I'm curious. How do you for example parse command line arguments in your shell scripts? Do you regard sed, grep and awk as dependencies when bash scripting?

I'm curious. How do you for example parse command line arguments in your shell scripts? Do you regard sed, grep and awk as dependencies when bash scripting? With regards Python. The subprocess, os, sys etc modules are standard library modules. There is no dependency overhead in using them. Most smaller Python scripts manage very nicely with the standard library.
