I've found a way to count the staged files. However, I'd like to get a count of the exact opposite, i.e. to learn how many files that are in the red.
When I execute git status, I see I deleted a bunch of file. However, I'd like to know how many that is. Then, I will go git reset in the same branch and check the number of tracked files (now in green, up to date). That way, I can learn how many junky files I had in my repo that wasn't tracked.
Surprisingly, googling how to count unstaged files gave no hits, so I wonder if I'm perhaps missing something very trivial at this ungodly early hour.
