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!

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.

Denny

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 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)

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.
