Bash is easy to use on manipulating files and directories (like change name or create links, etc) and on calling external programs. For simple functions, bash along is enough. However, bash does not support the complex functions. Python has a richer library that could provide support for complex functions (such compute the relative path between two paths).
I'm wondering for a task that can not be done with bash along whether it would be better to do in pure python or with a mix of both python and bash. What I care is mostly coding speed and a little bit maintainability (but not much). Can somebody provide some experience on when to combine python and bash and when to use pure python? -- http://mail.python.org/mailman/listinfo/python-list
