I have some files with 755 and I need to change them to 750, but I am not sure if this can affect some process.

I am changing JARs, XMLs, LOGs, and properties files.

Can someone explain to me the difference between these two permission sets?

Thanks!

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

  • User - means the account user (admin or other added user) in the machine - what's the difference between `Group` and `World`? – Tom Taylor Dec 18 '17 at 13:31

    "user" means the account user. Group would mean other people in a defined "group" of users (like members of a group, "lab256" say, would be able to have `r-w` access. World would mean anyone else that can log in to that particular machine. – AruniRC Jan 29 '18 at 19:15
