easy node and node-global debugging. 2 functions for your .bashrc

debug-node

# put these in your ~/.bashrc and start a new shell to receive these commands
# requires node-inspector, install: npm install -g node-inspector

# start node-inspector and debug node app
# example: debug-node --open app.js --port=3000
function debug-node () {
    # start node-inspector as a background-process
    node-inspector &
    # grab last PID to kill process later
    INSPECTOR_PID=$!
    # optionally open in browser
    if [ $1 = "--open" ]; then
        open "http://localhost:8080/debug?port-5858"
        shift
    fi
    # next arg should be the name of the global app i.e. "grunt"
    APP=$1
    shift
    # find the app in path with which, forward next args
    node --debug-brk $APP $@
    # kill node-inspector when done
    kill $INSPECTOR_PID
}

# example: debug-node-global --open grunt jshint
# debug a node cli app with node-inspector
function debug-node-global () {
    # start node-inspector as a background-process
    node-inspector &
    # grab last PID to kill process later
    INSPECTOR_PID=$!
    # optionally open in browser
    if [ $1 = "--open" ]; then
        open "http://localhost:8080/debug?port-5858"
        shift
    fi
    # next arg should be the name of the global app i.e. "grunt"
    APP=$1
    shift
    # find the app in path with which, forward next args
    node --debug-brk $(which $APP) $@
    # kill node-inspector when done
    kill $INSPECTOR_PID
}
