Installing Oh My ZSH in Ubuntu Cloud Server

Installing Oh My ZSH in Ubuntu Cloud Server and Setting it as default shell is tricky. Here is how we can use Oh My ZSH in few steps. There are different types of Unix Shell or Shell – as we wrote about before. We usually use Oh My ZSH on Mac with iTerm2 and Homebrew Package Manager. Also, it is possibly important to learn about the $PATH. When OS X was Mac OS X, it was actually a BSD variant. After many things happened, it became pure UNIX and name changed to OS X. GNU Linux has some differences with Mac OS X and OS X. There is a Wheel Group in OS X or Pure UNIX variants. If the Package Manager remains unaltered, the commands actually remains quite closer.

Understanding Things for Installing Oh My ZSH in Ubuntu Cloud Server

The steps for installing Oh My ZSH in Ubuntu Cloud Server is not very difficult. The difficult part, at least for the common users is the understanding the difference between two shells.  When we login (typing the username and password) either via console – sitting in front of the machine or remotely via ssh, .bash_profile is executed to configure the shell. But, if we open xterm inside Gnome or KDE environment, then .bashrc is executed before. For evoking that .bashrc we can also run a new bash instance by typing /bin/bash in a terminal – this is why in shell scripts that /bin/bash is usually written. Due to compilation, in Mac OS X (not OS X), .bash_profile is read in any situation – this is an exceptional situation among the whole UNIX breed.  ~/.profile file is for setting environment variables or executing login scripts on OS X or Mac OS X, but oddly they are not created by default. When we open iTerm2 on OS X with Homebrew, it reads the ~/.zsrc file. In OS X, we can use the source command, but Ubuntu will not understand the source command. There are advantages of using Oh My ZSH over bash, it is extremely similar to bash but does lot of extra works like typographical correction. Oh My ZSH receives frequent updates, we get prompt on OS X. Bash probably rarely receive updates. You can expect on Oh My ZSH :
