Hi,

local: Windows7, and shell comman is cmdproxy.exe/cmd
GNU Emacs 27.0.50 (build 1, x86_64-w64-mingw32) of 2017-11-24

In general dired buffer, if I call dired-do-shell-command on marked file
with end "&", it will call "start /b ..." to run asyn shell command.
However, it hould not happend for tramp dired buffer if the
tramp-remote-shell is not cmd.

For example, my server is linux and tramp-remote-shell is "/bin/sh". If I
run dired-do-shell-command with end "&", it suppose to send the command
directly, but it add "start /b" actually.

I attached the tramp debug for your reference.


Tramp setting:
  (push '("plink"
           (tramp-login-program        "plink")
           (tramp-login-args           (("-l" "%u") ("-P" "%p") ("-ssh")
("%h")))
           (tramp-remote-shell         "/bin/sh")
           (tramp-remote-shell-args    ("-c"))
           (tramp-copy-program         "pscp")
           (tramp-copy-args            (("-l" "%u") ("-P" "%p") ("-scp")
("-p" "%k") ("-q") ("-r")))
           (tramp-copy-keep-date t)
           (tramp-copy-recursive t)
           (tramp-default-port         22))
        tramp-methods)

The shell-command works if I use the function as below.

(defun my-dired-open-execute ()
  (interactive)
  (let* ((file-name (dired-get-file-for-visit))
         (file-ext (file-name-extension file-name))
         (case-fold-search t))
    (if (file-exists-p file-name)
        (cond
         ((and (string-match "^r$" file-ext) (file-remote-p file-name))
          (let ((default-directory (or (and (eq major-mode 'dired-mode)
                                            (dired-current-directory))
                                       default-directory)))
            (shell-command
             (format "nohup /bin/apps64/software/R/R CMD BATCH --no-restore
--no-save --slave \"%s\" &"
                     (file-name-nondirectory file-name)))
            ))
         (t (w32-shell-execute "open" file-name nil 1))))))
