Disclaimer as usual: This is my current best guess as to what's going on...

• Script files end with .sh extension
• Create script files with any text editor
  You must make the text file executable.
• The first line of the script file must be:
  #!/bin/bash
• Script files contain linux commands
• Script files can contain lines to execute eg. Python programs:
  -------------------------------------------

• Create and execute a script file:
• make a file named test02.sh,
  that contains three lines:
     #!/bin/bash
     pwd
     ls
• make the file executable:
  $ sudo chmod +x test02.sh
  -or- in File Manager:
  right-click the file
  select Properties (at bottom of drop-down) > Permissions
  click "Allow executing file as program"
• execute script files with:
  $ [path-to-directory-where-file-is-located]/test02.sh
  or, if you are currently in the directory where the file is located,
        -or- if you set the PATH to include the directory where your script files are located
  execute it with:
  $ ./test02.sh
  --------------------------------------------------------------------------------

• Change directory using a script file, and make the new directory persist after the command is done:
  • Add exec bash to the end of your file:
    #!/bin/bash
    cd "/home/jay/Documents"
    exec bash
