1. # unjar all jar files found in $JARFILES into $CLASSES:

    export CLASSES=~/unjarred;
    export JARFILES=.;
    mkdir -p $CLASSES;
    cd $CLASSES;
    find $JARFILES -name \*jar -exec jar -xf {} \; 

2. # recursive decompilation of all class files in $CLASSES, storing their decompiled version in $DECOMPILED:

    export CLASSES=~/unjarred;
    export DECOMPILED=~/decompiled;
    cd $CLASSES;
    mkdir -p $DECOMPILED;
    find -name \*class -exec jad -b -dead -o -s java -safe -ff -lnc -r -d $DECOMPILED {} \;
