Simple alternative to using gulp/grunt to build CSS using Less

css.sh

#!/usr/bin/env bash

function css_build {
    echo "Starting build..."
    lessc --verbose ./less/main.less ../assets/css/app.css
    echo "Completed at `date +%H:%I:%S`"
}

function css_watch {
    echo "Building CSS on changes (CTRL+C to stop)"
    while true
    do
        css_build
        inotifywait -e modify -e move -e create -e delete -r less > /dev/null 2>&1
    done
}

if [[ $1 == "build" ]];
then
    css_build
else
    css_watch
fi
