Re: tasksel
Hi All
thanks for the help on this, I am slowly getting somewhere with this.
For now, and with the help, I am going to get the option menu working,
so this allows a single option to be selected from the menu and run,
then goes back to the menu for the user to choose the next option if needed.
Once I am more comfortable with this, I can look at doing something with
the checkbox component of whiptail etc.
Thanks again
Regards
Paul
