【问题描述】：
当输入一个很长的命令时，我想先在文本编辑器（例如 vi）中编辑命令，然后在出现拼写错误的情况下执行。有没有办法直接在终端中编辑命令并运行而不是通过键入 vi 来调用 vi 然后键入命令？

【问题描述】：
如果您使用的是 bash，请尝试使用 edit-and-execute-command 命令。默认情况下，它分配给Ctrl-x Ctrl-e（输入 ctrl-x，然后 ctrl-e）。
这应该会打开您环境中指定的任何编辑器。退出时缓冲区中的任何内容都将在 shell 中执行 - 包括多行命令。
【讨论】：
-
如果 bash 编辑模式是 vi，这可能不起作用。请参阅
bind -P以检查edit-and-execute-command是否完全绑定，如果没有，可以分配它（请参阅help bind）。一篇关于 GNU Readline 和 bash 的好博文：sanctum.geek.nz/arabesque/vi-mode-in-bash -
@toraritte 在 vi 模式下，
<Esc>v做到了
你可以通过设置vi编辑模式。如果你使用的是 bash，你可以输入以下内容或者把它放在你的shell configuration files：
set -o vi
你可以像在 vi 中一样使用命令模式和插入模式。
当命令已经在线时（通过按向上箭头键调用，CTRL-R、fzf 等），在 shell 上处于正常模式时，一个有用的命令是 v，因为它将启动默认编辑器来编辑命令。

【讨论】：
您是否尝试过内置的 fc（“修复命令”）shell？1
默认情况下，它会在您的编辑器中打开最后一个命令，但您可以丢弃它并将其替换为您想要的任何内容，并在退出时执行。见help fc。
Tom Ryder 在他的博文Vi mode in Bash 中提出的想法。
(1) 在fish、zsh、bash、dash 中可用，但也可能在其他版本中可用。
【讨论】：
如果您使用zsh，则shell 命令称为edit-command-line。默认情况下它没有绑定，所以在你的配置中添加这样的东西：
bindkey "^X^E" edit-command-line
现在 Ctrl+xCtrl+e 的工作方式与 bash 相同，只是在 Return 之前不执行命令被击中。
【讨论】：
如果您使用的是 fish shell 而不是 bash，您可以在编辑器中打开当前命令：
Alt-v（使用 VISUAL 环境变量中设置的编辑器）
Alt-e（使用EDITOR环境变量中设置的编辑器）
