You can do following steps to start a new thread.
Navigate to HOME when you login here, then go to forum option above. You will see lots of different sub forums like Shell scripting, Home work etc. You can click anyone of the forum which is suitable to your thread. Then at left corner you will see a button named New Thread by clicking there you can start a new thread.

In fact it did work, you just didn't notice:

When you start a script like you did:

the following happens: the shell starts a fresh new shell process for you. Then, inside this shell process, your script is started. It prompts you and sets the PS1-variable. Then it exits - taking the newly set prompt with it. What you saw afterwards was the prompt of the first shell again. This shell was never left, it just ran a command (another shell) and resumed after this command exited.

For what you want there is the dot "." command. Run your script this way:

Code:

dgo@Linux ~ : . changeprompt.sh

This will prevent the shell from starting a new shell in which the script would be run. Instead it will run it in the shell currently running, this way modifying the variable you want (not just its copy).

I hope this helps.

Hi bakunin...

Should the sourcing of the script read . ./changeprompt.sh for the current drawer?

(If not then I stand corrected.)

Wisecracker = Yes, that def' did the trick

Probably. But since the script worked the first time without the dot it should work this time without the dot too. Otherwise the threads o/p would have gotten a "command not found" or something such, yes?
