That answer is combination of already present ones plus explanation how to add file if it is not available locally.
When I run man git
on my Linux, it has a phrase too:
The Git User’s Manual[1]
It looks like a footnote and indeed near the the end of man page I see:
1. Git User’s Manual
file:///usr/share/doc/git/html/user-manual.html
However the file is absent:
$ ls /usr/share/doc/git/html/user-manual.html
ls: cannot access '/usr/share/doc/git/html/user-manual.html': No such file or directory
I was not able to find package to add it via apt-get install
(during the search I've found that Q&A). To add it I used:
git clone https://github.com/git/htmldocs.git
The file is user-manual.html
in htmldocs
folder, I copied it
sudo mkdir --parents /usr/share/doc/git/html
sudo cp htmldocs/user-manual.html /usr/share/doc/git/html
Then one open it via web browser, e.g. as suggested in another answer with:
links /usr/share/doc/git/html/user-manual.html
(after sudo apt-get install links
as mainstream Linux distros do not have it installed by default).
