Delete terminal history in Linux
提问by Frank Vilea
When you use the up key in a Linux terminal, you can use previous commands again. Great feature. However, I started logging mysql into mysql with the sensitive details in the command.
当您在 Linux 终端中使用向上键时，您可以再次使用以前的命令。很棒的功能。但是，我开始使用命令中的敏感细节将 mysql 登录到 mysql。

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.
如果您使用 bash，则终端历史记录将保存在名为 .bash_history 的文件中。删除它，历史将消失。
However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.
但是，对于 MySQL，更好的方法是不要在命令行中输入密码。如果您只指定 -p 选项而没有值，则系统会提示您输入密码，并且不会被记录。
Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:
如果不想每次都输入密码，另一种选择是将其存储在 my.cnf 文件中。创建一个名为 ~/.my.cnf 的文件，内容如下：
[client]
user = <username>
password = <password>
Make sure to change the file permissions so that only you can read the file.
确保更改文件权限，以便只有您可以读取该文件。
Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.
当然，这样您的密码仍然保存在您的主目录中的纯文本文件中，就像之前保存在 .bash_history 中一样。
