I have some question. I’m trying to create some bash script to automatically some task. I need to do the first step of the task as normal user, and su – to be root to finish the task.
I’ve been wondering if there is a way to do that? Until now i’m only been able to start the bash as normal user, complete the first step, ask for su – password, but after it connect as root, the script stop.
Is it possible to proceed with the bash after been logged as root?
Thank you in advance.
ps : If I’m not precise, or if you need some information, feel free to ask, I’ll do my possible to correct those mistake.
Have you tried using
sudo somecommand instead of trying to switch users? Your user will need to be in the ‘wheel’ user group (depending on your system) to do that.
su changes the environment (user variables etc.) so, though I haven’t tested this, you probably can’t do it in a shell script.
Your shell script was
#Do these commands as a normal user echo "Hello World" cat ./somefile#Do these commands as root su - echo "Hello again" cat /etc/somesystemfile
try changing it to
#Do these commands as a normal user echo "Hello World" cat ./somefile#Do these commands as root sudo echo "Hello again" sudo cat /etc/somesystemfile
