GETENT(1)

NAME
getent - get entries from administrative database

SYNOPSIS
getent database [key ...]

DESCRIPTION
The getent program retrieves and displays entries from the administrative database specified by database. The order in which entries are looked up is defined by the specific database (for example, the lookup order for the “hosts” database is determined by resolv.conf(5)). The display format for a given database is as per the “traditional” file format for that database.

database may be one of:
Database | Display format
ethers | address name
group | group:passwd:gid:[member[,member]...]
hosts | address name [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

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 with one of the following values:

0   Success.
1   There was an error in the command syntax.
2   One of the specified key names was not found in database.
3   There is no support for enumeration on database.
