运行带有 su 错误的 shell 脚本

Question

I have a script that is run by root and looks like this

curl -O some stuff
mv it to user guest directory
su - guest -c sh /home/guest/script.sh

Everything works fine until the last su command. It gives me the error

sh: cannot set terminal process group (-1): inappropriate ioctl for device
sh: no job control in this shell

How can I make the user guest execute the script.sh using su ?

Answer 1

From man su :

SYNOPSIS
su [options] [-] [user [argument...]]

You changed the order of the parameters. Try this way:

su -c "/path/to/sh /home/guest/script.sh" - guest

Note the quotes " before the start and after the end of the command. Moreover, I suggest you to use absolute path also for sh .
