Bash CTRL to move cursor between words/strings
提问by Bryan Ruiz
I am use to using the CTRLkey to move faster when using the left and right arrow keys (goes to end of a word, instead of one char at a time).
我CTRL习惯于在使用左右箭头键时使用该键更快地移动（转到单词的末尾，而不是一次一个字符）。
Can I do that in bash somehow?
我可以以某种方式在 bash 中做到这一点吗？
I could probably code it, but I was wondering if there is something easier / already done.
我可能可以编码它，但我想知道是否有更简单的/已经完成的事情。

With the default readline key bindings, ALT+Bgoes back one word, ALT+Fgoes forward one word.
使用默认的 readline 键绑定，ALT+B后退一个词，ALT+F前进一个词。
The default Ubuntu setup additionally provides CTRL+arrows like you're used to. These are in /etc/inputrcand specified as follows:
默认的 Ubuntu 设置还CTRL像您习惯的那样提供+ 箭头。这些在/etc/inputrc并指定如下：
# mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[5C": forward-word
"\e[5D": backward-word
"\e\e[C": forward-word
"\e\e[D": backward-word
Not sure why we need three of them...
不知道为什么我们需要三个...

As Thomas explained, you can add the bindings to /etc/inputrc.
正如 Thomas 所解释的，您可以将绑定添加到/etc/inputrc.
Another alternative so it loads every time you log in, is putting them in ~/.bashrclike this:
每次登录时都会加载的另一种选择是将它们放入~/.bashrc：
#use ctl keys to move forward and back in words
bind '"\eOC":forward-word'
bind '"\eOD":backward-word'
I learned that you can use cat > /dev/nullto look at the characters that your keyboard is sending, e.g., CTRL + right arrow shows:
我了解到您可以使用cat > /dev/null来查看键盘发送的字符，例如 CTRL + 向右箭头显示：
^[OC
where ^[is the same as \eso that's where the code comes from in the bindcommand.
where^[与\eso that 是bind命令中代码的来源相同。
You can also look up bindings like this:
您还可以像这样查找绑定：
bind -p | grep forward-word
All of this is pretty damn awesome and I'm glad I found out some more power of bash.
所有这些都非常棒，我很高兴我发现了 bash 的更多功能。

A .inputrc in your home directory will cause ctrl+left to stop working on Ubuntu (for example).
主目录中的 .inputrc 将导致 ctrl+left 停止在 Ubuntu 上工作（例如）。
To get everything working, add the following to ~/.inputrc:
要使一切正常，请将以下内容添加到 ~/.inputrc：
# Include system-wide inputrc, which is ignored by default when
# a user has their own .inputrc file.
$include /etc/inputrc
