It’s super safe because it doesn’t change anything. It just give you… the status. I git status everything, every time.

There are times when a command line output is too long and it’s hard to scroll through all the lines to see the beginning of the stack trace. This usually happens when you get errors and the best way to fix errors is to read the very first few lines to understand what error message you got and where the error is coming from.
