Unable to Run Scripts

1. It's better to start the first line, called hashbang, with:
   
   #!/usr/bin/env bash

   #!/usr/bin/env bash

   
   This will allow for atomatic detection where

   bash

   bash

   , the shell the script is written for, to be located upon execution.
2. You use paths starting like

   ./

   ./

   which means it will ONLY work when the script is started in the directory it expects to be started in.

   ./

   ./

   means current dir...
   So you need to change at least those, or make sure you change directory before executing the script or command that uses it.
3. Shellscripts are by convention named with a

   .sh

   .sh

   extension, this is not a requirement in Linux but more a convention, it might help...

you can right click on the folder and "Open in prompt"
