Java How to display current time in the prompt
Hello All,

I would like to display the current time in prompt.

I tried using following command:
Code:
export PS1="$(date +%k:%M:%S) $ "

but it gave me a fixed time in prompt whereas my objective is to get the current time everytime.

Code:
$ export PS1="$(date +%k:%M:%S) $ "
17:42:42 $
17:42:42 $ date
Tue Oct  2 17:42:54 PDT 2012
17:42:42 $

Please help.

Thank you - Manish

If your shell is bash you can use:

Code:
PS1='\D{%k:%M:%S} $ '

For ksh95/pdksh try:

Code:
PS1='$(date +%k:%M:%S) $ '

Otherwise try this: https://www.unix.com/shell-programmin...rent-time.html

Hello,

Thank you for replying but both the options are not working.

Please suggest other options to display the current time in prompt.

Hey,

Thats works for me:
Code:
export PS1=$(date +%k:%M:%S)$

What shell and OS do you use?

bash
Code:
trap 'PS1="$(date ) > "' 17

ksh
Code:
trap 'PS1="$(date ) > "' 47

I don't see a problem setting both traps in either shell. (date +...) whatever format in each system can be used.
