For the UNIX side of things, we’ll try to feature one command a week that is commonly used in system\/user administration on a UNIX box. If anyone wants to contribute more, then we may do one command every two days or ‘Unix Command for the day’. Something like that.<\/p>\n
For today, it’s all about getent<\/strong>.<\/em><\/p>\n getent <\/em><\/strong>is short for Get Ent<\/strong>ries. The command suppose to get entries from an administrative database<\/em>. This database<\/em> can be passwd, group, hosts, ipnodes, services, protocols, ethers, network or netmasks.<\/p>\n For each of these\u00a0 databases, getent uses the appropriate library routines described in getpwnam, getgrnam, gethostbyaddr, gethostbyname,\u00a0\u00a0 getipnodebyaddr, getipnodebyname, getservbyname,\u00a0 getprotobyname, ethers(3SOCKET), and getnetbyname(3SOCKET), respectively.<\/p>\n getent prints out the database entries that match each of the supplied keys, one per line, int the format of the matching administrive file: Examples, passwd, group, hosts, etc….<\/p>\n Example: To check if a user dpusp or information about the TIT group:<\/p>\n # getent There.<\/p>\n","protected":false},"excerpt":{"rendered":" For the UNIX side of things, we’ll try to feature one command a week that is commonly used in system\/user administration on a UNIX box.
