Actually I use newgrp occasionally. This is because NFS has a limit of 16 groups per user and if the group you want is not among the "first" 16 groups listed for your username, a newgrp (or a wash) can make it the current one. Why do we have/need so many groups? In a big company, for security reasons, every project, and occasionally a subdiscipline within a project, has a different group. For most day to day work I need only 1-2 groups, but occasionally something comes up for an older/different project and we need to revert back to the other groups to access those areas.
