描述
此函数遍历/etc/group文件中的条目。在列表context中返回以下内容-
($name,$passwd,$gid,$members)
$members标量包含作为组成员的登录名的空格分隔列表。仅在标量context中使用时才返回组名。在Windows下,请考虑使用Win32API::Net模块。
语法
以下是此函数的简单语法-
getgrent
返回值
此函数在定标器context和列表context(名称,密码,组ID和成员列表)中返回组名。
例
以下是显示其基本用法的示例代码-
#!/usr/bin/perl
while( ($name,$passwd,$gid,$members)=getgrent() ) {
print "Name =$name\n";
print "Password =$passwd\n";
print "GID =$gid\n";
print "Members =$members\n";
}
执行上述代码后,将产生以下输出-
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 = . . .
