问题描述

我在 Windows 上运行 GNU Emacs 所以输入:

I am running GNU Emacs on Windows so entering:

M-x shell

启动 Windows 命令行 DOS shell.但是，我希望能够从 Emacs 中运行 Cygwin Bash Shell(或任何其他非 Windows Shell).这怎么能轻松完成?

launches the Windows command-line DOS shell. However, I would like to instead be able to run the Cygwin Bash Shell (or any other non-Windows shell) from within Emacs. How can this be easily done?

推荐答案

shell-file-name 是控制 Emacs 在运行 shell 命令时使用哪个 shell 的变量.

shell-file-name is the variable that controls which shell Emacs uses when it wants to run a shell command.

explicit-shell-file-name 是控制启动哪个 shell M-x shell 的变量.

explicit-shell-file-name is the variable that controls which shell M-x shell starts up.

肯的回答变化您可能需要也可能不需要.

Ken's answer changes both of those, which you may or may not want.

你也可以通过临时改变explicit-shell-file-name来启动不同的shell:

You can also have a function that starts a different shell by temporarily changing explicit-shell-file-name:

(defun cygwin-shell ()
  "Run cygwin bash in shell mode."
  (interactive)
  (let ((explicit-shell-file-name "C:/cygwin/bin/bash"))
    (call-interactively 'shell)))

您可能还想将 --login 参数传递给 bash，因为您正在启动一个新的 Cygwin 会话.您可以通过设置 explicit-bash-args 来做到这一点.(注意 Mx shell 使用 explicit-PROGRAM-args，其中 PROGRAM 是 shell 路径名的文件名部分.这就是为什么你不应该设置外壳时包括 .exe.

You will probably also want to pass the --login argument to bash, because you're starting a new Cygwin session. You can do that by setting explicit-bash-args. (Note that M-x shell uses explicit-PROGRAM-args, where PROGRAM is the filename part of the shell's pathname. This is why you should not include the .exe when setting the shell.
