But even if you cannot (for some unfathomable reason) git has you covered. You can type “git help foo” to open git’s man page for foo. So “git help tutorial” or “git help gittutorial” will both work.

Man pages are something that UNIX really did right. When you bought a UNIX, it came with many volumes of printed reference materials covering every detail. Every command you could type, every C library function you could call, every syscall, was documented right there in the manual on your shelf.

But they went one step further and provided the source for those manuals on the computer itself (literally, they were printed from the same troff files that the man viewer displays to you), so that you could view anything in those manuals without even taking them down off of your shelf. They’re indexed for instant retrieval and fast searches, so that there’s literally no delay when you ask for help. And they’re usually really high quality too! Sometimes they delve into jargon, or fail to spell out all of the consequences of some obscure option, but it is super rare that they leave anything out. Originally they were maintained by professional documentation writers, but these days they are lovingly maintained by volunteers who spend thousands of hours keeping them up to date.

There’s a whole education’s worth of material in there, and people just don’t use them. I can only blame learned helplessness, or Windows.

I bet you don’t know about Info either.
