Configuring for Adding Users
This will make sure each user is set up appropriately with the correct group memberships, as well as copy the appropriate template of files from /etc/skel to each new user's home directory.
Modify the /etc/default/useradd that shadow installed:
useradd -D -b /home sed -i "/CREATE_MAIL_SPOOL/s/yes/no/" /etc/default/useradd
Add the default group that new users will become automatic members of:
groupadd -g 1000 users
Complete the EXPIRE and SHELL entries of /etc/default/useradd based on the current environment:
/usr/sbin/useradd -D -s/bin/bash
Create the /etc/skel directory:
Copy any personal settings you want to be applied upon user creation in this directory.
Create the adduser script and give it executable permissions:
cat > /usr/sbin/adduser << "EOF" #!/bin/sh useradd -m $1 passwd $1 gpasswd -a $1 users gpasswd -a $1 audio EOF chmod +x /usr/sbin/adduser
