git lola

git config --global alias.lola "log --graph --decorate --pretty=oneline --abbrev-commit --all"

Could you please tell me the argument to show "committer's name" as well?

Something like this might do what you want. You can of course change the color, remove the date (%ad), or change the date format (--date) to match what you want. The format specifiers are documented at https://git-scm.com/docs/git-log#_pretty_formats.

git log --graph --pretty='format:%C(auto)%h %d %s %C(green)%an%C(bold blue) %ad' --all --date=relative

The %an format specifier is for the author name (%cn would be the committer name).

So, this could be a good option:

git config --global alias.lola "log --graph --decorate --pretty='format:%C(auto)%h %d %s %C(green)%an%C(bold blue) %ad' --abbrev-commit --all --date=relative"

It works very well for me.

Yep. I've since tweaked my to:

git config --global alias.lola "log --graph --pretty='format:%C(auto)%h %d %s %C(green)(%ad) %C(bold blue)<%an>' --abbrev-commit --all --date=relative"

and this one, excluding the --all

git config --global alias.lol "log --graph --pretty='format:%C(auto)%h %d %s %C(green)(%ad) %C(bold blue)<%an>' --abbrev-commit --date=relative"

git config --global alias.lola "log --graph --decorate --pretty='format:%C(auto)%h %d %s %C(green)%an%C(bold blue) %ad' --abbrev-commit --all --date=relative"

So good.
