Set HISTTIMEFORMAT in .bashrc to view date and time in command history with the desired format. All future cmd executions will log correct dates, enhancing historical tracking.
Using 'less' to view files allows scrolling, searching, and customization. Navigate with G, 1G, N for better readability. Customize using -N, -i, -S options for line numbers, case, text wrapping.
