So far, we’ve only worked with an example where the underlying ...

  Python on the other hand is a very robust language; however some operations that could be performed in bash with a single line can take a disproportionate amount of code when written in Python using os, shutil, subprocess, etc. pshell gets the best of both worlds by providing a unified, robust, and compact Python API to perform all the tasks
