During my web development, I usually need to run different terminal applications, like webpack, node server, etc. As Windows command prompt does not support tabs, I had to open multiple command prompts, which is very ineffective. This is not a problem for Mac / Linux users, as their consoles support programs like `tmux`.

Fortunately, now Windows 10 allows you to run a Linux subsystem inside windows. Once enabled, one can install a Linux distribution such as Ubuntu and can run Linux command line programs inside Windows (with some limitation though). With this, I can split my terminals into multiple parts as below.

## Setting up Split screen terminals in Windows

Follow the steps to get this setup in Windows 10.

1. Go to `Settings -> Update & Security -> For Developers` and enable `Developer Mode`. Click _Yes_ in the alert box.
2. Once you enable _Developer Mode_, now go to: `Control Panel -> Programs -> Turn Windows features on or off`. Search for `Windows Subsystem for Linux` and enable it. This will install necessary components in your system. You may have to restart your system.
3. After you restart, go to `Microsoft Store` and search for `Ubuntu`. Install this app.
4. Once `Ubuntu` is installed in your system, open it (just search for it in start menu). When it opens for the first time, it will download necessary files and will ask you to create a username and a password. This does not need to match your Windows password. Remember this username and password as this will be the `root` user and needed to install anything inside Ubuntu.
5. Now you are inside Ubuntu land. You can run linux command line applications such as vi, git, apt-get, etc.
6. Run `sudo apt-get install tmux`. This will install the terminal multiplexer application [tmux](https://en.wikipedia.org/wiki/Tmux).
7. Once `tmux` installed, now run `tmux`.

Now you can run any tmux command. For example, to split the terminal screen vertically, press `Ctrl + b` and `%`. And to split screen horizontally, press `Ctrl + b` and `"`.

## Bonus: Making your boring terminal to look awesome - ohmyzsh

The default bash terminal is good. But it is not that good without [ohmyzsh](http://ohmyz.sh/) - a framework to install themes and plugins in your terminal. Let's set this up.

1. Inside Ubuntu terminal, run `sudo apt-get install zsh`.
2. Once `zsh` is installed, switch to it by running `zsh`.
3. Now go to [http://ohmyz.sh/](http://ohmyz.sh/) and follow their instructions to install `ohmyzsh`.
4. Once it is installed, just close and reopen the Ubuntu. When `ohmyzsh` installed, it would have setup `zsh` as your default terminal.
5. Open zsh profile by running `vi ~/.zshrc` and update any theme you want in `ZSH_THEME` options. You can see the list of themes in here: [https://github.com/robbyrussell/oh-my-zsh/wiki/Themes](https://github.com/robbyrussell/oh-my-zsh/wiki/Themes)

My favorite `ohmyzsh` theme is **ys**. What's yours?


How to split the terminal into multiple screens in Windows 10


\*\*In this post, I'm going to explain how you can setup a Java development environment (JDK Eclipse) in Ubuntu. I'm using Ubuntu 10.10, but these steps should be applicable to majority of Ubuntu versions.

Let's start with JDK first.

## Install Sun JDK:

1.  Download the Linux version of latest JDK binary from the [Oracle website][1]. For Java 6, the file name would be: **_jdk-6u22-linux-i586.bin_**
2.  Copy the downloaded JDK file to a directory where you want to install the JDK. I use ***/home//java/*jdk-6u22-linux-i586.bin\*\***
3.  Open terminal window and navigate to the directory where you copied the downloaded file. Then type the command: **\*sudo sh jdk-6u22-linux-i586.bin** \*and press enter.
4.  If it asks for root password, give it and JDK installation will begin. The JDK will be installed on the same directory where the binary is placed.

That's it. JDK installation is done. But we still have one more step to complete. That is, setting up the _JAVA_HOME_ environment variable.

## Setting up JAVA_HOME environment variable:

1.  Go to Nautilus file browser (_Places -> Home Folder_) and open this file: **_'.bashrc'_**. By default this file is hidden. So, press *Ctrl H *which will show all hidden files and then you can see the *.bashrc *file.
2.  Add the below code snippet at the end of the *.bashrc *file:
    export JAVA_HOME=/home//java/jdk1.6.0_22
    PATH=.:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

    **Don't forget to change the path in first line according to where you installed your JDK**

    - That's it. Log off and Log in again for the changes to take effect. To test whether the installation successful, open Terminal and type *java -version *which should show you the currently installed JDK version.

    ## Install Eclipse:

    Installing Eclipse in Ubuntu is pretty simple. Just [download][2] the ZIP file from Eclipse.org and then unzip it. The installation is done. ![;-)][3]
