This is a great post - I thoroughly recommend learning how to use common commandline tools such as
sed, but also adopting a scripting language for more complicated stuff. I don't mean Bash, or another shell scripting language, but something like Node, Python or Ruby, as it'll give you the opportunity for a greater standard library, as well as tonnes of packages built by others.
