I created a script in which I login as a different user(superuser) during the execution of the script but the commands after this are put on hold until i logoff the other user. Is there any way that the script following the command to login(as superuser) shall continue executing in the new logged in user?

You can run the script using nohup, which will run until the script is completed regardless of user log off.

nohup /path/to/script.sh

You can also run this in the background by using: nohup /path/to/script.sh &

  • Hi,Thanks for your response. Actually The script is meant to login to an alias of the super user and perform some functions as superuser and stay there only , not to logout from the superuser shell. using nohup makes it to logout and return to the normal user shell – Prateek May 08 '14 at 11:08

Whatever commands you are executing after loging to superuser, just collect all them in on script file. And execute them with-

nohup script.sh &

nohup in combination with "&" will help you to exit superuser session immediately.

  • Have you tried "su root -c ". Here is my output. test1@AgentX:/var/log$ su root -c whoami Output:root – ShitalSavekar May 08 '14 at 13:15
  • Actually I am using dzdo command,not su or sudo.When dzdo is used with -u & -i, it allows us to login as a different user (not madatorily as a superuser), (in my case, it was a superuser). After i gave the command: dzdo -iu I got logged in as the other user but the script paused running after this because, it was a new shell/user completely & the script resumed itself as soon as i was logging off. I found a way, I can create a script in the superuser's directory & invoke that script through my local script using the command: dzdo -u Eg: dzdo -u newuser sh abc.sh – Prateek May 09 '14 at 03:55
