After reading here as far as I have learned git reflog will show a list of all heads, basically it will keep a history after every checkout you do. Right?
What I don't understand is why are there long empty spaces between the list of heads? Also between lines I see :...skipping... What is that?
See the output of my git reflog
git reflog

回答1:
The blank lines and the :...skipping... lines are printed by the pager. You see these lines only when you give the pager an instruction to scroll, and then you later use the scrollbar of your terminal to go back to see "off-screen" output in your terminal.
If you do not use the pager, e.g., using git --no-pager reflog, you will not see these lines.
