>Description:
	

I miss the getent command, which is available in a lot of other OSes.
This is NetBSD's version, which builds cleanly with only some include
changes.

>How-To-Repeat:
	
>Fix:

	

Included are the diffs from NetBSD's sources, plus a shar of the
resulting files.

X.Sh NAME
X.Nm getent
X.Nd get entries from administrative database
X.Sh SYNOPSIS
X.Nm
X.Ar database
X.Op Ar key ...
X.Sh DESCRIPTION
XThe
X.Nm
Xprogram retrieves and displays entries from the administrative
Xdatabase specified by
X.Ar database ,
Xusing the lookup order specified in
X.Xr nsswitch.conf 5 .
XThe display format for a given
X.Ar database
Xis as per the
X.Dq traditional
Xfile format for that database.
X.Pp
X.Ar database
Xmay be one of:
X.Bl -column "netgroup" -offset indent -compact
X.Sy Database Ta Sy Display format
X.It ethers Ta address name
X.It group Ta group:passwd:gid:[member[,member]...]
X.It hosts Ta address name [alias ...]
X.It networks Ta name network [alias ...]
X.It passwd Ta user:passwd:uid:gid:gecos:home_dir:shell
X.It protocols Ta name protocol [alias ...]
X.It rpc Ta name number [alias ...]
X.It services Ta name port/protocol [alias ...]
X.It shells Ta /path/to/shell
X.El
X.Pp
XIf one or more
X.Ar key
Xarguments are provided, they will be looked up in
X.Ar database
Xusing the appropriate function.
XFor example,
X.Sy passwd
Xsupports a numeric UID or user name;
X.Sy hosts
Xsupports an IPv4 address, IPv6 address, or host name;
Xand
X.Sy services
Xsupports a service name, service name/protocol name, numeric port, or
Xnumeric port/protocol name.
X.Pp
XIf no
X.Ar key
Xis provided and
X.Ar database
Xsupports enumeration, all entries for
X.Ar database
Xwill be retrieved using the appropriate enumeration function and printed.
X.Sh DIAGNOSTICS
X.Nm
Xexits 0 on success,
X1 if there was an error in the command syntax,
X2 if one of the specified key names was not found in
X.Ar database ,
Xor 3 if there is no support for enumeration on
X.Ar database .
