   7 .TH GETENT 1M "Mar 14, 2014"
   8 .SH NAME
   9 getent \- get entries from administrative database
  10 .SH SYNOPSIS
  11 .LP
  12 .nf
  13 \fBgetent\fR \fIdatabase\fR [\fIkey\fR]...
  14 .fi
  15 
  16 .SH DESCRIPTION
  17 .sp
  18 .LP
  19 \fBgetent\fR gets a list of entries from the administrative database specified
  20 by \fIdatabase\fR. The information generally comes from one or more of the
  21 sources that are specified for the \fIdatabase\fR in \fB/etc/nsswitch.conf\fR.
  22 .sp
  23 .LP
  24 \fIdatabase\fR is the name of the database to be examined. This can be
  25 \fBpasswd\fR, \fBshadow\fR, \fBgroup\fR, \fBhosts\fR, \fBipnodes\fR, \fBservices\fR,
  26 \fBprotocols\fR, \fBethers\fR, \fBproject\fR, \fBnetworks\fR, or
  27 \fBnetmasks\fR. For each of these databases, \fBgetent\fR uses the appropriate
  28 library routines described in \fBgetpwnam\fR(3C), \fBgetspnam\fR(3C), \fBgetgrnam\fR(3C),
  29 \fBgethostbyaddr\fR(3NSL), \fBgethostbyname\fR(3NSL),
  30 \fBgetipnodebyaddr\fR(3SOCKET), \fBgetipnodebyname\fR(3SOCKET),
  31 \fBgetservbyname\fR(3SOCKET), \fBgetprotobyname\fR(3SOCKET),
  32 \fBethers\fR(3SOCKET), \fBgetprojbyname\fR(3PROJECT) and
  33 \fBgetnetbyname\fR(3SOCKET), respectively.
  34 .sp
  35 .LP
  36 Each \fIkey\fR must be in a format appropriate for searching on the respective
  37 database. For example, it can be a \fIusername\fR or \fInumeric-uid\fR for
  38 \fBpasswd\fR; \fIhostname\fR or \fIIP\fR \fIaddress\fR for \fBhosts\fR; or
  39 \fIservice\fR, \fIservice/protocol\fR, \fIport\fR, or \fIport/proto\fR for
  40 \fBservices\fR.
  41 .sp
  42 .LP
  43 \fBgetent\fR prints out the database entries that match each of the supplied
  44 keys, one per line, in the format of the matching administrative file:
  45 \fBpasswd\fR(4), \fBshadow\fR(4), \fBgroup\fR(4), \fBproject\fR(4), \fBhosts\fR(4),
  46 \fBservices\fR(4), \fBprotocols\fR(4), \fBethers\fR(3SOCKET),
  47 \fBnetworks\fR(4), or \fBnetmasks\fR(4). If no key is given, all entries
  48 returned by the corresponding enumeration library routine, for example,
  49 \fBgetpwent()\fR or \fBgethostent()\fR, are printed. Enumeration is not
  50 supported on \fBipnodes\fR.
  51 .SS "Key Interpretation for \fBpasswd\fR and \fBgroup\fR Databases"
  52 .sp
  53 .LP
  54 When \fBgetent\fR is invoked with database set to \fBpasswd\fR, each key value
  55 is processed as follows:
  56 .RS +4
  57 .TP
  58 .ie t \(bu
  59 .el o
  60 If the key value consists only of numeric characters, \fBgetent\fR assumes that
  61 the key value is a numeric user ID and searches the user database for a
  62 matching user ID.
  63 .RE
  64 .RS +4
  65 .TP
  66 .ie t \(bu
  67 .el o
  68 If the user ID is not found in the user database or if the key value contains
  69 any non-numeric characters, \fBgetent\fR assumes the key value is a user name
  70 and searches the user database for a matching user name.
  71 .RE
  72 .sp
  73 .LP
  74 Similarly, when \fBgetent\fR is invoked with database set to \fBgroup\fR, each
  75 key value is processed as follows:
  76 .RS +4
  77 .TP
  78 .ie t \(bu
  79 .el o
  80 If the key value consists only of numeric characters, \fBgetent\fR assumes that
  81 the key value is a numeric group ID and searches the group database for a
  82 matching group ID.
  83 .RE
  84 .RS +4
  85 .TP
  86 .ie t \(bu
  87 .el o
  88 If the group ID is not found in the \fBgroup\fR database or if the key value
  89 contains any non-numeric characters, \fBgetent\fR assumes the key value is a
  90 group name and searches the \fBgroup\fR database for a matching group name.
