10.10.: chmod, file mode bits

Asked by peter on 2011-06-02

Hello

Where can I find a line-up of the file mode bits which I can use by chmod?

Example: chmod 777 /tmp
chmod 440 /etc/sudoers

Where are 777 or 440 described? Thanks in advance.
Peter

Those numbers represents you're sticky bits:

777 gives permissions for all the users to read, write and execute.
440 gives read permission for all Owners and Groups, except Others.

Sample:

440

r w x

4+0+0 = 4
4+0+0 = 4
0+0+0 = 0

rwx rwx rwx
4 4 0

A more comprehensive chmod tutorial can be found on the net.
