You need to have these two dot files in your HOME directory in order to customize your terminal

.bashrc
.bash_profile

To create these files, you need to use the 'touch' command.

touch .bashrc
touch .bash_profile

Open these files. You need to paste this code in your newly created files:

This is for .bash_profile

#FIND BASHRC AND READ EVERYTHING FROM THERE
if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi

This is for .bashrc

echo 'Welcome Karan!'

#Defining some aliases

# Easier navigation: .., ..., ...., ....., ~ and -
alias ..="cd .."
alias ...="cd ../.."
alias ....="cd ../../.."
alias .....="cd ../../../.."
alias ~="cd ~"
alias -- -="cd -"

alias python=python3
alias pip=pip3
alias bashrc="subl ~/.bashrc"
alias reload="source ~/.bashrc"

# GIT LOG ONELINE ALIAS
git() {
    if [[ $@ == "log" ]]; then
        command git log --oneline | more
    else
        command git "$@"
    fi
}

# DOCKER IMAGES and PS Command
docker() {
  if [[ $@ == "images" ]]; then
    command docker images --format "table {{.ID}}\t{{.CreatedSince}}\t{{.Repository}}"
  elif [[ $@ == "ps" ]]; then
    command docker ps -a --format="table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Status}}\t{{.RunningFor}}"
  else
    command docker "$@"
  fi
}

# ADDING PATH VARIABLES

#defining colors
green=$(tput setaf 46);
yellow=$(tput setaf 226);
orange=$(tput setaf 203);

PS1="\[${green}\]\u";       #username
PS1+="\[${yellow}\]@\h";    #host
PS1+="\[${orange}\]:\W"     #Working directory
PS1+="\[$(tput sgr0)\] \n> "
export PS1;

#Adding Path Variables
#Python path
export PATH=/Library/Frameworks/Python.framework/Versions/3.6/bin:$PATH
export PATH

After you have pasted this in your files, and saved them, you can go ahead and restart the terminal or you can just write the command

source ~/.bashrc

You are good to go!
