Hello, I have read the requirements for your project and think that I can deliver the exact quality of work that you may need.
My primary development environment is Ubuntu Linux and I use bash scripts for automating builds and testing code every now and then.
Apart from this, I have used bash for filesystem modification (cat, standard stream redirection, sed, awk, touch, tar, rm etc.), web access( wget and curl ), automating system configuration editing( .bashrc, cron-jobs) as well as software installation(path and env variable export).
On the python side I have written code that does all this along with using several tools like system shell.
