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。
您可以使用Ctrl+U清除开始。
你可以使用Ctrl+W删除一个单词。
也可以使用Ctrl+C取消。
如果你想保留历史记录，你可以使用Alt+Shift+#使其成为注释。

总结一下所有的答案:
Clean up the line: You can use Ctrl+U to clear up to the beginning. Clean up the line: Ctrl+E Ctrl+U to wipe the current line in the terminal Clean up the line: Ctrl+A Ctrl+K to wipe the current line in the terminal Cancel the current command/line: Ctrl+C. Recall the deleted command: Ctrl+Y (then Alt+Y) Go to beginning of the line: Ctrl+A Go to end of the line: Ctrl+E Remove the forward words for example, if you are middle of the command: Ctrl+K Remove characters on the left, until the beginning of the word: Ctrl+W To clear your entire command prompt: Ctrl + L Toggle between the start of line and current cursor position: Ctrl + XX
Ctrl+u:移动到你的行开始到一个环形缓冲区 Ctrl+k:移动到你的行的末尾到一个环形缓冲区 Ctrl+w:移动字符和(多个)字左从你的光标到一个环形缓冲区 Ctrl+y:插入环缓冲区中的最后一项，然后使用Alt+y旋转环缓冲区。按多次以继续“上一个”进入环缓冲区。
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
我有完整的快捷方式列表:
Ctrl+a Move cursor to start of line Ctrl+e Move cursor to end of line Ctrl+b Move back one character Alt+b Move back one word Ctrl+f Move forward one character Alt+f Move forward one word Ctrl+d Delete current character Ctrl+w Cut the last word Ctrl+k Cut everything after the cursor Alt+d Cut word after the cursor Alt+w Cut word before the cursor Ctrl+y Paste the last deleted command Ctrl+_ Undo Ctrl+u Cut everything before the cursor Ctrl+xx Toggle between first and current position Ctrl+l Clear the terminal Ctrl+c Cancel the command Ctrl+r Search command in history - type the search term Ctrl+j End the search at current history entry Ctrl+g Cancel the search and restore original line Ctrl+n Next command from the History Ctrl+p previous command from the History
在列表中添加:
在Emacs模式下，按Esc，然后按R，将删除整行。
我不知道为什么，只是碰巧发现了它。也许它不用于删除行，但恰好有相同的效果。如果有人知道，请告诉我，谢谢:)
在Bash中工作，但在Fish中不工作。
