real question is how do you pronounce chmod
shmod. and then cho-wn (ch’own? cho-un?)
and of course, hweel (jk on this one)
c h mod
chmod -R ug+rwX,o=r *
I don’t use chmod nearly often enough to remember these numbers. I know there’s a mathematical way to figure it out, but I cba to do that when u+wrx more or less tells me exactly what it does (grant the User Write, Read, and eXecute permissions)
chmod 755for when setting permissions to directories.chmod +xfor making something executable right when I am about to run it.Chmod 777 I live erratically without consequence.
Nope, +x for life
chmod -R 777 /galaxy brain

Yo dawg, heard you like memes
chmod -R 600 ~/, because I dont trust anyone, not even myself.I forgor the tilde and its taking a long time. wat do
Tilde is a shortcut to /home/palordrolap
sudo rm -rf / --no-preserve-rootStart from scratch
Dont forgot
setfaclI like to chmod it chmod it
But those are different
Had to be done for the joke. :)
Yeah, not only does
+xleave read/write permissions untouched, it also only makes it executable for the user, not for everyone and their cat.Cat doesn’t execute anything tho, it just reads and gives output
Except if you use kitty terminal emulator with unsecure remote access. Issue
Then with cat, you could execute arbitrary commands…
The cat command executes the cat program.
What happens when u try to cat the cat program, is that considered reading or executing
Both, they are not mutually exclusive.
this but in reverse 🤷♀️
u=rwX,g=rX,o=rX because this won’t make every file executable, only folders.
Careful:
chmod -Xalso looks for any existing exec bits:$ umask 0 $ >foo >bar $ ls -al foo bar -rw-rw-rw- 1 user group 0 Sep 10 00:00 bar -rw-rw-rw- 1 user group 0 Sep 10 00:00 foo $ chmod o+x foo $ ls -al foo bar -rw-rw-rw- 1 user group 0 Sep 10 00:00 bar -rw-rw-rwx 1 user group 0 Sep 10 00:00 foo $ chmod u=rwX,g=rX,o=rX foo bar $ ls -al foo bar -rw-r--r-- 1 user group 0 Sep 10 00:00 bar -rwxr-xr-x 1 user group 0 Sep 10 00:00 foo
chmod 666 so only the devil can execute it
