Sometimes doing it by hand is a lot faster than a silly GUI app. :) > for what purpose do you need this? I can't speak for Kai, but here I have ranges of UIDs that are not very manageable via GUI tools (ie 1000 -> 1999 for employees, 2000 -> 2999 for permanent contractors, 3000 -> 3999 for temporary contractors, ranges for services, CVS-only users, and so on and so forth). Sorting by UID then makes it easy to glance and find the next UID in line to feed to useradd and LDAP. -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com
