Execute combine multiple linux commands in one line for different user

Question

Is it possible to combine multiple linux commands for different users? I mean, I'm logged on root . From root user I would like to log in on jaworows user and execute some command on jaworows .

&& seems not working, because it is executing only first command.

 root@jaworows:~# su jaworows && echo "hi"
 jaworows@jaworows:/root$ 

I would like to see "hi" when I log in on jaworows.

Answer 1

su jaworows starts a new shell; the command does not complete until you exit that shell. At that point, if the shell exists with status 0, the echo "hi" will execute.
