You might remember when you first started working with Linux Permissions, thinking what are all these cryptic symbols next to files and folders in the terminal. Maybe you feel this way now if you’re just starting out with Linux. Let’s face it, when we see something like drwxr-xr-x 2 root root 4096 Feb 18 18:23 Code at the command line, it’s not exactly user friendly. Maybe you know that some of these symbols have to do with permissions, and if so you are right.…
It’s helpful to learn a few Linux Keyboard Tricks. You may have noticed that when working with Linux at the command line, everything seems like a shortcut. In other words, instead of having descriptive commands such as list files, or change directory, we have things like ls and cd. What’s up with that? You might call it laziness, but really, its more of trying to get the most amount of work done with the fewest keystrokes.…
There are a few different Command Types In Linux. In fact, there are four command types in Linux. So just what are these commands? First up, there are executable programs or compiled binaries.

Linux Redirection is a very interesting topic. When we talk about redirection, we are referring to I/O or input/output redirection. It is possible to redirect the input and output of various commands to and from files, or to other commands in a process known as piping. By learning all of the standard and common commands in Linux, you’ll be able to start chaining them together to create powerful new commands or pipelines.…
The Linux files introduction episodes so far have been excellent for a gentle primer on how to get up and running with Linux using Ubuntu. Now we can get to some even more interesting challenges. In fact, that is how this Linux Series is designed to work. We start with the absolute basics, and move on to more challenging tasks. In this episode, we’ll be looking at copying, moving, creating, deleting, and overall just fully manipulating the files and directories on our Linux system.…
Let’s take a closer look at Linux Files and Directories. Our Linux system has a whole boatload of files. In our case we’re working with homestead which is a custom built Ubuntu Linux server running as a Virtual Machine on VirtualBox. To check how many files and directories a particular directory is comprised of, we can use the tree command with the –a switch to include all files and directories.…
