where to find it
a new look to User Manager
Problem with graphical tools
only practical for adding a few users, but tasks need to be automated for larger number of users

4. Shell window Tasks are done manually Example: course accounts in UNIX
Used when 10 or more users are added at the same time. Scripts are used.
Example: Perl script for Linux accounts
create accounts: addaccounts
create passwords: createpass
summary script: addstudents
Example: course accounts in UNIX
home directories: homedir.do
change ownership: chown.do
change group: chgrp.do
assign permissions: chmod.do
use text editor (or worksheet program) and create entries to the password file.
Use editor and copy and paste the entries.
