Shell: Run other command with all but one parameter

I want to create a script name git-as which is basically an alias for calling git with a bunch of pre-defined parameters.

git --git-dir="$1/.git" --work-tree="$1/" <<OTHER PARAMS>>

When I want to call git in another repository, I use:

git-as "$SRC_REPO" commit -m "Changes made to $CLASS_NAME"

How do I get the "other params" bit working properly?

Keep in mind, I don't want the $1 param (containing the repository location) to be passed to git. Also, the other parameters may include double quotes such as the example shows them used.

In bash (but not all other shells), you can use a variant on array slicing to pick out some of the arguments without having shift the others first:

#!/bin/bash
git --git-dir="$1/.git" --work-tree="$1/" "${@:2}"

Here's how I would do it:

#!/bin/bash
readonly Directory="$1"
shift
git --git-dir="$Directory/.git" "$@"

First, this copies the repository location ($1) to another variable ($Directory). Then it uses shift to move all the program arguments to the left by one, so $@ just contains the arguments that were intended for Git. From there, it's just a simple matter of calling Git with the new arguments.

Shell scripts allow the use of shift n to left shift the $*/$@ args which may suit your purpose. 

# t.sh
echo ARGS $*
shift 
echo ARGS $*

bash t.sh 1 2 3 4 5 gives 

ARGS 1 2 3 4 5
ARGS 2 3 4 5
