How to create script in Unix

First of all we need Unix environment to create the script.

• 1. vi MyFirstScript.sh
• 2. type echo "Hello World"
• 3. exit and save :wq!
• 4. change mode the file as a executable file => chmod 775 MyFirstScript.sh (I will tell about 775 later)
• 5. now the script can be execute, type ./MyFirstScript.sh
