Help creating git alias

Hi,

I need some advice about creating the git command alias:

I have this as the command:

git log --pretty=format:"%h %ad %ae %s" --date=short | sed 's/@\S*//g'

The purpose is to cut off the email domain and keep only username.

I'm trying to create this as the alias:

lg = !sh -c 'git log --pretty=format:"%h %ad %ae %s" --date=short | sed 's/@\S*//g'' -

but it complains about the \S and i'm failing to come up with the escape sequence to make it work right.

I know i can work around that by creating shell alias, but it is not what i would like to have.

Any ideas?

Thanks!
