Deploy a jekyll site to a s3 bucket including gzip compression of html/js/css files

# Deploy a jekyll site to a s3 bucket with gzip compression of html/js/css files
#
# To use - place in your root directory of your jekyll 
# site, and edit the BUCKET="<YOUR_S3_BUCKET>" variable at the top
# to reflect the S3 bucket you're uploading to.
#
# You will need to have jekyll, and s3cmd already setup 
# (and it relies upon standard *nix utilities like find,
# egrep, xargs and gzip)

BUCKET="pv.tl"

#remove old site
rm -rf ./_site/

#generate site
jekyll build

#compress html/css/js files (-n removes the timestamp)
find _site | egrep "\.(html|js|css)$" | xargs -I{} gzip -n -9 {}

#remove the .gz extension
find _site | egrep "\.(html|js|css)\.gz$" | xargs -I{} bash -c 'FILE="{}"; mv ${FILE} ${FILE%.*}'

#upload non-compressed files
s3cmd -P sync --no-preserve --exclude '*.html' --exclude '*.css' --exclude '*.js' _site/ s3://$BUCKET/

#upload compressed files
s3cmd -P sync --no-preserve --exclude '*.*' --add-header='Content-Encoding: gzip' --include '*.html' --include '*.css' --include '*.js' _site/ s3://$BUCKET/

#remove removed files
s3cmd -P sync --delete-removed _site/ s3://$BUCKET/
