在命令行输入的文本上启动 vim 的快捷方式

Question

我在命令行中输入了一个很长的命令 – 才发现 Bash 不喜欢嵌入的单引号。这是一个简单的 tty，我从文件中为运行保存此命令的唯一方法是打开 vim 并再次开始输入这个很长的命令...

在命令行输入的文本上没有启动 vim 的快捷方式 – 直接从命令行？

Answer 1

当然有。以下命令将编辑 $VISUAL 中的当前命令行：

C-x C-e

Answer 2

我找到了我的案例的答案here:

首先关闭来自@marlar的警告（我为自己设置了一个保护自己的功能由此，见下文）：

Be very careful with this feature. If you cancel the edit, the original command line will be immediately executed. So if you are editing rm -rf <forward slash> and invoke the editor and realize you are into something dangerous and thus cancel the edit, your root file system will be deleted without further questions asked.

来自 OP @Kartik：

bash 手册页说：

edit-and-execute-command (C-xC-e) Invoke an editor on the current command line, and execute the result as shell commands. Bash attempts to invoke $VISUAL, $EDITOR, and emacs as the editor, in that order.

来自@Mark E. Haase

If you use Bash's vi mode, the short cut is Esc, V...

我实际上也发现只做 v 就足以用 bash 启动 vim 命令坐在那里。

来自@karlicoss：

if your editor is vim, you can use :cq, it makes it exit with non-zero code, and prevents the command from execution

因为我对rm -rf命令很偏执（我曾经删除过2Tb的大脑数据 - 切换到 linux 10 天...幸运的是系统管理员有一个备份...实际引用：“我 20 年来从未见过如此愚蠢的事情做这个工作”......但我离题了）我把以下内容放在我的 vimrc 中如果我不小心调出 vim 和条件反射退出：

function! CheckBashEdit()
    " if the file matches this highly specific reg exp, comment the line
    "(e.g. a file that looks like: /tmp/bash-fc.xxxxxx)
    if match(@%, "\/tmp\/bash-fc\.......") != -1
        " comment out the command
        silent! execute ":%normal! I# "
        write
    endif
endfunction

" if we ended up in vim by pressing <ESC-v>, put a # at the beggining of
" the line to prevent accidental execution (since bash will execute no
" matter what! Imagine rm -rf <forward slash> was there...)
autocmd BufReadPost * :call CheckBashEdit()
