Perl getgrent 函数
描述
此函数迭代 /etc/group 文件中的条目。 在列表上下文中返回以下内容 −
($name, $passwd, $gid, $members)
$members 标量包含作为组成员的登录名的空格分隔列表。 仅当在标量上下文中使用时才返回组名。 在 Windows 下，考虑使用 Win32API::Net 模块。
语法
以下是此函数的简单语法 −
getgrent
返回值
此函数在标量上下文和列表上下文（名称、密码、组 ID 和成员列表）中返回组名称。
示例
以下是显示其基本用法的示例代码 −
#!/usr/bin/perl
while( ($name,$passwd,$gid,$members) = getgrent() ) {
print "Name = $name\n";
print "Password = $passwd\n";
print "GID = $gid\n";
print "Members = $members\n";
}
执行上述代码时，会产生以下结果 −
Name = root Password = x GID = 0 Members = root Name = bin Password = x GID = 1 Members = root bin daemon Name = daemon Password = x GID = 2 Members = root bin daemon Name = sys Password = x GID = 3 Members = root bin adm Name = adm Password = x GID = 4 Members = root adm daemon Name = tty Password = x GID = 5 Members = . . . Name = fuse Password = x GID = 496 Members = Name = kvm Password = x GID = 36 Members = qemu Name = qemu Password = x GID = 107 Members = Name = com Password = x GID = 501 Members = Name = webgrp Password = x GID = 502 Members = com Name = railo Password = x GID = 495 Members =
