getent - get entries from administrative database SYNOPSIS
getent database [key...] getent gets a list of entries from the administrative database specified by database. The information generally comes from one or more of the sources that are specified for the database in /etc/nsswitch.conf. database is the name of the database to be examined. This can be passwd, group, hosts, ipnodes, services, protocols, ethers, project, net- works, or netmasks. For each of these databases, getent uses the appropriate library routines described in getpwnam(3C), getgrnam(3C), gethostbyaddr(3NSL), gethostbyname(3NSL), getipnodebyaddr(3SOCKET), getipnodebyname(3SOCKET), getservbyname(3SOCKET), getprotoby- name(3SOCKET), ethers(3SOCKET), getprojbyname(3PROJECT) and getnetbyname(3SOCKET), respectively. Each key must be in a format appropriate for searching on the respective 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 out the database entries that match each of the supplied keys, one per line, in the format of the matching administrative file: passwd(4), group(4), project(4), hosts(4), ipnodes(4), services(4), protocols(4), ethers(3SOCKET), networks(4), or netmasks(4). If no key is given, all entries returned by the corresponding enumeration library routine, for example, getpwent() or gethostent(), are printed. Enumeration is not supported on ipnodes. 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. /etc/nsswitch.conf name service switch configuration file /etc/passwd password file /etc/group group file /etc/inet/hosts IPv4 host name database /etc/inet/ipnodes IPv4 and IPv6 host name database /etc/services Internet services and aliases /etc/project project file /etc/protocols protocol name database /etc/ethers Ethernet address to hostname database or domain /etc/networks network name database /etc/netmasks network mask database See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ ethers(3SOCKET), getgrnam(3C), gethostbyaddr(3NSL), gethostbyname(3NSL), gethostent(3NSL), getipnodebyaddr(3SOCKET), getipnodeby- name(3SOCKET), getnetbyname(3SOCKET), getprojbyname(3PROJECT), getprotobyname(3SOCKET), getpwnam(3C), getservbyname(3SOCKET), group(4), hosts(4), ipnodes(4), netmasks(4), networks(4), nsswitch.conf(4), passwd(4), project(4), protocols(4), services(4), attributes(5) 1 Feb 2005 getent(1M)
