File Permissions for Linux

When we look at the file with Ls-l,

Will find something like this.

Rwxrwxr-x

Something like that, yes, that's the file's permissions.

Let's start with the first one.

RWX, what do you mean, the first one seems to represent the user, the second rwx seems to be the delegate, the user group, and the third delegate is the other user

R, the delegate is readable

W, Representative is writable

X, which represents an executable

RWX, the delegate is a readable and writable executable

More details, Baidu a bit ~
