if-then-else inside Bash Alias
I am trying to make a alias for mv so it does its normal behavioer in normal folders and is replaced by git mv inside git repositories. I tried many ways. the if statement works, only the command git mv will not run correctly.
alias mv='"$(
if [ x`git rev-parse --show-toplevel 2> /dev/null` = x ];
echo mv;
else
echo "git mv";
fi)"'
bash git alias

I would use a function for that, like so:
gitmv()
{
# If in a git repo - call git mv. otherwise- call mv
if [ x`git rev-parse --show-toplevel 2> /dev/null` = x ];
then
mv "$@"
else
git mv "$@"
fi
}
Edit:
alias mv=gitmv

Although jhscheer proposed a much better solution (IMHO), it is still possible to achieve what you were trying to do with only an alias.
Your alias did not work because of the external double quotes, which make git mv a single token, and you have no git mv executable. If you remove the external double quotes, your alias should work fine.
By the way, the inner double quotes, in echo "git mv" are useless, but harmless.
I have no git repository immediately available to test, but I just tried with the following alias:
alias foo='$(if [ x"`pwd`" = x"$HOME" ] ; then echo echo; else echo echo foo; fi)'
