Linux gurus, how do I set a directory to be read only for all users? using chmod?

is it chmod 666?

Or chmod 744?

444

I don't want any user to do anything except READ in a directory.

Thank you, I knew it was something, I couldn't remember.

rm -rf /

4 is read. 2 is write and 1 is execute.

Tired of users messing with files I want to be read only.

Thanks for the help, greatly appreciated.

Thanks, been a long time since I used the chmod command and forgot what the numbers were. I do know that 777 is everything.

This is some real guru level stuff, so it's good you came to the Linux guru forum so everyone can show you how will they know the benchide chmod octals.

Obviously, you could have looked this up faster than you could create the thread.

But then we couldn't tell you how cool you are for using Linux and needing to make a directory read only using chmod.

We also do .htaccess lol

Well, I was in a hurry and didn't want to look it up. I guess I was lazy :)

"you do not have the required permission"

try again

I like you .

I guess I need to brush up on my chmod command and learn the numbers :)

Run it as root or sudo.

Um, that command would destroy the entire O/S if you were logged in as root!

dude , he's trying to get you to delete your harddrive .

Similar to Del *.* /a

I'm not THAT stupid!

I know that.

Do you really think I am THAT stupid? That would delete everything on the hard drive!

Is always good to set the root password and let only ONE person know it, that way if the system is ever completely deleted, you know who did it. I am the only one that knows the root password, and it is very secure. NEVER give anyone the root access password.

I once heard a story about someone being fired from their job and set up a cron job to run 30 days later after they were terminated to run rm -rf / * as root, which destroys the entire file system including the O/S itself.

I remember that.like three years ago.a member on here.

Last I heard they had to rebuild the entire server.

Word of advice, NEVER piss off a network administrator of fire them.
