Hostname Change Summary

What was done

OLD:  xiaoxin-XiaoXin-14-IAH8
NEW:  xx14

Two files were modified:

/etc/hostname — via hostnamectl set-hostname xx14
/etc/hosts — replaced old hostname with xx14 so local resolution still works

What this affects

Your terminal prompt: now shows xiaoxin@xx14 instead of xiaoxin@xiaoxin-XiaoXin-14-IAH8
hostname command returns xx14
Any network services that advertise the hostname (SSH, mDNS/Bonjour, Samba) will now use xx14
SSH known_hosts entries pointing to the old name may need updating if you connect to this machine from other devices

What does NOT change

Your username (still xiaoxin)
Your home directory (/home/xiaoxin)
WiFi/network connectivity
Hardware identification (MAC, serial, etc.)

Good to know

The change is permanent — survives reboots
If you ever need to revert: sudo hostnamectl set-hostname xiaoxin-XiaoXin-14-IAH8
Open a new terminal tab/shell to see the updated prompt (current sessions keep the old one)
