Problem to run shell-command

Problem to run shell-command

[filebat]

Hi all

Any idea why below shell-command fails?

,----------- command
| M-! etags -a -I `find -iname *.py`
`-----------

,----------- output of the error message
| `find: No such file or directory
| *.py`: No such file or directory
`-----------

If I try "M-! find -iname *.py | etags -a -", I will get complain of "Access is denied".

-- 
Thanks,
Denny

Smile for difficulty, Denny!

try 'find . -iname "*.py"'

Thanks, gavenkoa.

Well, could you have a try on your environment?

I am suspicious that shell-command of emacs doesn't support pipe, thus the
two commands fail.

Try this shell command: ls -lt1 | sort

The output in *Shell Command Output* will be alphabetically sorted  
while ls produces a listing according to modification time.

What OS are you running on?  I primarily use OS X, and shell-command 
works fine with pipes and backticks.  The only things you can't run 
using shell-command are interactive or full-screen applications.

What OS you run?

shell-command pass typed string to command interpreter like 'sh' or 
'cmdproxy.exe'.

So you must type command that correspond to your command interpreter 
language syntax.

Under Linux all work fine out of the box.

For Windows I use Cygwin (be ware put 'cygwin/bin' before 
'windows/system32' in PATH).

Also check 'shell-file-name ' and try play with:

   (setq shell-file-name (concat exec-directory "cmdproxy.exe"))

or like

   (setq shell-file-name "bash")
   (setq shell-command-switch "-c")

   (setenv "SHELL" shell-file-name)
