Prereq:

If you want to change the hostname, follow this guide.

sudo apt update -y && sudo apt install -y zsh git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

       Set terminal tab / decoration color by the server name.

       Get a random colour which matches the server name and use it for the tab colour:
       the benefit is that each server gets a distinct color which you do not need
       to configure beforehand.

Hi, this is Arun and you have reached the list of software I maintain actively.

I tend to use the cmdline heavily and most of my software is about making life easier on the terminal. However, some of the utilities have seamless GUI integration or can be used as a backend to a GUI frontend.

It's many years of work but I still enjoy it thoroughly, thanks to awesome users, collaborators and maintainers.

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.
