+How To Enable Tab Complete Heroku Commands In Oh-My-Zsh
+================================================================================
+**Heroku** Client is the (Command Line Interface) CLI tool for creating and managing Heroku apps.
+
+Requirements:
+
+- Heroku toolbelt
+- Oh-My-Zsh ([How to Install][1])
+
+Note this post is not talk about heroku, it’s just to show users how they can ease typing of commands with oh-my-zsh, so am NOT going to talk into detail on doing things. Also you should have [heroku toolbelt][2] installed to make this work. Is simple for Ubuntu and Debian derivatives,Install by running the command below:
+
+    wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
+
+Open Terminal and login into heroku with you account created [here][3]:
+
+    heroku login
+    Enter your Heroku credentials.
+    Email: enockseth@unixmen.com
+    Password (typing will be hidden): 
+    Authentication successful.
+
+That shows heroku is up and running.
+
+Open **.zshrc** in your favourite text editor
+
+    vim .zshrc
+

+
+By default git is the only plugin enabled.
+
+Add **heroku** to the plugins section as shown below:
+

+
+Restart teminal, type **heroku** press tab and you’re good to go:

+Linux Basics: How To Find Size of Directory Commands
+================================================================================
+This is the first in a series of posts in coming where I’ll be writing about some **basic commands** that that will be of good use to new users.
+
+**Note**: This is targeted at people little or no command line experience..
+
+> How can I as a new user to Linux display directory properties from the terminal?
+
+### Requirements ###
+
+The only requirement is the **du** command line tool. du comes with almost every Linux distro by default.
+
+Check if du it’s on your system by running the command below in the terminal:
+
+    man du
+
+**du** command estimates file space usage
+
+### Using du ###
+
+Running du with no flag displays names of all directories including sub-directories and sizes in bytes.
+
+    du
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/du-overview.png)
+
+Using the **-h** flag displays the sizes in human readable format, that is **K, M** and **G** representing **Kilobyte, Megabyte** and **Gigabyte** respectively.
+
+    du - h
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/du-h.png)
+
+To view a specific directory indicate that after du and flag as shown below:
+
+    du -h Mapmaker
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/du-h-mapmaker.png)
+
+Use -c to see grand **total** displayed:
+
+    du -ch
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/du-ch.png)
+
+Use **-s** flag to display only grand total / disk space used for specific directories:
+
+    du -sh Mapmaker Sandbox
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/Screenshot-07052014-093858-AM.png)
+
+See man du for more flags and there uses
+
+    man du
+
+![](http://180016988.r.cdn77.net/wp-content/uploads/2014/07/man-du.png)
+
+Knows other combinations of du? Share with myself and others here too.
