tsdev.sh update

[rocketeeer]

• Add sudo to commands that require root to execute successfully
• Add a help() function to display a useful help message
• Check for arguments, display the help message if no arguments are provided
• Use cases instead of if/elif statements (faster)
  • Organise cases by alphabetical order
  • Add a * case to catch when there is no valid input and display a help message
• Use long format (-- vs -) command options to improve readability
• Standardise on “-“ command naming convention over a mix of “-“ and “_”
  • Specifically: change “build_api_cli” to “build-api-cli” as there is already a strong precedent among the "vue" commands and the "-h, --help" option
• Verified that all commands are still functioning the same
