从彩虹表中为密码添加数字

Question

对于我的安全课程，我获得了这项任务：

Break into "wpa2own" (WPA2-PSK protected) on campus.

Your source can't recall the exact passphrase, but it's SSID was "wpa2own" 
and she remembered that the password started with a number 
(coincidentally your student ID [studentID]) concatenated with a password 
out of a famous, real-world password list from the Internet: [studentID][password]). 

我已经设置了运行必要软件的方法，但是如何让我的Linux框将[studentID]附加到我现有的单词列表中？我已经看过＆＃34; Crunch＆＃34;，一个密码列表创建软件，但它没有这个功能。

Answer 1

无需编写脚本，请使用sed：

sed 's/^/studentID/' passwordlist.txt > out.txt

这将添加您的学生ID＆＃39;到每行的开头
