Flags are your Friends
CLI Flags I mean. Including the right flag can save you an hour of tedium.
This is something I learned lately, spending an hour trying to parse a CSV file created by a CLI tool. Turns out there was already a flag in the tool that could parse the file for me. It just sat there within the tool, waiting to be used. I just needed to wave the help flag in order to find it.
Interesting that with most CLI tools you need a flag in order to find other flags. Like using a word to unlock a dictionary of even more words.
