Understanding Linux file permissions

jleveille writes “Understanding Linux file and directory permissions can be daunting for the new Linux user the first time they need to use them, but are easy to understand once you start using them on a regular basis, there are a couple of different ways to set permissions and the way you do it is your choice.We have the symbolic method:
$chmod o+x myfile
And the Absolute (Octal) method which is my choice:
$chmod 755 myfile

We cover both along with changing groups and owners.”
