Change Default User Home Directory While Adding A New User

By default, when we create or add users to Linux System, user’s default home directory is created to /home. To change default directory to /opt/, we need to change few settings as mentioned below:
STEP 1: Open /etc/default/useradd
# nano /etc/default/useradd
The default home directory defined by HOME variable, find line that read as follows:
HOME=/home replace to HOME=/opt/
Save and close the file. Now you can add user using regular useradd command:
# useradd uddika
# passwd -d uddika
Verify user information:
# finger uddika
Output:
Login: uddika Name: uddika Directory: /opt/uddika Shell: /bin/bash Never logged in. No mail. No Plan.
