Minify with YUI shell script

minify.sh

# src: http://www.craig-russell.co.uk/bulk-minify-shell-script/

CSS='css'
JS='js'
FILELIST="minify.$$.tmp"
COMPORESSOR="yuicompressor-2.4.2.jar"
MINCSS="css/styles.min.css"
 
# Minify CSS to single file
echo -n '' > $MINCSS
ls $CSS | grep -v min > $FILELIST
while read LINE
do
    OLD="$CSS/$LINE"    
    echo "$OLD -> $MINCSS"
    java -jar yuicompressor-2.4.2.jar $OLD >> $MINCSS #bug fix: fix media queries   
done < $FILELIST
 
# Minify JS to multiple files
ls $JS | grep -v min > $FILELIST
while read LINE
do
    OLD="$JS/$LINE"
    NEW=` echo "$JS/$LINE" | sed 's/\.js/.min.js/g'`
    echo "$OLD -> $NEW"
    java -jar yuicompressor-2.4.2.jar $OLD > $NEW    
done < $FILELIST
 
rm -f $FILELIST

You might want to protect the dot in your sed like this :

sed 's/\.js/.min.js/g'

to avoid mainjs.js >> mainmin.js.min.js
