Hi,

I want to create one user who has right to excute chmod command,

Any Idea?

Hi,

You want to limit the chmod command so that only root and one other user can use chmod? Out of the box chmod can be used by all users.

Or do you wan't a regular user to be able to chmod any file on the system ?

Yes, I want a regular user to able to run chmod command for a specified path.

For example : User "A" want to change the permission of User"B"\test\ Like that

we use sudo to allow the webmaster to change permissions on files in the web tree.

Allowing a user to change the permission of any file is the same as granting him full root access.

jlliagre is absolutely correct, and I spoke too quickly. What we actually do is somewhat different, exactly for the security reasons. People in the web group are able to upload files to the web tree. Depending on the tools they use, the ownership and permissions sometimes get screwed up. We have a perl script written by a senior admin that the web administrator is allowed to run. That perl script is owned by root, is not suid, requires sudo for someone else to run, and it fixes the ownership and permissions of specified files if and only if they are in the web tree. It specifically does not give the person unbridled access to chmod. That would allow someone to upload a script (or make a copy of the shell) and make it suid root, thus gaining control of the system.

So, bottom line for the OP, if you give this one user the right to unbridled use of chmod, you might as well just give them the root password.
