The usage of the hostname command under Linux is

The hostname command in Linux is mainly used to display and set the host name of the system. If you want to modify the host name, it is best to use this command. Let's learn together.

We run directly hostname can view the current host name, hostname you want to view the other command parameters, run the hostname -h as follows:

code is as follows:

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 "/p" "p"hostname -V| –version| -h| –help print info and exit "/p" "p"dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y"/p" "p"-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 "/p" "p" 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.

See the usage of -v? The command to modify the host name is as follows:

The code is as follows:

hostname -v new hostname

The above is the method of using the hostname command to modify the host name under Linux. Use this command to view the Linux host, and then modify the host name in the combined parameters, is not very convenient, so give it a try.
