Simple Reloading Server in Bash

Tuesday, August 5th 2014

It’s often extremely useful to have a server that automatically reloads when any of the source files change. Grunt is commonly used for this, but in some cases that is overkill - a simple bash script will suffice. The script below uses Python 2 to start the server and inotify-utils to wait on changes in a directory.

set -e

# Create site dir if it does not exist
mkdir -p site

# Python server
cd site
python -m SimpleHTTPServer &
cd ..

# Kill python server on exit
trap "exit" INT TERM
trap "kill 0" EXIT

while true; do
  echo "Building site..."
  sass theme/styles.scss:theme/styles.css

  echo "Waiting for changes..."
  inotifywait -e modify -r .
