The Linux getent command

I saw the getent command on a video yesterday, which can be used to view related records in the system's database, for example:

[Email protected]:~$ getent hosts GUOLIANGC 10.10.3.1 GUOLIANGC [Email protected]:~$ getent passwd MySQL Mysql:x:1003:1003::/home/mysql:/bin/sh

[email& nbsp;protected]:~$ getent--help Usage: getent [Options ...] database [key ...] Get entries from administrative database.  -S,--service=config       the service configuration to use  -?,--help                  give the system Help list       --usage                 Give a brief usage information  -V,--version               Print Program version number the Long option is mandatory or optional for a short option that corresponds to a mandatory or optional parameter. Supported databases: ahosts ahostsv4 ahostsv6 aliases ethers group Gshadow hosts Netgroup Networks passwd protocols RPC s Ervices Shadow for the bug reporting instructions, please see: .

Where the shadow database can only be viewed by the root user.
