Change user directory
Use sudo and at to schedule the usermod command, which changes the user's home dir.
sudo at "now +5 minutes" # Run the following commands in 5 minutes
In the at interface
usermod -m -d /new/home/path # Change user home dir (-d) and move (-m) the content into the new folder
Ctrl+D to exit the at interface. Logout, wait 10 minutes, and login.
