Changing username on centos linux

Let’s say I have the username of tom and my main group is also tom.

For some reason I now need my username to be jerry and in the group jerry.

sudo usermod -l jerry tom

That changed the username from tom to jerry. But jerry is still in the group tom.

sudo groupmod -n jerry tom

Okay. Now jerry is in the group jerry. But all jerry’s files are still in /home/tom.

sudo usermod -m -d /home/jerry jerry

Voila! Now tom is jerry.
