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.

Thanks!

sudo chmod 755 ~/Downloads

assuming you don't need a recursive solution for subdirectories

[–] bitchkat 8 points 11 months ago (2 children)

Sudo is completely unnecessary here. If the owner changed, use chown first reset the user. Then use chmod to change permissions.

You’re correct…sudo wasn’t necessary

[–] eager_eagle 1 points 11 months ago (1 children)

that's probably right, though sudo will work every time

[–] dohpaz42 5 points 11 months ago (1 children)

You should only use elevated privileges only when you need to. Otherwise you risk catastrophic failure.

No I did not use "sudo rm -rf /*". How did you know?

[–] bushvin 4 points 11 months ago (1 children)

Dude! That’s just plain wrong!

If you wanter do remove the French language packs, you should have run

sudo rm -fr /*

-R to recurse. Good for chmod and chown

[–] eager_eagle 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

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

[–] [email protected] 1 points 11 months ago

Why would you want execute on anything but the folder?
