bash_functions

Bash function called `sys` that displays a system dashboard in the terminal. It collects and color-codes CPU usage, memory usage, disk usage, load average, uptime, and next backup time, then prints them with icons and a storage breakdown. The function uses thresholds to color metrics green, yellow, or red based on usage levels.
