Please help me in configuring appium from the terminal. Please provide the complete steps to do it along with the software versions.

This is a little guide I've created for setting up Appium on Mac, but I'm sure you can find a lot of tutorials on this just by googling it.

First, you will need to download Android Studio: https://developer.android.com/studio/

After that, set ANDROID_HOME path in your ".bash_profile" file:

Navigate to home directory (type "cd" anywhere in terminal to go to home directory), type "ls -a" to list all files, ".bash_profile" file should be listed (if it's not listed create it with "touch .bash_profile"), add following lines to ".bash_profile" file:

Path to ANDROID_HOME

export ANDROID_HOME=/Users//Library/Android/sdk

export PATH=$ANDROID_HOME/platform-tools:$PATH

export PATH=$ANDROID_HOME/tools:$PATH

after saving file type "source .bash_profile" for changes to take effect.

Homebrew

HomeBrew is a command line package manager for OS X. It is not officially recognized, but it has become a standard de facto for the distributions of tons of useful tools. Install it by running following command from Terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)". For more info about Homebrew visit: https://brew.sh/

Python 2.7

Python should be pre-installed on macOS. To check if Python is installed type "python --version" in Terminal, output should show currently installed version (e.g. "Python 2.7.10"). If Python is not installed for some reason, you can install latest version with command "brew install python"

Appium and Appium dependencies

Install Appium desktop application from here http://appium.io/ (e.g. "appium-desktop-1.2.6-mac.zip")

Install carthage which is an Appium dependency with command "brew install carthage --HEAD" (if you want to see where carthage is installed type "which carthage")

Install pip package manager with command "sudo easy_install pip"

Install Appium Python client (if you want Java, Ruby, C# client, just change it, instead of Python) with command "pip install Appium-Python-Client"

Install Node.js and NPM with command "brew install node" (to verify node and npm are installed type "node -v" and "npm -v" in terminal)

Install appium doctor with command "sudo npm install appium-doctor -g". Appium doctor will tell you if there are some missing dependencies, to use it type "appium-doctor" in terminal.

Run commands "sudo npm install -g authorize-ios" and "sudo authorize-ios"

Set JAVA_HOME path in your ".bash_profile" file:

Navigate to home directory (type "cd" anywhere in terminal to go to home directory), type "ls -a" to list all files, ".bash_profile" file should be listed, edit ".bash_profile" with the next lines:

Path to Java

export JAVA_HOME=$(/usr/libexec/java_home)

export PATH=${JAVA_HOME}/bin:$PATH

after saving file type "source .bash_profile" for changes to take effect

If everything is set up correctly, when you run appium-doctor from Terminal you will see something like this:
