Tell me what's happening on the command line

Question

git

I'm learning Git using this tutorial githowto.com/ru/ and got acquainted with the command line for the first time.
When using the alias:
hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short
(this is from .gitconfig)

described in lesson 11, at first everything was ok, and then the following message appeared:


After that, it is no longer possible to work on the command line. Can you tell me if this is a bug or is something not working right? There are suspicions that the quotes in the alias code are to blame.

Answer 1

Thank you, it worked :) But I would like to know what is the reason? And what is it that turns on?

Answer 2

In this case, the output is piped to less( man lessin the console for reference).
