23.Dt GETENT 8
24.Os
25.Sh NAME
26.Nm getent
27.Nd get entries from administrative database
28.Sh SYNOPSIS
29.Nm
30.Ar database
31.Oo Ar key Oc Ns ...
32.Sh DESCRIPTION
33.Nm
34gets a list of entries from the administrative database specified by
35.Ar database .
36The information generally comes from one or more of the sources that are
37specified for the
38.Ar database
39in
40.Pa /etc/nsswitch.conf .
41.Pp
42.Ar database
43is the name of the database to be examined.
44This can be
45.Cm passwd ,
46.Cm shadow ,
47.Cm group ,
48.Cm hosts ,
49.Cm ipnodes ,
50.Cm services ,
51.Cm protocols ,
52.Cm ethers ,
53.Cm project ,
54.Cm networks ,
55.Cm netmasks ,
56.Cm auth_attr ,
57.Cm exec_attr ,
58.Cm prof_attr ,
59.Cm user_attr ,
60or
61.Cm netgroup .
62For each of these databases,
63.Nm
64uses the appropriate library routines described in
65.Xr getpwnam 3C ,
66.Xr getspnam 3C ,
67.Xr getgrnam 3C ,
68.Xr getnetgrent 3C ,
69.Xr gethostbyaddr 3NSL ,
70.Xr gethostbyname 3NSL ,
71.Xr getipnodebyaddr 3SOCKET ,
72.Xr getipnodebyname 3SOCKET ,
73.Xr getservbyname 3SOCKET ,
74.Xr getprotobyname 3SOCKET ,
75.Xr ethers 3SOCKET ,
76.Xr getprojbyname 3PROJECT ,
77.Xr getnetbyname 3SOCKET ,
78.Xr getauthattr 3SECDB ,
79.Xr getexecattr 3SECDB ,
80.Xr getprofattr 3SECDB ,
81and
82.Xr getuserattr 3SECDB
83respectively.
84.Pp
85Each
86.Ar key
87must be in a format appropriate for searching on the respective database.
88For example, it can be a username or numeric-uid for
89.Cm passwd ;
90hostname or IP address for
91.Cm hosts ;
92or service, service/protocol, port, or port/proto for
93.Cm services .
94.Pp
95.Nm
96prints out the database entries that match each of the supplied keys, one per
97line, in the format of the matching administrative file:
98.Xr passwd 5 ,
99.Xr shadow 5 ,
100.Xr group 5 ,
101.Xr project 5 ,
102.Xr hosts 5 ,
103.Xr services 5 ,
104.Xr protocols 5 ,
105.Xr ethers 5 ,
106.Xr netgroup 5 ,
107.Xr networks 5 ,
108.Xr netmasks 5 ,
109.Xr auth_attr 5 ,
110.Xr exec_attr 5 ,
111.Xr prof_attr 5 ,
112or
113.Xr user_attr 5 .
114If no key is given, all entries returned by the corresponding enumeration
115library routine, for example,
116.Xr getpwent 3C
117or
118.Xr gethostent 3NSL ,
119are printed.
120Enumeration is not supported on
121.Cm ipnodes ,
122.Cm ethers ,
123.Cm netgroup ,
124or
125.Cm netmasks .
126.Ss Key Interpretation for passwd, group, netgroup, and user_attr Databases
127When
128.Nm
129is invoked with
130.Ar database
131set to
132.Cm passwd ,
133each key value is processed as follows:
134.Bl -bullet
135.It
136If the key value consists only of numeric characters,
137.Nm
138assumes that the key value is a numeric user ID and searches the
139.Cm passwd
140database for a matching user ID.
141.It
142If the user ID is not found in the
143.Cm passwd
144database or if the key value contains any non-numeric characters,
145.Nm
146assumes the key value is a user name and searches the
147.Cm passwd
148database for a matching user name.
149.El
150.Pp
151When
152.Nm
153is invoked with
154.Ar database
155set to
156.Cm group ,
157each key value is processed as follows:
158.Bl -bullet
159.It
160If the key value consists only of numeric characters,
161.Nm
162assumes that the key value is a numeric group ID and searches the
163.Cm group
164database for a matching group ID.
165.It
166If the group ID is not found in the
167.Cm group
168database or if the key value contains any non-numeric characters,
169.Nm
170assumes the key value is a group name and searches the
171.Cm group
172database for a matching group name.
173.El
174.Pp
175When
176.Nm
177is invoked with
178.Ar database
179set to
180.Cm netgroup ,
181only a single lookup key is supported, which must be in the following format:
182.Bd -ragged -offset Ds
183.Ar netgroup Oo Ar host Ar user Ar domain Oc
184.Ed
185.Pp
186Specifying only the
187.Ar netgroup
188name will result in entries from the selected netgroup being displayed as
189string triples
190.Pq hostname, username, domain ,
191in a format compatible with
192.Xr netgroup 5 .
193.Pp
194Specifying the
195.Ar netgroup
196along with
197.Ar host ,
198.Ar user
199and
200.Ar domain
201will filter the netgroup display based on these entries.
202An asterisk
203.Pq \&*
204can be used as a wildcard for the
205.Ar host ,
206.Ar user
207or
208.Ar domain
209fields.
210.Pp
211Since the
212.Cm netgroup
213database does not support enumeration, a lookup key must always be specified.
214.Pp
215When
216.Nm
217is invoked with
218.Ar database
219set to
220.Cm user_attr ,
221each key value is processed as follows:
222.Bl -bullet
223.It
224If the key value consists only of numeric characters,
225.Nm
226assumes that the key value is a numeric user ID and searches the
227.Cm passwd
228database for a matching user name, which is then used as the key for
229.Cm user_attr .
230.It
231If the user ID is not found in the
232.Cm passwd
233database or if the key value contains any non-numeric characters,
234.Nm
235assumes the key value is a user name and searches the
236.Cm user_attr
237database for a matching entry.
