The obvious call: subprocess.call(["ssh", "remoteuser@remote", "python", "remote.py", "arg 1", "arg 2", "arg 3"]) won't work because ssh will break up the "arg n" strings. You need to use "'arg n'" or put the whole python command in a string like: "python TEST/testargs.py 'arg 1' 'arg 2' 'arg 3'" -- Piet van Oostrum WWW: http://pietvanoostrum.com/ PGP key: [8DAE142BE17999C4] -- http://mail.python.org/mailman/listinfo/python-list

That won't work. You need an additional level of quoting because ssh is
also a shell so it adds another level of interpretation.
The following works:
os.system('''ssh remoteuser@remote "python remote.py 'arg 1' 'arg 2' 'arg
3'"''')

Use the `subprocess` module instead (with shell=False). You then won't
need to worry about escaping.

You haven't provided very many details, so it's possible ssh is the low-impact solution, but don't discard the possibility of using a TCP socket for this.

How about something like this:
os.system ( 'ssh remoteuser@remote python remote.py "arg 1" "arg 2" "arg 3"' )

Do not let me induce you to satisfy my curiosity, from an expectation,
that I shall gratify yours. What I may judge proper to conceal, does
not concern myself alone.

Passing arguments to & executing, a python script on a remote machine from a python script on local machine (using ssh ?)
Hi c.l.p folks
Here is my situation
1. I have two machines. Lets call them 'local' & 'remote'.
Both run ubuntu & both have python installed
2. I have a python script, local.py, running on 'local' which needs to pass
arguments ( 3/4 string arguments, containing whitespaces like spaces, etc ) to
a python script, remote.py running on 'remote' (the remote machine).
I have the following questions:
1. What's the best way to accomplish my task ?
I have researched quite a bit & pretty much everybody is using ssh.
After googling a bunch, most people are using very complex workarounds to do
this sort of thing.
I googled & found people using several libraries to accomplish ssh to remote
machine & execute a command on remote machine.
paramiko ( now forked into the ssh moduke), fabric, pushy ,etc
People who have used any of these libraries, which one would you recommend, as
the most apt (simple & easy to use, lightweight, best performance, etc) for my
situation ?
2. I would prefer a solution, which does NOT require the installation of extra
libraries on the local & remote machines.
If installing external librar
3. Has anybody been able to do this using os.system ?
I tried this
>>> import os
>>> os.system ("ssh remoteuser@remote python remote.py arg1 arg2 arg3")
This worked, but if the arguments i tried to pass, had spaces, i was not able
to 'escape' the spaces.
Any & all explanations/links/code
snippets/thoughts/ideas/suggestions/feedback/comments/ of the Python tutor
community would be greatly appreciated.
Thanks a ton
cheers
