Red Hat alike useradd shell script

[Sasun]

Personly, I like the private usergroup scheme of RedHat. This is a simple script wich provides this:

#!/bin/bash
#
# rhuseradd.sh <username> [<group1> [[<group2>] ....<groupn>]]
# this script will choose /bin/bash as user's shell,
# will create primary user group with the same name,
# will create a home folder
# and will add this user to the list of additional groups:
# <group1> ....<groupn>
#
USERADD=/usr/sbin/useradd
GROUPADD=/usr/sbin/groupadd
SHELL=/bin/bash

user=${1}
group=${1}
shift
ag= #additional groups

for grp in ${@}; do
[ -z ${ag} ] && \
ag=${grp} || \
ag=${ag},${grp}
done

# create a primary group with name equal to username
${GROUPADD} ${group}
if [ ${?} -eq 0 ]; then
if [ ! -z ${ag} ]; then
${USERADD} -m -g ${group} -G ${ag} -s ${SHELL} ${user}
else
${USERADD} -m -g ${group} -s ${SHELL} ${user}
fi
fi

Cool script! Correct me if I'm wrong, but wouldn't you also want to chown the home directory to be owned by the corresponding private group? Or does it pick this up automatically?

of cource there was an error in this script. this one is better. one of these day I must learn shell

This is exactly what I was looking for. This should be implemented in the 1.4 release!

In my not so humble opinion, this somewhat common practice is a bad idea. If each user is added to the 'users' group, and all homedirs also belong to the 'users' group, then if a user isn't careful, every other user can peek into that user's homedir. A better solution is to create a group for each user, typically with the same group name as user name, and make that the user's primary group.

superadduser should do this job just fine. Simply emerge superadduser and the script will install and is ready to run....

superadduser appears to only be interactive, which is less than ideal for many situations.
