Create a shell script

• First step: Use a text editor to create a text file
  • The first line must include the shell declaration sequence: #!
    • #!/bin/bash
  • Add Comment
    • Comments start with #
• Step two: Run the script
  • Give execute permission to specify the absolute or relative path of the script on the command line
    • chmod +x *.sh
  • Run the interpreter directly and run the script as a parameter of the interpreter program
    • Cat *.sh |bash
