Linux hostname命令修改主機名稱__Linux

Linux中使用 hostname命令修改主機名稱。

在Linux中修改主機名稱的例子。

直接運行hostname可以查看目前的主機名稱，要查看hostname的其它命令參數，運行hostname -h如下：
Usage: hostname [-v] {hostname|-F file} set hostname (from file)
domainname [-v] {nisdomain|-F file} set NIS domainname (from file)
hostname [-v] [-d|-f|-s|-a|-i|-y|-n] display formatted name
hostname [-v] display hostname
hostname -V|–version|-h|–help print info and exit
dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y
-s, –short short host name
-a, –alias alias names
-i, –ip-address addresses for the hostname
-f, –fqdn, –long long host name (FQDN)
-d, –domain DNS domain name
-y, –yp, –nis NIS/YP domainname
-F, –file read hostname or NIS domainname from given file
This command can read or set the hostname or the NIS domainname. You can
also read the DNS domain or the FQDN (fully qualified domain name).
Unless you are using bind or NIS for host lookups you can change the
FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
part of the FQDN) in the /etc/hosts file.

看到-v的用法了嗎。修改主機名稱命令：
hostname -v 新的主機名稱
