Even if you want to run commands in a different computer you can do that
with "C-c C-c" thanks to the ":dir folder" header argument and tramp.

As an example, suppose I have the code block below

#+begin_src sh
  hostname
#+end_src

If I run it I get something like

#+RESULTS:
: my_computer_name

However, if if I can ssh to a server called "myserver" I can change the
code block to

#+begin_src sh :dir /myserver:~/
  hostname
#+end_src

Now if I run the code block the code is executed in myserver and I get

#+RESULTS:
: myserver_host_name

Combine this with "C-c C-v b" (org-babel-execute-buffer) and you can easily
run many different commands in different machines. It is really great.

That is a very neat feature.  However

I cannot.

markup text with leading, trailing spaces

[hymie!]

Greetings.

My next SNAFU involves mark-up text.

I'd like to be able to have a series of commands in my raw org file that I
can copy-n-paste into my shell window.  But I also like to export my org
files to HTML so that I can make ePubs and keep them in my iPad.

So while I strongly prefer the exported version of
- ~command1~
- ~command2~
- ~command3~
it's hard to copy-n-paste with the tildes in the way.

Unfortunately, this
- ~ command1 ~
- ~ command2 ~
- ~ command3 ~
does not mark up the text in my exported-to-html version.

And this
#+BEGIN_SRC
  command1
  command2
  command3
#+END_SRC
is just IMO ugly.

Is there something I can do, where I can get output similar to
- ~command1~
- ~command2~
- ~command3~
without the tildes blocking my text?

It shouldn't be. Try adding the word "shell" after BEGIN_SRC, so 
that it fontifies the code correctly (the variable 
org-src-fontify-natively should be set to t, but that has been 
default for a while). Also, add shell to the loaded babel 
languages, so that you can execute the code and get the results 
right away in org:

#+BEGIN_SRC emacs-lisp
  (org-babel-do-load-languages
  'org-babel-load-languages
       '((shell . t)))
#+END_SRC

No need for "copy-n-paste", just do C-c C-c where you have your 
commands. 

Another added benefit is that it is way easier to add the shell 
scripts inside a SRC block after you press C-c ' (C-c ' again to 
go back to your org file), since then you will have the power of 
Shell-script mode available, for example:

C-c (	 to define a function
C-c TAB	 for an if statement
C-c C-l	 for an indexed loop

Try copying this example into an org file, it should fontify it 
nicely, both in the org file and in the html exported.

#+BEGIN_SRC shell
  echo "hello"
  cd
  ls
  n=1
  while [ $n -le 10 ]; do
      echo $n
      n=$(( n + 1 ))
  done
  echo "bye"
#+END_SRC

Best,

It's not that the font is ugly.  It's that
* (in the epub) the source code appears in a box
* (in the html/epub) it's impossible to tell the difference between two
different commands and a single command that was too long and word wrapped
to fit in the box
* (in the html/epub) I can't have non-monospace comments between/attached
to/within the code without drawing four or five separate boxes around my code
* (in the org file) For whatever reason, monospace code appears as a
light-gray font, which is hard to read against a white background.  I'm
sure that can be changed, but I haven't had time to figure it out yet.

I think you are making the incorrect assumption that the machine on
which I maintain my Org files is the same machine that I wish to execute
commands on.

If my commnds were all 8 characters long or less, it would be fine.
Some of my commands look like this:

adduser username -d /data/chroot/home/username -s /usr/bin/rssh -m -k /dev/null -g rssh

useradd -U -G wheel -p '$6$wcMRrkcdGeNHLT5c$0s4qezb00ISmGZSsILOyV/WJn3RnuZPkSEknwoSZ22HvbgkBTe4TQwCz/mpG.3zby.1Jwnmtsq1B.uCbyg5l./' username

pssh -x '-q -t -t' -I -i --hosts hosts_linux_rhel6 'sudo -S wget puppet/puppet/pub/system_patch.pl -O /usr/local/bin/system_patch.pl' < hostnamefile

While I admit that the "useradd" command is an extreme example,
this becomes horribly ambiguous:

adduser username -d /data/chroot/home/username -s 
/usr/bin/rssh -m -k /dev/null -g rssh
pssh -x '-q -t -t' -I -i --hosts hosts_linux_rhel6
'sudo -S wget puppet/puppet/pub/system_patch.pl -O
/usr/local/bin/system_patch.pl' < hostnamefile

Yes, or that you can ssh to it.

You could add a \ at the end of each line that does not end the 
command.

Unfortunately, it is still an incorrect assumption.

The only problem there is that I need to know in advance what my line length
limit is.  That's why I'm really hoping for something that I can use
standard automatic word-wrapping instead of "verbatim mode".

org-hide-emphasis-markers is the answer.  Setting this to true, the tildes
disappear.

Sorry to resurrect an old thread, but this isn't actually working.

The tildes disappear from the visual screen, but when I copy-n-paste, the
tildes are still copied. :(

Still looking for a solution that I like.

Customize org-ascii-verbatim-format and use ox-ascii export.

OMG.  That's the answer.  I can select the section, use C-c C-e t A
to export the selection into a buffer, and there's no formatting marks,
and I can copy and paste each line, and it's perfect.
