Sudo Class

What's difference betwen sudo-class and pseudo-class? Like: a:hover a:link a:active a:visited

When we use sudo(pseudo) classed outside css?

Though the words are phonetically the same, they have different definitions.

pseudo-class is used in CSS as a keyword that designates a special state of the element to be selected ( :hover :visited, etc )

sudo is a command used in UNIX-like operating systems (GNU/Linux, Apple OSX, BSD, etc.) that allows a user to run a program with alternative security privileges ( normally the superuser )

Rhys Yorke -

> POSIX operating systems (Linux, Mac OS, etc.)

A better term here would be Unix-like, as Linux is not POSIX compliant also BSD isn't either, the OS on which much of OS X is based. OS X became an official licensed UNIX as of version 10.5, so it's been POSIX compliant since that time.

James Barnett, I don't think it's necessary to get in to specifics at this point. I was illustrating the idea that it was not Windows

Even Jim Hoskins states in his Console Foundations course when pointing out the similarities between Linux, BSD, Darwin:

"In fact, there is a standard that these operating systems share with each other called POSIX, or portable operating system interface."

Thank you very much...
