This question already has an answer here:

So I've been messing around with my prompt in bash, editing the primary prompt of bashrc, and I noticed that the \t parameter to display the current time as the prompt does not change unless you enter a command. Is it possible to have the time countdown, or make my prompt actually count, with one number appearing and the next replacing it say after 1 second?

Thanks.

EDIT: Well, I've managed to display a running clock in the terminal itself through a script. Can I insert this into a prompt? Can I insert commands or bash code into the prompt and have it run?

EDIT: Seems you can, but it won't run unless you actually enter a command, just like \t. Looks like my only solution is changing my terminal.

  • Not really the terminal, but the shell. Bash doesn't really do updating prompts without re-printing. Zsh can: askubuntu.com/a/360172/158442 – muru Dec 18 '16 at 17:56
