How to create Bash Script on Mac

1. Create the bash script file.
   Sample: File myscript.sh

   #!/bin/bash     #”hash-bang" or “she-bang" indicating that this script is to be interpreted and run by the bash shell
   echo hello world     #prints “hello world”
   

2. Change the file permission to make it an executable. Open the terminal, navigate to the location of the file and type the following command:
   

   chmod 700 myscript.sh

3. Run the script. Type the following in the terminal:
