Exactly what each line does below is left as an exercise to the reader 😉 but to summarize— these aliases speed up common tasks, keep embedded timestamps in your history, offer shortcuts to longer-but-often-useful command sequences, highlight your command prompt, and enable colorful output for frequently used commands like grep, help monitor CPU and GPU temperature, and more.
Hint: none of these aliases/functions/commands are malicious!
