How to create a home directory for an existing user in Linux

linux creates a home directory for an existing user

When creating a new user, sometimes the creation of the home directory fails or the home directory is forgotten, and you need to create the user's home directory later

The example uses the oracle user as an example

localhost:~ # mkdir /home/oracle
localhost:~ # chown oracle:oinstall -R /home/oracle
localhost:~ # usermod -d /home/oracle oracle
 
 
localhost:~ # grep oracle /etc/passwd
oracle:x:1000:1000::/home/oracle:/bin/bash
localhost:~ # su - oracle

Linux expansion/home directory
