You can use the {COMMIT_MESSAGE} deploy script variable to do some magic inside your deploy script. For example, skipping deployments can be done easily with this.

An example to skip a deployment:

if [[ {COMMIT_MESSAGE} =~ "skip-deployment" ]]; then
    echo "Skipping deployment upon commit message request."
    exit 0
fi

You can even step it up a notch, flush the FastCGI cache when you add a specific word in the commit message:

if [[ {COMMIT_MESSAGE} =~ "flush-fastcgi" ]]; then
    {FLUSH_FASTCGI_CACHE}
fi

Additionally, you might have setup notifications that you do not want to notify in this case. We have a deploy script variable for that as well. Use the deploy script variable {DO_NOT_NOTIFY} inside your if statement to skip notifications.

An example:

if [[ {COMMIT_MESSAGE} =~ "skip-deployment" ]]; then
    echo "Skipping deployment upon commit message request."
    {DO_NOT_NOTIFY}
    exit 0
fi

Make sure to put the {DO_NOT_NOTIFY} variable before you exit the script.
