Node run sh script does not run correctly

Hi there i am trying to run a sh script I wrote and fire it from a javascript file I have.

I seem to find the file and execute but not everything. If you take a look here at a section of .sh file

# Add files from public folder
# Get commit desciption message 
# Commit changess 
git add public/* 
if [ "$(git diff ${BRANCH} -- ${SRC} --quiet --exit-code --cached)" ]
then
    echo "line 1"
    read -p "${BLUE}Commit description: ${RESET}" desc 
    git commit -m "$desc" -- public

    echo "line two"
    read -p "Do you want to push these commits? [y]/n " -n 1 -r
    echo
    if [[ $REPLY =~ ^[Yy]$ ]]
    then
        pushing
    else
        echo "${RED}Push canceled. Goodbye!${RESET}"
    fi
else
    echo "${RED}Noting to commit. Goodbye!${RESET}"
fi

It works all the way down as far as the first read command where it then freezes. I have tried removing colours ect.

To execute I have tried both shellJs and using child process like so,

var exec = require('child_process').exec, child;
var testscript = exec('sh tools/publish.sh /tools');

testscript.stdout.on('data', function(data){
    console.log(data);
});

testscript.stderr.on('data', function(data){
    console.log(data);
});

Both shellJs and this method get the same result it print "line one then freezes.

Can someone help with this would be great. If you need to see more code just let me know thanks.
