Checkout this approach for knowing what to transfer. This revision uses a local tag to track each time you use the command. The first time you use it, it pushes all files in the project. At the end of each run it updates the tag to point to HEAD. Next time you run it, it will only push files that have changed since the last push.

# Find out where HEAD is pointing
head_ref=$(git show-ref --head -s | head -n 1)
# Check to see if transmit tag exists, and get transmit tag hash
_transmit_ref=$(git show-ref --verify -s refs/tags/transmit)

# If there's not transmit tag, create it for the first time.
if [ $? -gt 0 ]; then
    # This won't work well for projects with multiple roots,
    # but for the typical case it will find the first commit
    # and tag that for the initial push.
    first_commit=$(git rev-list --max-parents=0 HEAD)
    echo 'Creating initial transmit tag'
    git tag -m 'Creating transmit tag' transmit $first_commit

# Find out where the tag is pointing
# @note Probably a cleaner way to do this ...
transmit_ref=$(git cat-file tag $_transmit_ref | head -n 1 | sed 's/^object //')

# If the transmit tag is the same commit as HEAD,
# there's nothing to do
if [ "$transmit_ref" == "$head_ref" ]; then
    echo 'No changes to push'
    exit 0

# Iterate over all the files that changed, adding then to Transmit 
echo 'Transmitting'
for i in $(git diff --name-only transmit HEAD); do
    if [[ -e "$i" ]]; then

Hi guys, for the motivation to this gist, please see this StackOverflow thread. Essentially, these are the commands you need to follow to install the script:

• save the script to your desktop as git-transmit (with no extension)
• cp git-transit /usr/sbin/
• cd /usr/sbin
• chmod a+x git-transmit
• Setup drop send for your live app
• Run git-transmit in your git repository.

Can I in someway specify a commit for upload? Usually have to a site already up and running and I would rather not upload it again, only my minor changes.

@jannejava That's the whole idea behind this script. It will only push what has changed since the last time you pushed.

On OSX 10.11.2 this is what I get, trying to copy the file to /usr/sbin/ (btw: there's a typo in your cp line @quickshiftin)

sudo cp git-transmit /usr/sbin/ 
cp: /usr/sbin/git-transmit: Operation not permitted 

Hi @reibejoy. It looks like need to use sudo.

Same problem as @reibejoy, solved using /usr/local/sbin/ instead.
