Answer 1

Low-level explanation: The ${xxx} syntax always requires a variable name for xxx. It does not substitute an arbitrary string. To use ##, one would have to: x=$(git symbolic-ref HEAD); echo ${x##refs/heads/};

Answer 2

Try changing

!git push -u origin ${$(git symbolic-ref HEAD)##refs/heads/}

to

!git push -u origin `git symbolic-ref HEAD | sed -e "s#^refs/heads/##"`

This uses sh backticks to execute commands and sed to do the regular expression substitution.
