files and stuff (idk what that is in ext4, but movies tend to be large and complex related to music). it's probably irrelevant because that's still a really small number on a modern hard drive.

[–] Another_username@lemmy.world 3 points 11 months ago

Ahh yeah, that makes sense. Thanks for sharing the info!

[–] atzanteol@sh.itjust.works 4 points 11 months ago

I believe directories contain pointers to the nodes under them, so they get bigger with lots of things in them.

[–] bjoern_tantau@swg-empire.de 17 points 11 months ago (1 children)
[–] phorq@lemmy.ml 12 points 11 months ago

If OP did it recursively they would also need -R

chmod 644 -R Downloads
chmod +x Downloads

Your welcome

Edit: I just copied the permissions on the other folders

[–] Another_username@lemmy.world 3 points 11 months ago (1 children)

Downloads should be drwxr-x- -x ?

[–] possiblylinux127@lemmy.zip 3 points 11 months ago

Whoops I misread the screenshot

[–] venji10@feddit.de 2 points 11 months ago

sudo chmod 777 ~/Downloads

As easy as that!
