Apparently it's not possible to make a new directory with:

  (shell-command (concat "md " path))

where path is some string like

"\\a\\b\\c"

Is it possible at all to make a directory under the default-directory 
with elisp and using a variable rather than a literal string. Of course 
M-! works fine but that requires manual intervention. If this is not 
possible on the w32 port, can it be done in Emacs under Gnu/Linux?


Thanks for any help,

Ed

It works for me.  What happened on your machine, and which version of
Emacs did you use?

Of course, it is.  But I'd suggest to use Emacs primitives instead of
an external command:

  (make-directory path t)

w32 22.1 but I was having trouble with knowing when Emacs would 
translate / into \ when needed. After studying directory-file-name and 
file-directory-name and some other functions new to me, I did get it to 
work.

That one is new to me too. I'll use it but if I add parents arg I will 
have to learn how to handle the "Cancel" error. I could have found it 
with C-h a but I didn't think the function I needed would be among the 
commands. Is there a way to do apropos with C-h f ?
Anyway since I have cygwin df on this w2000 machine and I recently 
learned here about file-system-info on the "Dired hd drives list" thread 
I was trying to write a quick and dirty "Sneakernet" and backup program, 
polysave ["Save current buffer to other filesystems (i.e. flash drives, 
cd's, dvds, floppy) if they are mounted and with same relative path."]

Thanks, Eli; it (sort of) works now, for what it's worth.

Yes. In Icicles, `C-h f some-regexp S-TAB' shows you all functions whose names
match `some-regexp'. And you can change the regexp on the fly.

And whenever you use a command that expects a function or variable name as
input, you can see the complete help for selected completion candidates that
match your input, using `C-M-RET'.

Icicles also enhances the regular Emacs apropos commands in various ways.

You mean, "M-x apropos-command RET"?

  Both give me the same prompt anyway:

Apropos command (word list or regexp):

So I think it's ok to refer to the default key bindings for the sake of 
brevity. Anyway, what I wrote about "Cancel" error should refer to 
(write-file filespec confirm) since that needs error handling more often 
than make-directory (and parents).
