Bash prompt can be set by setting the environment variable
PS1. We need to update this variable to get time in our prompt.
There are 4 ways to get the time in prompt. If you see manual page for
bash, you can see time can be set using:
\t the current time in 24-hour HH:MM:SS format \T the current time in 12-hour HH:MM:SS format \@ the current time in 12-hour am/pm format \A the current time in 24-hour HH:MM format
Note that the time is not the current time but the time when prompt was last updated. Prompt will be updated when previous command completed.
PS1="\t $ " # 11:13:54 $ PS1="\T $ " # 11:14:01 $ PS1="\@ $ " # 11:14 AM $ PS1="\A $ " # 11:14 $
Add whichever style you like to your
$HOME/.bashrc and every time you open a new terminal, you will see time in command prompt.
If you wish to show current directory with time in prompt, a nice prompt setting could be like
PS1="\w \A $ " PROMPT_DIRTRIM=2 # Resulting in prompt to look like # ~/.../bluetooth/nimble 11:16 $
PROMPT_DIRTRIM would set the number of parent directories you wish to see in the prompt.
