Thank you. This works great.

Re: [O] [0] Run org-babel src block periodically

[John Kitchin]

This is kind of close to what you want I think (at least it updates
every 5 seconds for me, 5 times before it stops). You might adapt it to
do what you want.

This is the block to run periodically.
#+name: time-string
#+BEGIN_SRC sh

#+END_SRC

This function will update that block. We increment a counter and cancel the 
timer when it is exceeded.
#+BEGIN_SRC emacs-lisp
(defun update-src-block (fname src-name N)
  "Update the src-block named SRC-NAME in the file FNAME upto N times."
  (if (> *counter* N)
  (progn (cancel-timer *timer*)
 (message-box "Done with timer"))

(org-babel-goto-named-src-block src-name)
(org-babel-execute-src-block)
(incf *counter*)
#+END_SRC

#+RESULTS:
: update-src-block

We use a global var for the counter and timer.
#+BEGIN_SRC emacs-lisp
(setq *counter* 0)
(setq *timer* (run-with-timer
   nil 5
   'update-src-block
   "/Users/jkitchin/blogofile-jkitchin.github.com/_blog/blog.org"

[O] [0] Run org-babel src block periodically

[Giri Prashanth]

Hi,

I would like to run a org-src block code periodically, is there any
property for org-blocks for such repeated execution.

For example if I want to watch the tail of a file periodically every 1 min
for next 1 hour, I would like to set a property like repeat for times to
repeat and keep the org file auto updated

#+BEGIN_SRC shell :repeat 60 :repeat-every 60sec
tail -n 10 file
#+END_SRC

Thank you,
