Unix: Changing UIDs and GIDs

Changing user identification numbers (UIDs) and group identification numbers (GIDs) in the IBM® AIX® operating system (AIX) isn't one of the more exciting tasks a UNIX® administrator can face. But although it's often seen as a dreadful task, it can be an essential job that an administrator must perform to keep systems in sync within the environment.

Then, you can learn how to make the changes correctly and even automate the process with UNIX scripts.
