我正在使用grep命令获取站点

grep -oP '\(\K[^)]*' log.txt

它向我展示了

accounts.google.com
store.steampowered.com
login.live.com

获取我正在使用的登录名/用户名

 grep -oP 'login\K[^&]*' log.txt
    grep -oP 'user=\K[^&]*' log.txt
    grep -oP 'username=\K[^&]*' log.txt
    grep -oP 'EMAIL=\K[^&]*' log.txt

它会显示我的用户名，登录名，电子邮件

Email=adressemail@gmail.com
username=steamusser
etc.

我想要做的是得到一个返回票

 accounts.google.com
 Email=adressemail@gmail.com

store.steampowered.com
 username=steamusser

如何在一行中执行所有这些grep命令。我尝试过对|进行OR操作，但对我不起作用。我是bash和grep的新手你们能帮帮我吗？

只需将您的正则表达式放在一起：

kent$  grep -oP '\(\K[^)]*|(user|username|Email|login)=[^&]*' file
accounts.google.com
Email=adressmail@gmail.com
store.steampowered.com
username=steamusser
login.live.com
login=mailhotmail@hotmail.com
