What does this error mean?

Question

git

Learn Git via githowto.com/ru/aliases
stuck on aliases like

git config --global alias.hist "log --pretty=format:'%h %ad | %s%d [%an]' --graph - -date=short"

warning: alias.hist has multiple values
​​error: cannot overwrite multiple values ​​with a single value. Use a regexp, --add or --replace-all to change alias.hist.

It says that the alias hist already exists? And where? And how do I change the request so that the hist alias is set? Do I need to find a file that has alias.hist and make changes there?

Answer 1

Strange - my alias normally started and works.
Try to add

hist = log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short

directly to a file ~/.gitconfig, to a section[alias]
