| <code bash> | <code bash> |

| | ====== History ====== |
| | * ''history -a'', append the current session history to the history file |
| | * ''history -s <cmd line>'', save the specified command line to history without executing it. Alternatively, prefix a line with the comment character (#) and it will be saved to history as a comment. |
| | * ''history -d <line number/range>'', delete line or range of lines from history |
| | |
| | ====== Command Delimiter ====== |
| | Automatically run a command after every command ran in the shell that prints a line that includes the current time. It makes it easier to spot commands being ran when scrolling back in the terminal. |
| | <code bash> |
| | PROMPT_COMMAND='printf "\e[32m---------------------------$(date +%Y-%m-%dT%H:%M:%S%z)---------------------------\n\e[0m"' |
