如果我使用终端并输入一行文本命令，是否有热键或任何方法来清除/删除该行?
例如，如果我当前的行/命令非常长，比如:
> git log --graph --all --blah..uh oh i want to cancel and clear this line <cursor is here now>
是否有一个热键或命令可以从上面切换到:
>
?
通常我会按↓键，如果我的当前行是一个全新的历史记录，这将清除它。但如果我通过↑键浏览我的命令历史记录并开始编辑或使用这些命令，↓只会将提示符更改为历史记录中下一个最新的命令，所以除非我多次按↓，否则它不会在这里工作。

返回刚才擦除的内容，按Esc键，然后按p:)

如果需要删除整行，且不考虑光标所在位置，可以使用kill-whole-line命令，但缺省情况下该命令是去绑定的。例如，可以通过插入将其绑定到Ctrl+Alt+K
"\e\C-k": kill-whole-line
进入Readline初始化文件(通常是~/.inputrc)。
各种各样的备注:
To avoid accidentally re-assigning a key sequence that is already in use for something else, you can check all your bindings with bind -P. Check for the suggested binding with bind -P | grep '\\e\\C-k' The Readline init file name is is taken from the shell variable INPUTRC. If it is unset, the default is ~/.inputrc, or (if that doesn't exist) /etc/inputrc. Notice that if you have ~/.inputrc, /etc/inputrc will be ignored. To reload your Readline init file, you can use Ctrl+X Ctrl+R. Links to relevant manual sections: Readline Init File Readline killing and yanking commands The bind builtin
按Ctrl+A，按Ctrl+K擦除终端中的当前行。如果需要，可以按Ctrl+Y收回。
Ctrl+A, Ctrl+K的替代方案是Ctrl+E, Ctrl+U。
