command-menu.sh

#!/bin/bash

# This script reads a list of descriptions and commands from a YAML-like input file and presents the options to the user.
# Each option has a description and an associated command.
# The input file format should be as follows:
#
# - description: "Description 1"
#   command: "command1"
# - description: "Description 2"
#   command: "command2"
#
# Usage: ./command-menu.sh <commands_file>
# Replace <commands_file> with the name of your input file containing the descriptions and commands.
#
# Note: Remember to make the script executable with `chmod +x command-menu.sh`
