Selecting a user in a shell script

[Quattro]

Hello
I run a shell script from a java application, but I need to run the command in the script under a specific user (eg testusr), how to do this in the script knowing that the command su can not save the password of the user in the same line, but it requires a password after typing su. So I can use in this case. What I have to do to achieve this? Any help will be highly appreciated. Thank you in advance.

Hi
You can transfer the request password for user "testusr" to execute commands with "sudo" and adding in / etc / sudoers this line.
Just type the following command in the terminal as a root user.

toto ALL = (ALL) NOPASSWD: / path / to / myscript

hope this works for you. Any more help needed do post, so that we can help you to resolve your problem.

Hi

You can transfer the request password for user "testusr" to execute commands with "sudo" and adding in / etc / sudoers this line.

But I only have remote access to the machine and only under a username that does not have the right to change. My request was, is there another command for su or sudo. Any other alternative for this. Thanks in advance.

Hello
I am starting with the credentials of the root or root users (in a group, or other file sudoers). you can do

sudo su - oracle

Practice for the specific environment of a user.

testusr @ root ssh sudo / usr / sbin / someusr 
(currently forget the sudoers for this user)

Now your java application must be playable for that user. If you have any more queries, then do post back.

Hello

testusr @ root ssh sudo / usr / sbin / someusr
(currently forget the sudoers for this user)

Except that since he did not have access to the root account on his machine, he can not edit the sudoers file.

sudo su - oracle

[/code]
Besides the way, if you are root, you can do simply su - oracle without using sudo.

Hi
Without root access, the only solution is through the cooperation of other users. Either the script is installed in each of them with chown or it is installed under the account running the Java code but in a folder accessible by others and is executable by all users.
Each user will then have a folder. ssh in which he put into the file authorized_keys public key of the account running the script using Java, including

from = "IP_SERVER" ssh-ind ... ... IND_PUBLIC_KEY user_running_java@your.server.com [/email]

the script using Java will then by executing a shell command via ssh:

/ usr / bin / ssh-i / home / USER_RUNNING_JAVA / .ssh / id_ind USER_RUNNING_THE_SCRIPT@your.server.com "path_to_script / thescript.sh"

But even limiting access via ssh key to the server IP, one that can connect to the account under which the Java code will access this account via ssh to all the accounts of users who participate in the system. Hope this information will help you.
