hi all, please tell me why this 2 liner script is not working!!

#!/bin/bash
oldps1="$PS1"
PS1="myprompt>"

but when type this in terminal it works!!

How about ...

export PS1="myprompt>"

thanks dr.house...but its not working...the prompt is still the same!!

try also:

PS1="myprompt>"
export PS1
5

instead of just executing the script, source it.

# source scriptname

thanks ilikecows!!!!!!!
it worked..

Either u can source it or execute the script by

 . <file name>

So the script would execute in current shell and the variable would availabe there.
