| # The `hostname` command
 | |
| 
 | |
| `hostname`  is used to display the system's DNS name, and to display or set its hostname or NIS domain name.
 | |
| ### Syntax:
 | |
| 
 | |
| ```
 | |
| hostname [-a|--alias] [-d|--domain] [-f|--fqdn|--long] [-A|--all-fqdns] [-i|--ip-address] [-I|--all-ip-addresses] [-s|--short] [-y|--yp|--nis]
 | |
| ```
 | |
| 
 | |
| ### Examples:
 | |
| 
 | |
| 1. ``` hostname -a, hostname --alias ```
 | |
|     Display the alias name of the host (if used). This option is deprecated and should not be used anymore.
 | |
| 
 | |
| 2. ```hostname -s, hostname --short```
 | |
|     Display the short host name. This is the host name cut at the first dot.
 | |
| 
 | |
| 3.  ```hostname -V, hostname --version```
 | |
|     Print version information on standard output and exit successfully.
