This will be a quick one… Do you use Linux over the command-line? Do you access remotely these machines using SSH? Are you sitting in front of a Windows computer? If your answers were yes to all three, I’m going to assume that you know the Putty software, and you already use it.. Now lets learn how to use it… the smart way!

Everybody that uses Linux, one way or another, will be using the command line for admin. Sure you can have those graphical tools to do the job, but there is nothing like the command line for this.

They are like your normal keys, but one keys does it all! Continue reading →

Now that we know how to change object’s permissions, let’s take a look at how to change object’s ownerships. Like we have already learned, objects can have two types of ownerships: user ownership, and group ownership. We shall learn how to change both individually, and at the same time. Looks boring? Keep reading so I can change your opinion! (or not…)
