NAME
getent – get entries from administrative database
SYNOPSIS
getent database [key ...]
DESCRIPTION
The getent utility retrieves and displays entries from the administrative database specified by database, using the lookup order specified in nsswitch.conf(5). The display format for a given database is as per the “traditional” file format for that database.
The database argument may be one of:
| ethers | address name |
| group | group:passwd:gid:[member[,member]...] |
| hosts | address name [alias ...] |
| netgroup | (host,user,domain) [...] |
| networks | name network [alias ...] |
| passwd | user:passwd:uid:gid:gecos:home_dir:shell |
| protocols | name protocol [alias ...] |
| rpc | name number [alias ...] |
| services | name port/protocol [alias ...] |
| shells | /path/to/shell |
| utmpx | [time] type: properties |
Database Display format
If one or more key arguments are provided, they will be looked up in database using the appropriate function. For example, “passwd” supports a numeric UID or user name; “hosts” supports an IPv4 address, IPv6 address, or host name; and “services” supports a service name, service name/protocol name, numeric port, or numeric port/protocol name.
If no key is provided and database supports enumeration, all entries for database will be retrieved using the appropriate enumeration function and printed.
EXIT STATUS
The getent utility exits 0 on success, 1 if there was an error in the command syntax, 2 if one of the specified key names was not found in database, or 3 if there is no support for enumeration on database.
EXAMPLES
Show entry for user sshd from the passwd database:
$ getent passwd sshd sshd:*:22:22:Secure Shell Daemon:/var/empty:/usr/sbin/nologin
Show entry for TCP from the protocols database:
$ getent protocols tcp tcp 6 TCP
Show entry for the localhost IPv6 address ::1 from the hosts database:
$ getent hosts ::1 ::1 localhost localhost.my.domain
