如何查自己的hostname ?

使用hostname 或者hostnamectl 命令

$ hostname
dai-MS-7B89
$ hostnamectl
 Static hostname: dai-MS-7B89
       Icon name: computer-desktop
         Chassis: desktop
      Machine ID: d55c62a250474c459bda9aecc21307a7
         Boot ID: e97354108f364004a0775ce12cc57d98

sudo hostnamectl set-hostname  myhost
