linux - 如何在linux命令行中读取文件？

Question

我正在做这个挑战，这是其中一个级别:

An agent on Level 05 has told us about another big hack he's working on. Apparently someone broke into a popular shopping site, stole all the usernames and passwords and was going to post them online. Luckily, we got to them first and recovered the details. Why is this important? Well, it seems one of the Yakoottees was a member of that site.

He typically uses one of these three usernames: kazuya, kaz_whizz, kazuya99. We've put the recovered data on one of our servers. We've given you access, so see if you can find him on there. If we knew the password he uses maybe we can use that later.

Tip: The flag is his password.

我想我需要阅读这个名为“182k_accounts_rip.txt”的文件。我认为该目录是“/root/site_pwned”。

也许我需要读取该文件才能获取密码？ “cat”、“less”、“more”和“tail”命令不起作用。也许我需要查看当前密码以及提到的用户名？请帮忙

要读取文件，您可以使用system函数或execve系列函数从program调用vi或vim命令

int main(int argc, char *argv[]) {

        system("vim 182k_accounts_rip.txt");
        perror("system");
        /* do the stuff here like use grep to find the pattern*/
        return 0;
}
