There are some operations to be switched to another user or user group next job. How can I ask in my process to switch to the specified user do?
I found that some people say calling su, su reading terminal can not read standard input stream.

ask whether the system provides the related functions?
Thank you!

Other methods are more complex, such as the su command as ...

chmod u + s pose a security risk. . . . . sudo-u username command --- not on line yet, but remember to use visudo to add a user can use sudo. . . . Do not use vi / etc / sudoers sudoers this method to edit this file, it is said will cause what is wrong, but I have never encountered an error grindstone (formerly editor is such)

precisely because of security risks to consider why I come here to ask. Because I need to give a tool used to modify another account of a file, but only allowed to modify his own part, but not modify someone else's part. So I think in the tool handle, do not he modified files. And access to that file will be exposed would cause safety problems. Do not give others root privileges.

because the system does not provide this capability, so I have to control their own. Of course, I do not pop Editor allows users to edit a part of it, I just do they have related to the CUI relevant configuration, hidden for the user file concept.

said simply, I want to ask questions and edit the file has nothing to do slightest relationship. I want to know is how other users to run the current process. This is relevant in Windows support, linux under I think I should have it.
