所有用户和组的列表 [英] List of all users and groups
问题描述
我试图让全部用户在Mac OS X 10.5以上版本的所有组的列表。我怎样才能做到这一点？
I'm trying to get a list of all users and all groups on Mac OS X 10.5+. How can I do this?
例如，我的机器上的所有用户的列表应该返回： _amavisd，_appowner，_appserver，_ard，_atsserver，_calendar，_carddav，_clamav，_coreaudiod，_cvmsroot，_cvs，_cyrus，_devdocs，_dovecot，_eppc，_installer，_jabber，_lda，_locationd，_lp，_mailman，_mcxalr， _mdnsresponder，_mysql，_pcastagent，_pcastserver，_postfix，_qtss，_sandbox，_screensaver，_securityagent，_serialnumberd，_softwareupdate，_spotlight，_sshd，_svn，_teamsserver，_timezone，_tokend，_trustevaluationagent，_unknown，_update_sharing，_usbmuxd，_uucp，_windowserver，_www，_xgridagent， _xgridcontroller，守护，戴夫，没有人，根（被精心手工编译）。
For example, the list of all users on my machine should return:
_amavisd, _appowner, _appserver, _ard, _atsserver, _calendar, _carddav, _clamav, _coreaudiod, _cvmsroot, _cvs, _cyrus, _devdocs, _dovecot, _eppc, _installer, _jabber, _lda, _locationd, _lp, _mailman, _mcxalr, _mdnsresponder, _mysql, _pcastagent, _pcastserver, _postfix, _qtss, _sandbox, _screensaver, _securityagent, _serialnumberd, _softwareupdate, _spotlight, _sshd, _svn, _teamsserver, _timezone, _tokend, _trustevaluationagent, _unknown, _update_sharing, _usbmuxd, _uucp, _windowserver, _www, _xgridagent, _xgridcontroller, daemon, dave, nobody, root (that was painstakingly compiled manually).
我怎样才能获得该列表（和所有群体的对应列表）编程？我打开替代（非C型）解决方案，如AppleScript的，命令等。
How can I get that list (and the corresponding list of all groups) programmatically? I'm open to alternative (non-c based) solutions, such as Applescript, commandline, etc.
更新后很长一段时间
TALlama的回答促使我去调查API打开目录，我发现这个清单可以很容易获得的编程
TALlama's answer prompted me to investigate the API to Open Directory, and I found that this list can be easily acquired programmatically:
#import <OpenDirectory/OpenDirectory.h>
ODSession *s = [ODSession defaultSession];
ODNode *root = [ODNode nodeWithSession:s name:@"/Local/Default" error:nil];
ODQuery *q = [ODQuery queryWithNode:root forRecordTypes:kODRecordTypeUsers attribute:nil matchType:0 queryValues:nil returnAttributes:nil maximumResults:0 error:nil];
NSArray *results = [q resultsAllowingPartial:NO error:nil];
for (ODRecord *r in results) {
NSLog(@"%@", [r recordName]);
}
这将记录在系统上每个用户的用户名。在 kODRecordTypeGroups 代将让你的所有组的列表。
That will log the usernames of every user on the system. Substituting in kODRecordTypeGroups will get you the list of all the groups.
的 - [ODQuery resultsAllowingPartial：错误：] 方法是一个的拦截的电话，所以你要么需要执行此$ C $在后台线程c或使用＆LT; ODQueryDelegate方式＆gt; 来汇总结果
The -[ODQuery resultsAllowingPartial:error:] method is a blocking call, so you'd either want to execute this code on a background thread, or use an <ODQueryDelegate> to aggregate the results.
推荐答案
你想要的工具，几乎可以肯定DSCL。做到这一点的捷径已经指出的：
The tool you want is almost certainly dscl. The shortest way to do it was already pointed out:
$ dscl . list /users
$ dscl . list /groups
如果您想了解每个用户的输出信息，但是，使用 ReadAll方法：
If you want to output information about each user, though, use readall:
$ dscl . readall /users
$ dscl . readall /groups
如果你需要以编程方式分析所述信息，使用-plist让您的生活更轻松：
And if you need to programatically parse said information, use -plist to make your life easier:
$ dscl -plist . readall /users
$ dscl -plist . readall /groups
