The first thing you need to do in order to become productive is to have a good terminal. Throughout the book, we will be working mostly with the command line, which means that the primary piece of software we will be using is our terminal. A great terminal that we recommend is Terminator, which can be installed from the software center.

Let's go to our launcher and click on the software center icon. After it opens, click on the search input and write terminator, as shown in the following screenshot. It will probably be first in the list of results. Click on Install.

After installing Terminator, it's a good idea to drag its icon to the Launcher. For this, you just open the dash by hitting the Windows key, write terminator and drag and drop its icon into the Launcher:

Alright, now let's click on the icon to get started. You can maximize the window to have more space to play around.

Features

Now it's time to look at some of Terminator's useful features and their keyboard shortcuts. This is what the normal Terminator interface looks like:

Let's play around with it now:

• Split screen: Ctrl + Shift + O for a horizontal split:
  
• Ctrl + Shift + E for a vertical split:
  

This is probably the coolest feature of Terminator and the one we will be using the most as it is really helpful to see multiple panes and easily switch between them. You can split the screen any number of times, in any combination you want.

Resize screen: Ctrl + Shift + Arrow or just drag and drop:

• Easily move between Windows with Ctrl + Shift + Arrow.
• Close screen using Ctrl + Shift + W or Ctrl + D.
• Create tabs with Ctrl + Shift + T. This is for when you don't have any more space to split the screen:
  
• Text zoom: Ctrl + + and Ctrl + - — useful for when you need to present or when you have a person with a bad eyesight:
  

Being able to divide the screen in order to arrange the terminal in a grid, and being able to split, switch, and resize panes with keyboard shortcuts are the biggest advantages of Terminator. One big productivity killer that a lot of people don't realize is switching between using the mouse and using the keyboard. And although most people prefer using the mouse, we suggest using the keyboard as much as possible and learning the keyboard shortcuts of your most commonly used computer programs.

Being productive ultimately means having more time to focus on the things that are really important, instead of wasting time struggling to use the computer.

Hasta la vista terminal! Welcome Terminator!

Terminator works well for all sorts of tasks, especially when working long sessions on multiple items. However, sometimes there are scenarios where you need to quickly access a terminal in order to run a command, check a status, or run a task in the foreground for a long time--all of these without opening too many tabs. Guake is excellent in such situations. It is a handy, easy-to-use terminal that you can open on any workspace on top of your existing windows, by pressing F12.

We will install it right now by using a simple command line. As shown below, open your terminal and type sudo apt install guake:

Now that Guake is installed, we will go to dash and open it. To do this, we just press F12. Once it is running, you can see the notification on the top-right side of the screen. This is what it should look like:

Just like with Terminator, we will check its preferences. First of all, go to shell and enable Open new tab in current directory:

I believe you can guess what this does. Then, go scrolling and insert a really big number, like 99,999. Also, make sure Scroll | On output is unchecked:

Again, we will change the default font to Monospace 16, set the Cursor blink mode to off, and hit Close:

We can use Guake in full screen by hitting F11 and we can also resize it by dragging the margin. If you want, you can play around with the default settings to see what suits you best.

Guake does not start automatically when Ubuntu reboots, so we will have to add it to our startup application for that. To do this, open dash again, type startup applications and click add. Just type Guake in all three fields, add, and close.

What makes it so handy is the fact that you can open it on top of your current windows at any time, quickly type a command, and reopen it again later to check the status of the command.

We believe that one of the greatest inventions of mankind is copy-paste. The ability to take a piece of text from some random place and insert it to another not-so-random place is a huge time saver! Mankind would still be ages behind if computers didn't have this feature! Just imagine having to type every little command, every URL, every block of code you read! It would be a huge waste of time! And so, being such an important feature, copy-paste deserves a tool of its own for managing all the important text you copied. These types of tools are called clipboard managers. There are a lot of options for every operating system, and one good free one for Ubuntu is called clipIt. Open the terminal and type sudo apt install clipit to install it.

A good scenario for using Guake is to run ClipIt in it. By default, ClipIt occupies a terminal window but, with the help of Guake, we just hide it away!

The tool is automatically added to the startup applications, so it will start the next time you reboot.

In order to invoke ClipIt, hit Ctrl + Alt + H or click the clipboard image in the menu bar.

The first times it starts, it warns you that it stores data in plain text, so it might not be safe to use if other users use your account. Currently, it contains only the latest clipboard element.

Let's do a quick example of its usage.

We cat the content of the .profile file. And let's say we want to copy some lines of text and run them in another terminal, which looks like this:

For example, we might want to update the PATH variable, then source the .bashrc file and update the PATH variable again. Instead of copying the content again from our file, we just hit Ctrl + Alt + H and choose what we want to paste from our clipboard history:

This is a very basic example. ClipIt mostly comes in handy when you work long hours on your computer and need to paste something that you copied from a website hours earlier. It comes with a default history size of 50 items and it will show you the last 10 items in your floating window. You can increase these limits in the settings:

With ClipIt, you can copy and paste as many times as you want without losing any data. It's like a time machine for your clipboard!
