Setting up a complex git alias

Question

I'd like to set up a git alias which, upon git log would run

git log --pretty=format:"%C(yellow)%h  %C(red)%an, %C(green)%ar %""s" 
           --since=2.weeks –n20

I tried running

git config --global alias.log 'log --pretty=format:"%C(yellow)%h  
           %C(red)%an, %C(green)%ar %""s" --since=2.weeks –n20'

And confirmed that it is recorded in .gitconfig as

 28 [alias]
       …
 34   log = log --pretty=format:\"%C(yellow)%h  %C(red)%an,
                 %C(green)%ar %\"\"s\" --since=2.weeks –n20

This however does not format git output as expected.

What am I missing please?

Answer 1

From git documentation:

To avoid confusion and troubles with script usage, aliases that hide existing git commands are ignored.

You'll have to rename your alias.
