How to change folder permissions with sudo?

Question

linux

Good afternoon.

There is ssh access, tell me how to change the rights for a certain folder through sudo, since the folders were not made by me and I cannot change the rights. Respectively edit and upload files too.

I used this command: chmod -R ug+rw srv/test/

Answer 1

Sometimes it is enough to google

Answer 2

sudo chmod

Answer 3

FOR EXAMPLE sudo chmod -R 777 the folder name //-R is a recursion (the same rights are given to everything nested in this folder).
777 is a combination of permission bits:
read (R=4)
write (W=2)
and execute (X=1)
4+2+1 =7
Why is 7 not one but 3 at once?
The first 7 allows all these actions for a specific user, the second seven for a group of users, and the third for other users. Arbitrary combinations of these parameters are possible, for example 755, 744, 111, etc. Also, sometimes an additional symbol is put in these parameters - stickybit.
Before giving exactly FULL rights (777) to a folder, you need to think very carefully.
