macos Mac OS X 终端：将选项+删除映射到“向后删除单词”

Mac OS X Terminal: Map option+delete to "backward delete word"

提问by ibz

Tried to map it from Preferences -> Settings -> Keyboard, but the "key" combo box has only "forward delete" but no "delete". My keyboard on the other hand has only "delete" and no "forward delete"!

试图从首选项 -> 设置 -> 键盘映射它，但“键”组合框只有“向前删除”而没有“删除”。另一方面，我的键盘只有“删除”而没有“向前删除”！

Is there some other way to do it except from the preferences?

除了偏好之外，还有其他方法可以做到吗？

OS X's terminal runs bash, which includes readline support. Follow Glomek's advice and tell terminal to use option as meta key (or else use Esc) and then you've got a bunch of handy options: Ctrl+wdeletes prev word (as does Meta+delete as mentioned), but you can also use Meta+f and Meta+b to walk forward and backwards thru words, Ctrl+aand Ctrl+eto beginning and end of line, Ctrl+kdelete (kill) from cursor to end of line, and a bunch more.

OS X 的终端运行 bash，其中包括 readline 支持。遵循 Glomek 的建议并告诉终端使用 option 作为元键（或者使用Esc），然后你有一堆方便的选项：Ctrl+w删除上一个词（正如前面提到的 Meta+delete），但你也可以使用 Meta+ f 和 Meta+b 向前和向后遍历单词，Ctrl+a和Ctrl+e到行首和行尾，Ctrl+k从光标到行尾删除（杀死），等等。

Delete a word going back:

删除一个词回去：

Ctr-w.

Ctrl-W。

回答by Dustin

By default meta backspace does a backwards word yank in most shells. If you press escape and then press backspace, that pretty much works everywhere.

默认情况下，元退格键在大多数 shell 中执行向后单词 yank。如果您按 Esc 键然后按退格键，这几乎可以在任何地方使用。

?W(control+W) is not the same thing than meta + delete (ESC+delete if you don't have checked use option as meta key) meta+delete will treat / _as word delimiter where ^Wwill consider space as delimiter.

?W(control+W) 与 meta + delete 不同（ESC+delete 如果您没有选中 use 选项作为元键） meta+delete 将/ _视为单词分隔符，其中^W将空格视为分隔符。

e.g. using ESC+Bakcspace on (cursor at the end)

例如使用 ESC+Bakcspace on（最后的光标）

rm /dira/dirb/file1

gives

给

rm /dira/dirb/

while ^W on the same will give

而 ^W 同样会给

rm

So it is better to use \033\177 rather than ^W when defining the modifying the terminal profile. That way you are really mapping ?? to what esc? is doing and you keep having ^W to erase word based on space delimiter.

所以在定义修改终端配置文件时最好使用\033\177而不是^W。这样你真的在映射？？什么esc？正在做，并且您一直在使用 ^W 来根据空格分隔符擦除单词。

I would love to be able to post an image on how do this but as a newbies I can't.

我希望能够发布有关如何执行此操作的图像，但作为新手我不能。

refer to bouke comment to see how to modify terminal profile.

回答by Bouke

In your Terminal's profile, you can bind ?? (option+delete) to ?W (control+W), so it works similar to other apps.

在您的终端配置文件中，您可以绑定 ?? (option+delete) 到 ?W (control+W)，所以它的工作方式类似于其他应用程序。
