61.Sy Database Ta Sy Display format
62.It Li ethers Ta address name
63.It Li group Ta group:passwd:gid:[member[,member]...]
64.It Li hosts Ta address name [alias ...]
65.It Li netgroup Ta (host,user,domain) [...]
66.It Li networks Ta name network [alias ...]
67.It Li passwd Ta user:passwd:uid:gid:gecos:home_dir:shell
68.It Li protocols Ta name protocol [alias ...]

75If one or more
76.Ar key
77arguments are provided, they will be looked up in

79using the appropriate function.
80For example,
81.Dq Li passwd
82supports a numeric UID or user name;
83.Dq Li hosts
84supports an IPv4 address, IPv6 address, or host name;
85and
86.Dq Li services
87supports a service name, service name/protocol name, numeric port, or
88numeric port/protocol name.

93.Ar database
94supports enumeration, all entries for
95.Ar database
96will be retrieved using the appropriate enumeration function and printed.

98The
99.Nm
100utility exits 0 on success,
1011 if there was an error in the command syntax,
1022 if one of the specified key names was not found in
103.Ar database ,
104or 3 if there is no support for enumeration on
105.Ar database .
