linux - 如何将/etc/passwd 存储在散列或数组中？

Question

我想将 /etc/passwd 的内容存储在一个结构中，以便稍后更新每个值，但我不知道该使用哪个结构。

#!/usr/bin/perl

use warnings;
use strict;

open PASSWD, "/etc/passwd";
while(<PASSWD>) {

    chomp;
    my @f = split /:/;

    print "username $f[0]\n";
    print "password $f[1]\n";
    print "uid      $f[2]\n";
    print "gid      $f[3]\n";
    print "gecos    $f[4]\n";
    print "home     $f[5]\n";
    print "shell    $f[6]\n";
    print "--------------------------\n";

}

我假设它应该是一个哈希数组，其中用户名是键，但我不知道该怎么做。

“数组的哈希数组”是要走的路吗？
