Follow the man page:

man sudo

you will need to add the user to the sudousers file under /etc/ by using visudo

All the answers are in the man page

example:

user types:

sudo chmod 774 /home/user/bla

or you can give the user full root permissions:

sudo /bin/bash

Instead of user rights elevation that susdo provides, you might be better off using setfacl if there is a specific location where you want the user to have these rights.


setfacl is equivalent to chmod but allows the admin to configure multiple levels of access to the same folder.
i.e.
group1 has read-only access /resourcefolder
group2 has read-write access /resourcefolder
these can only be seen using getfacl /resourcefolder

setfacl -m g:group1:rx /resourcefolder
setfacl -m g:group2:rwx /resourcefolder

for user you would use u:username:rights

ls / | grep resourcefolder
will have a + at the end of drwxr-xr-x+ to indicate that there is an ACL.

A few options.

1. Add the user to the owning group of /opt and change permission of /opt to allow it group writeable "chmod g+rwx /opt"

2. Just open /opt to be writable by the world (not recommended) "chmod ago+rwx /opt"

3. Create an acl to allow that single user access to write to /opt. "setfacl -m u:<user>:rwx /opt", replacing <user> with the proper uid.
