  Use vim or gedit or any editor to write shell script
  
  syntax is : chmod permission your-script-name
  
  for eg:
  $ chmod +x your-scipt-name
  $ chmod 755 your-script-name [will Read-write & execute for owner(7), while for group & other permission is read & execute(5)]
  
  Executing the script:
  $ bash bar(your-script-name)
  $ sh bar(your-script-name)
  $ ./bar(your-script-name)
  
  . command-name
  for example
  $ .trollhard
  
  Now try shell scripting
  Open Gedit or Vim
  type;
  
  

  $ vi first
  #
  #My first shell script
  #
  clear
  echo "Trolls are cute"

  Save the script & run using below command using "Executing the script" commands given above.
