getent(8)               System Administration Commands               getent(8)

NAME
       getent - get entries from administrative database

SYNOPSIS
       getent database [key]...

DESCRIPTION
       getent  gets  a list of entries from the administrative database speci‐
       fied by database. The information generally comes from one or  more  of
       the sources that are specified for the database in nsswitch.conf(5).


       database  is the name of the database to be examined. This value can be
       passwd, group, hosts, ipnodes, services, protocols,  ethers,  networks,
       netmasks,  project,  user_attr,  prof_attr, auth_attr, exec_attr, auto‐
       mount, netgroup, initgroups, rpc, or shadow. For each  of  these  data‐
       bases, getent uses the appropriate library routines as described below.
       Many of the databases support enumeration if no key is specified on the
       command  line. Not all databases have documented libc(3LIB) interfaces.
       Man page references are supplied for each database that  has  supported
       and documented interfaces.


       Supported databases:

       passwd        Supported interfaces are documented in getpwnam(3C).


       group         Supported interfaces are documented in getgrnam(3C).


       hosts         Supported interfaces are documented in gethostbyname(3C).
                     The DNS repository does not enumerate the hosts database.


       ipnodes       Supported   interfaces  are  documented  in  getipnodeby‐
                     name(3C). The DNS repository does not enumerate the  ipn‐
                     odes database.


       services      Supported interfaces are documented in getservbyname(3C).


       protocols     Supported   interfaces   are  documented  in  getprotoby‐
                     name(3C).


       ethers        Supported interfaces are documented in  ethers(3C).  This
                     database does not support enumeration.


       networks      Supported interfaces are documented in getnetbyname(3C).


       netmasks      There  are  no  public interfaces for this database. This
                     database does not support enumeration.


       project       Supported  interfaces  are   documented   in   getprojby‐
                     name(3PROJECT).


       user_attr     Supported interfaces are documented in getuserattr(3C).


       prof_attr     Supported interfaces are documented in getprofattr(3C).


       auth_attr     Supported interfaces are documented in getauthattr(3C).


       exec_attr     Supported interfaces are documented in getexecattr(3C).


       netgroup      Supported  interfaces  are documented in getnetgrent(3C).
                     This database does not support enumeration.


       initgroups    Supported interfaces are documented in getgrouplist(3C).


       rpc           Supported interfaces are documented in getrpcbyname(3C).


       shadow        Supported interfaces are documented in getspnam(3C).



       The getent command can also be used to  fetch  entries  from  automount
       maps, by specifying the following value for database:

         automount/map



       In  this  case,  getent  retrieves the contents of map from the sources
       listed for automount in nsswitch.conf(5). As with other databases,  one
       or more specific search keys can be passed.


       Each  key  must be in a format appropriate for searching on the respec‐
       tive database. For example, it can be a  username  or  numeric-uid  for
       passwd; hostname or IP-address for hosts; or service, service/protocol,
       port, or port/proto for services.


       getent  prints each entry from the specified database that matches each
       specified key, one per line, in the format of the matching  administra‐
       tive  file:  passwd(5), group(5), project(5), networks(5), netmasks(5),
       user_attr(5), prof_attr(5), auth_attr(5), or exec_attr(5), or an  auto‐
       mount  map  file as described in automount(8). The key for exec_attr(5)
       is a profile name. If no key is given, all entries returned by the cor‐
       responding enumeration library routine (such as getpwent()  or  gethos‐
       tent())  are  printed. Enumeration is not supported on ipnodes, ethers,
       netgroup, or netmasks.


       For netgroup, either specify the netgroup name or specify the  netgroup
       name plus the triples (hostname, username, and domainname) specified as
       keys. The getent command displays each triple that matches the netgroup
       name  or  each  triple  that  matches  the  specified netgroup name and
       triple. The asterisk (*) can be used as a  wildcard  in  triples.  Note
       that you might need to escape asterisks.

   Key Interpretation for passwd, group, and user_attr Databases
       When  getent  is invoked with database set to passwd, each key value is
       processed as follows:

           o      If the key value consists only of numeric characters, getent
                  assumes that the key value is a numeric user ID and searches
                  the user database for a matching user ID.


           o      If the user ID is not found in the user database or  if  the
                  key  value  contains  any non-numeric characters, getent as‐
                  sumes the key value is a user name  and  searches  the  user
                  database for a matching user name.



       Similarly,  when getent is invoked with database set to group, each key
       value is processed as follows:

           o      If the key value consists only of numeric characters, getent
                  assumes that the  key  value  is  a  numeric  group  ID  and
                  searches the group database for a matching group ID.


           o      If the group ID is not found in the group database or if the
                  key  value  contains  any non-numeric characters, getent as‐
                  sumes the key value is a group name and searches  the  group
                  database for a matching group name.



       When  getent  is invoked with database set to user_attr, each key value
       is processed as follows:

           o      If the key value consists only of numeric characters, getent
                  assumes that the key value is a numeric user ID and searches
                  the user database for a matching user ID.


           o      If the key value contains any non-numeric characters, getent
                  assumes the key value is a user name and searches  the  user
                  database for a matching user name.


EXAMPLES
       Example 1 Listing the Contents of a Database



       The  following example lists the entire contents of the protocols data‐
       base.


         $ getent protocols


       Example 2 Listing the Contents of an Automount Map



       The following example lists the entire contents of the auto_master  au‐
       tomount map.


         $ getent automount/auto_master


       Example  3 Displaying the Entries for a User in the auto_home Automount
       Map



       The following example displays the  entry  for  user  username  in  the
       auto_home automount map.


         $ getent automount/auto_home username


       Example 4 Displaying netgroup Triples



       The  following example output displays triples that match the specified
       netgroup name (workstations) and triple. Wildcards (*) can be specified
       in the triple.



       A match is shown as the netgroup triple equal to 1.


         $ getent netgroup workstations hostname fR
         workstations          (hostname,*,*) = 1



EXIT STATUS
       The following exit values are returned:

       0    Successful completion.


       1    Command syntax was incorrect, an invalid option was  used,  or  an
            internal error occurred.


       2    At  least  one  of  the specified entry names was not found in the
            database.


       3    There is no support for enumeration on this database.
