+.Sh NAME
+.Nm getent
+.Nd get entries from administrative database
+.Sh SYNOPSIS
+.Nm
+.Ar database
+.Op Ar key ...
+.Sh DESCRIPTION
+The
+.Nm
+program retrieves and displays entries from the administrative
+database specified by
+.Ar database ,
+using the lookup order specified in
+.Xr nsswitch.conf 5 .
+The display format for a given
+.Ar database
+is as per the
+.Dq traditional
+file format for that database.
+.Pp
+.Ar database
+may be one of:
+.Bl -column "netgroup" -offset indent -compact
+.Sy Database Ta Sy Display format
+.It ethers Ta address name
+.It group Ta group:passwd:gid:[member[,member]...]
+.It hosts Ta address name [alias ...]
+.It networks Ta name network [alias ...]
+.It passwd Ta user:passwd:uid:gid:gecos:home_dir:shell
+.It protocols Ta name protocol [alias ...]
+.It rpc Ta name number [alias ...]
+.It services Ta name port/protocol [alias ...]
+.It shells Ta /path/to/shell
+.El
+.Pp
+If one or more
+.Ar key
+arguments are provided, they will be looked up in
+.Ar database
+using the appropriate function.
+For example,
+.Sy passwd
+supports a numeric UID or user name;
+.Sy hosts
+supports an IPv4 address, IPv6 address, or host name;
+and
+.Sy services
+supports a service name, service name/protocol name, numeric port, or
+numeric port/protocol name.
+.Pp
+If no
+.Ar key
+is provided and
+.Ar database
+supports enumeration, all entries for
+.Ar database
+will be retrieved using the appropriate enumeration function and printed.
+.Sh DIAGNOSTICS
+.Nm
+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
+.Ar database ,
+or 3 if there is no support for enumeration on
+.Ar database .
