When I try to use su in a script,  I perform a whoami, followed by a su

[root@btvm1 etc]#
[root@btvm1 etc]# cat aa
whoami
su - mqm
[root@btvm1 etc]#
[root@btvm1 etc]#
[root@btvm1 etc]# ./aa
root
mqm
Password:

Open in new window


As you can see, he thinks he is root, but when he tries to perform the su, he thinks he needs a pw

What is going on, how can I convince root of his identity

ok I know I am slow, but in this case the password it was happy with was the root password

1> So the question is why if I am calling a batch file from root do I need to enter my root password

2> and, How can I fix this ?

Thanks

Why are you running the batch file as root, and then trying to have it su to mqm.  Can you not just run it while logged in as user mqm?

If you are running it as root, but want it to execute a command as user mqm, then do it like this:

su mqm -c <command to run as mqm>


PS. I do not know why you are being prompted for a password in that script - I created the identical script on my system, and it changed users as it was supposed to.

You can do this with sudo.

Edit /etc/sudoers wit the following line -
<userid> ALL=(ALL)       NOPASSWD: ALL

Open in new window

sudo su - mqm -c command

Open in new window
