Hello,

this code block:

#+BEGIN_SRC shell :session n42 :shebang "#!/bin/bash"
for i in "aa" "bb" "cc" ; do
echo "u: $i"
done
#+end_src

produces this output when it first runs:

#+RESULTS:
|    |    |    |    |
| >  | >  | u: | aa |
| u: | bb |    |    |
| u: | cc |    |    |


After the first run, subsequent runs produce this output:

#+RESULTS:
|    |    |    |
| >  | u: | aa |
| u: | bb |    |
| u: | cc |    |

If I set :session to none the output is always like follows:

#+RESULTS:
| u: | aa |
| u: | bb |
| u: | cc |


I think that last one is what one would expect ;). Anyways, using sessions,
is there a way to get rid off of the shell's continuation prompts?

Regards
hmw

  PS2=""
  
  in the shell script?

    does that work for you? I had to evaluate
    (add-to-list 'tramp-remote-process-environment "PS2=> "). Otherwise
    tramp/emacs would wait forever after sending the first line of the for
    loop.

      oh, I should add that. Albeit the example I posted earlier runs locally,
      my goal is to execute the shell code on a remote machine. But the
      result is the same with both scenarios.
      
      #+BEGIN_SRC shell :session n42 :dir /localhost: :shebang "#!/bin/bash"
      for i in "aa" "bb" "cc" ; do
      echo "u: $i"
      done
      #+end_src

  Hi,
  
  A similar issue - a code block and the result below would be normal.
  
  #+BEGIN_SRC shell
    echo $PWD
  #+END_SRC
  
  #+Results:
  : /Users/shin/Documents
  
  
  However, when I specified a session name, the first evaluation returns a
  table-format value as below, ...
  
  #+BEGIN_SRC shell :session *shell*
    echo $PWD
  #+END_SRC
  
  #+Results:
  |                       |
  | /Users/shin/Documents |
  
  
  ... but, the second or more latter evaluations return the normal value.
  
  #+BEGIN_SRC shell :session *shell*
    echo $PWD
  #+END_SRC
  
  #+Results:
  : /Users/shin/Documents
  
  
  ... How can I get the normal value in all evaluations of the session?
  
  I attached the session log in the *shell* buffer below. I am using Org mode
  version 9.1.6 (9.1.6-16-g86a382-elpaplus @
  /Users/shin/.emacs.d/elpa/org-plus-contrib-20180115/ on macOS.
  
  Regards,
  Shintaro
