I am a recent convert to org-mode, and the ability to export the  
agenda is very useful. Currently I have a script that runs every 10  
seconds or so that calls:

emacs -batch -l ~/.emacs -eval '(org-batch-agenda "a" org-agenda-ndays  
1)' 2>/dev/null

In order to put the agenda items on my desktop. This works fine, until  
I start to edit the org file. From what I have gathered, this causes a  
lock to be placed, and org-batch-agenda has a collision with this  
lock, resulting in no output because it's trying to output the message  
about resolving the collision. Obviously this isn't very useful, so I  
was wondering why org-batch-agenda would have to modify the file, or  
possibly the easiest way to resolve this (I'm not amazing with Emacs).

Thanks,
Angus

The following may or may not work, depending on what happens in non- 
interactive emacs sessions when a lock is encountered.  Maybe this  
would work?

emacs -batch -l ~/.emacs -eval '(progn (defun ask-user-about-lock  
(&rest args) nil) (org-batch-agenda "a" org-agenda-ndays 1))' 2>/dev/ 
null


or

emacs -batch -l ~/.emacs -eval '(progn (defun file-locked-p (&rest  
args) nil) (org-batch-agenda "a" org-agenda-ndays 1))' 2>/dev/null


These are bad hacks, but should be OK sice creating an agenda should  
not modify any file buffers...

Simple enough solution, thanks. I think it's a bit weird that it is  
encountering the lock, but I suppose getting rid of the confirmation  
is the easiest step for a completely non-interactive session.

Thanks,
Angus

Not really!  A batch session could potentially modify the file, and  
Emacs
cannot know in advance that it will not.

I guess a properly constructed batch command would load file contents  
into temporary buffers without actually visiting files, but I used the  
fast trach to such a command by simply calling the already implemented  
commands...

I think so I might consider doing the even in the batch  
commands......  Not sure
though how dangerous this would be....
