I was curious as to why the developers of Git decided to have three
methods to get the manual for a verb. I am a developer who strives to
understand Git to its fullest extent, and will share any information
given on this question.
While reading Pro Git 2nd Ed. I came across these three methods:
$ git help <verb>
$ git <verb> --help
$ man git-<verb>
I tested all three to confirm they were equivalent.
What was the motivation behind the complication, if any? I presume
most developers would not provide multiple commands that do the same
thing for absolutely no reason, so I led myself to ask this question.
