![]() Ls: The "ls" command, by itself, displays the contents of the cwd. To actually put all this path knowledge to use, you'll need the Terminal commands for displaying and changing files. How to display and move between files in Terminal When you first launch Terminal, you're starting in the current working directory of /Users/ myusername/ (also known as your User folder). You can then get to your Utilities folder by typing "./Utilities/" rather than "/Applications/Utilities". For instance, if you go to the "/Applications/" folder in Terminal, that's your current working directory ( cwd). Relative paths are defined based on where you've already navigated to, and represented by "./". So if you wanted to make a path to your Applications folder, you would write "/Applications/". An absolute path starts at the root level of your hard drive, and is displayed as "/". Paths take two forms: absolute paths and relative paths. Paths look similar in some ways to website sub-directories, and follow the structure of your folders. To do so, you build something called a path. You can use Terminal to get direct access to your files without using the Finder. When writing commands and paths in Terminal, almost everything is case sensitive: This means that you need to remember to properly capitalize "Dock" when referring to the Dock, or OS X won't understand your command. It’s nice when you make a typo and you don’t need to re-type all the thing.Unless you're executing a command that requires the display of text in Terminal, you won't have any indicator that what you've done has been successful you'll just get a new line with your user name on it once the command is finished processing. Pressing the up arrow will show the command you last typed. Using Oracle VM VirtualBoxs VBoxManage tool from the command line of the host operating system, you can control Oracle VM VirtualBox settings, create new VMs, and work on existing VMs. For example on macOS I can use option-click to position the cursor anywhere I want. Some systems also let you use the mouse to go to a specific place in the line. When typing commands you can move around with your left and right arrow to move the cursor around. It just gave me a few useful options with examples.Īnyway, I’m digressing. It’s a command you install, then you run it like this: tldr Most of the times when in need I use this site called tldr pages. Although I find man pages to contain too much information, as this is 1 of 14 screens of explanation for the ls command. I can change the current working directory to another folder using the cd command:Īnd every time I don’t know how to use a command, I type man to get the manual: I can list all the files in my home folder by typing ls and pressing enter: Except some delay, if the connection is a bit laggy. ![]() ![]() You use the shell locally but you could actually be connected to a server at the other side of Earth, which is pretty cool. You can create a VPS server on Amazon or DigitalOcean or where you want, and you can access it using SSH, the secure protocol to connect to a remote shell. The terminal is also the way you access a server. I don’t have time to spend configuring my shell prompts and colors manually and when something works out of the box, I take it. I really like it because it’s simple, straightforward, comes with great defaults, and also a web-based configuration. My favorite shell, to be honest, is Fish Shell. But the most popular ones are Bash and ZSH.īash is often the default, and until very recently it was the default macOS shell, but now it’s been changed to ZSH. We have Bash, ZSH, Fish Shell, CSH, and many more. Instead, we have lots and lots of different terminal interfaces, called shells. The acronym for the terminal is CLI (Command Line Interface). It’s essential for every professional computer user, because it unlocks you things that are impossible to do with a GUI (Graphical User Interface). The terminal is not just for programmers. Microsoft provides an app called Windows Terminal.Īnd Linux users know their terminals very well. MacOS comes with an app called Terminal, appropriately named. Today, well hidden and never used by consumers, we still have this way of using our computer. This was true when computers were big as entire rooms, but also was true when the first personal computers started becoming affordable and they would start with a BASIC command prompt. Computers were only accessed using the keyboard, typing weird and cryptic messages, called commands, in a terminal. Computers are great because using the mouse or touch devices we can do a lot of work, leaving the keyboard to typing our emails, blog posts or reports.
