Shellconf.py – Simple remote configuration with shell for UNIX/Linux systems

Post by adionditsak » Thu, Mar 20, 2014, 2:14 PM UTC

Hi all,

I have created my second Python script, and would appreciate comments, contributions or just someone to discuss it with, as i am sure it can be optimized in many ways, as it is a part of my learning. The script is for configuring UNIX/Linux machines with shell scripts with Python - So pretty much a Python way of Fucking shell scripts.

I added it to Github so you can view it there: https://github.com/adionditsak/shellconf.py :-)

Sincerely, Anders

Along this line, you might find "cogs" (a toolkit for developing command-line utilities in Python) useful to build upon, it's an internal tool we use at Prometheus that's MIT licensed: https://bitbucket.org/prometheus/cogs

Good stuff. Take a look at Fabric for another (and very commonly-used) example of Python wrapping SSH: http://docs.fabfile.org. Also you might look to Paramiko for a native SSH implementation: https://github.com/paramiko/paramiko.

The explanation:

   "Run local shell scripts chronologically on defined remote servers asynchronously."

reads like Yoda-speak to me. :)

Hehe the shell scripts are executed one by one chronologically, but the request to the servers are asynchronously. Does not work so good yet tho... need to fix it :-)

EDIT: With that said... could be awesome we contributions.

Hi Nburger,

Thanks.

Yeah, Fabric is awesome. Really like it. Have not looked that much at Paramiko tho.

While Python is likely more widely installed than Ruby, I still don't understand, why use Python to run a bunch of shell scripts? Why not use the shell to run the scripts?

    for f in scripts/*;do
      #logrotate here
      scripts/"$f" &> "logs/$f.log"
    done

or something like that?

EDIT: not trying to be rude, I just don't understand.

Makes sense. Was thinking the same... Just doing this for learning actually. I think it makes sense tho to do it in Python, Ruby or something else, if you want to steamline it in some way with structure/architecture. I would like to see the bash version tho :-)
