Re: How to pass shell command result to :post source-block?

See the code below:

#+NAME: ansi-escape-filter
#+begin_src emacs-lisp :var data=""
(with-temp-buffer
  (insert data)
  (ansi-color-apply-on-region (point-min) (point-max))
  (buffer-string))
#+end_src

#+RESULTS: ansi-escape-filter

#+begin_src sh :dir /sudo::  :results output :post  ansi-escape-filter(data=*this*)
tree /var/spool/postfix/
#+end_src

`:results output` is needed to avoid parsing the shell output as a
table.
`data=*this*` is needed to pass the output to `ansi-escape-filter`. You
can also check the example in the org info page for the :post header
argument.


Best,
Ihor
