Linux permissions

Hi everyone,
I’m taking the Linux course. In the section “Security and File Permissions” I have a doubt with the meaning of the last one permission. I understood that the first three meaning Owner, Group and Other. What is the meaning of last one?

Thanks in advance.


That last one is for SUID and SGID , look at this,GID%20of%20file%20group%20owner.

Hi mcortes,

The screenshot you provided shows examples for calculating permission in octal values only.

So each one shows permissions for Owner, Group, and others.

Thanks @Nasri and @KodeKloud
