In redhat linux we can add users with useradd command
# useradd username
to assign passwd we must use passwd command..
# passwd username
then specify passwd..........
information about all users will be saved in /etc/passwd file....

all passwords of the users must be saved in /etc/shadow in encrypted form...

all information about groups will saved in /etc/group file
we can add group using
# groupadd groupname
