Getting sudo and nohup to work together

Question

Linux newbie here.

I have a perl script which takes two command line inputs. I tried to run it in the background but this is what I got:

[~user]$ nohup s         


        

Answer 1

First of all, you should switch sudo and nohup. And then:

if sudo echo Starting ...
then
    sudo nohup  &
fi

The echo Starting ... can be replaced by any command that does not do much. I only use it as dummy command for the sudo.

By this the sudo in the if-condition triggers the password-check. If it is ok then the sudo session is logged in and the second call will succeed, otherwise the if will fail and not execute the actual command.
