http://stackoverflow.com – So I want to verify the exit code of a specific command runuser -s /bin/bash @user_name -c $command > /dev/null 2>&1 & How can I find whether the command runuser -s /bin/bash @user_name -c $command executed correctly? I tried using $? but it doesn't work because it is always 0 ( the result of redirection is 0) How can i find the exit code of that command ? (HowTos)
