    For example, say you had just created a folder using:. Another common problem is mistyping the command you want to run. Say you wanted to run nano , but accidentally typed nanp :. This will find the first instance of nanp in the last run command and replace it with nano. While all these shortcuts are fine and dandy, but it's worth mentioning that the history command is your friend.

    If you want to see all the recent commands you ran that included nano , for example, you could just run:. Lastly, if you want to keep certain commands out of your history, just put a space before them—i. When you're working with variations of a file—like backups or different file types—it can get tedious typing out the same commands with small tweaks. Say you want to rename just part of a filename. This runs the command with the same arguments, only with the parts inside the brace changed—the first part corresponding to the first argument, the second part corresponding to the second argument.

    The most common example of this is when you're backing up a file that you're making changes to. For example, if you are tweaking your rc. So, to do so, you can just run:. Putting nothing before the comma will just append -old to the filename after copying it with cp.

    If your new file doesn't work out and you want to restore the backed up file to its original location, you can just use:. Moving the comma to the other end of the brace will remove -old from the end of the file and restore it to its original name. The braces can also work when moving or creating multiple files at once.

    For example, if you wanted to create three numbered directories, you could just run:. While these are all pretty handy, the most useful thing you can probably do is make up your own shortcuts. After all, we all have a few commands we run over and over again, but they aren't necessarily the same for everyone. We've talked about doing this a few times before , but it really is one of the best things you can do to speed up Terminal work.

    To create a custom shortcut called an alias or function , you'll want to add a new line to your. Now, whenever you type la , the Terminal will run ls with the -a modifier, which includes hidden files. Some of thsee are built into popular Linux distributions already, but there are a ton of other useful ones. Here are some of our favorites:. This gives you a more verbose list of files than ls does on its own.

    This will make your Desktop the working directory with just a few keystrokes. You can, of course, modify this for pretty much any folder that you access regularly. This is an example of an alias that opens up a file for editing.

    If you have any files you find yourself constantly editing, this is a good one to keep around—just throw the path to your oft-used file in the quotes and edit the keyword to something that makes sense. With this, installing programs is much quicker in Ubuntu. You can just type agi chromium to install Chromium, for example. Of course, if you're using a different flavor of Linux , you can replace it with your package manager of choice. This is a neat function we've featured before that will essentially run cd and ls at the same time.

    These are just a few examples of the keyboard shortcuts, shorthand, and custom aliases that can make your life easier. There are really a ton out there, and depending on what you're using the Terminal for so often, different ones will prove useful to you. Of course, since you can make your own using alias and function , the only limits are your imagination though if you aren't that imaginative, we post some good ones around here from time to time.

    Got any of your own favorites that you'd like to share with us? To run one of the commands, continue typing it and press Tab again — for example, we could type a g, press Tab, and apt-get would appear.

    Introduction

    Tab completion is especially useful when typing file names, directories, and paths. Tab completion can even be used to automatically complete options for some commands. Bash also supports other types of completion.

    However, it does support tab completion for folder and file names. For example, we can open a Command Prompt, type cd D , and press Tab.

    This also helps when trying to run a command on a specific file name. Tab completion also works in PowerShell. It can be used to automatically fill in the name of a cmdlet, a parameter, or a file path. Tap the tab key while typing a command, file path, or option — the shell will automatically fill in the rest or show you the available options you can type. Any other operating system that uses the Bash shell will work the same. Tab completion features should also work similarly on many other shells on Unix-like systems. This is especially useful for long, complex file names, but it helps with many different things.
