Aliases

Some command in git could be very long

git log --graph --oneline --branches
It would be very nice to have command to do it
something like this
 git graph
It is possible
 git config alias.graph "log --graph --oneline --branches"
after this we can use
git graph

More Aliases

We can run even programs from 


 git config alias.sbt '!sbt'
! here means run it in shell
with working directory set repository root
