使用 sed 将单词替换为空白

Question

我有一个包含所有用户的 mysql 赠款的文件。看起来像这样：

GRANT USAGE ON *.* TO 'web_user'@'10.16.%' IDENTIFIED BY PASSWORD '*288A8C32D8C898U779EDA321A6CD6525DB2D3166';
GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON `users`.* TO 'web_user'@'10.16.%';
GRANT SELECT, INSERT, UPDATE, DELETE ON `zip`.* TO 'web_user'@'10.16.%';
GRANT USAGE ON *.* TO 'alarms'@'10.16.%' IDENTIFIED BY PASSWORD '*E8DEF50F129E0DAF1113382944F603677BA11260';
GRANT SELECT, EXECUTE ON `users`.* TO 'alarms'@'10.16.%';
...
...
...

我需要使用 sed 删除密码。我应该看起来像这样：

GRANT USAGE ON *.* TO 'web_user'@'10.16.%' IDENTIFIED BY PASSWORD
GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON `users`.* TO 'web_user'@'10.16.%';
GRANT SELECT, INSERT, UPDATE, DELETE ON `zip`.* TO 'web_user'@'10.16.%';
GRANT USAGE ON *.* TO 'alarms'@'10.16.%' IDENTIFIED BY PASSWORD
GRANT SELECT, EXECUTE ON `users`.* TO 'alarms'@'10.16.%';
...
...
...

Answer 1

sed 's/identified by password.*/identified by password/i'

Answer 2

这应该适合你：

sed 's/\(PASSWORD\).*$//' file

如果您想对此 file 进行更改，只需为您的 sed

添加 -i
