& at the end of yast2

1

Hi there
Let me know why we need to add & at the end of yast2, example “yast2 sw_single &”
Also what does minus mean in su command “su -”

Hi and welcome to the Forum :slight_smile:
The ampersand (&) just allows it to fork and give the command line back to the shell your running from. For su and the minus (-) ensures the environment used is the user switching to (eg root) and not the user it’s coming from.

su
printenv |grep $USER
exit
su -
printenv |grep $USER
