Basically my routine was: --------------------------------------------------------------- for d in /home /var /tmp; # See note below do find $d -uid ${OLD_UID} -exec chown -ch ${NEW_UID} {} \; find $d -gid ${OLD_GID} -exec chgrp -ch ${NEW_GID} {} \; done; --------------------------------------------------------------- [note: Depending on your setup, you might need /usr, /opt, /run or other paths as well. Avoid network based filesystems and do that job on those servers directly] There are also more tricks to do if you convert a computer withtout a centralized user database (for example LDAP/Kerberos) to become integrated with a centralized user database. But that's a different story. -- kind regards, David Sommerseth
