Learning bash scripting

This repository contains my solution for the challenges given in the courses that I take on linkeding learning conserning linux shell bash and bash scripting.

Details on the scripts

• The first line of evry .sh file is a shebang that tells the OS the nature of the file and the program that should be used to run it (a scrpit to run with bash in our case).

  fab@ubuntu:~/bash_scripting$ ls
  bash_script.sh
  fab@ubuntu:~/bash_scripting$ cat bash_scripit.sh | head -n 1
  #!/usr/bin/env bash

• Evry single script has a comprehensive documentation, please take some time to read the comments first.

• Great now you can just run the script this way : ./script_name.sh

  fab@ubuntu:~/bash_scripting$ ls
  bash_script.sh echo_script.sh
  fab@ubuntu:~/bash_scripting$ cat echo_script.sh
  #!/usr/bin/env bash
  # This scrpit prints a message on the screen
  echo "Bash is fun and incredibly powerful!"
  fab@ubuntu:~/bash_scripting$ ./bash_script.sh
  Bash is fun and incredibly powerful!

• All scripts have been tested with shellcheck. To install and use :

  fab@ubuntu:~/bash_scripting$ sudo apt update && sudo apt upgrade
  fab@ubuntu:~/bash_scripting$ sudo apt install shellcheck
  fab@ubuntu:~/bash_scripting$ ls
  bash_script.sh
  fab@ubuntu:~/bash_scripting$ shellcheck bash_script.sh
