bash - 如何清除/删除终端中的当前行？(How do I clear/delete the current line in terminal?)

Question

If I'm using terminal and typing in a line of text for a command, is there a hotkey or any way to clear/delete that line?

(如果我正在使用终端并为命令输入一行文本，是否有热键或任何方式来清除/删除该行？)

For example, if my current line/command is something really long like:

(例如，如果我当前的行/命令非常像：)

> git log --graph --all --blah..uh oh i want to cancel and clear this line <cursor is here now>

Is there a hotkey or command to go from the above to:

(是否有热键或命令从上面到：)

>

?

(？)

Usually I will press the ↓ key, and if my current line is a brand new one on the history, that will clear it.

(通常我会按↓键，如果我的当前行是历史上的全新行，那将清除它。)

But if I'm going through my command history via the ↑ key and start editing or using those commands, ↓ will only change the prompt to the next newest command in history, so it doesn't work here unless I press ↓ multiple times.

(但是如果我通过↑键浏览我的命令历史并开始编辑或使用这些命令， ↓只会将提示更改为历史记录中的下一个最新命令，因此除非我多次按↓，否则它不起作用。)
