#!/usr/bin/env bash

if [[ ($# -ne 1) && ($# -ne 2) ]]
then
    echo "usage is $0  [ or, if missing, current dir]"
else
    REG_EXP=$1
    DIR=${2:-.}
    if [ ! -d $DIR ]; then
        echo "directory [$DIR] does not exist";
        exit 1;
    fi
    find "$DIR" -name "*.jar" -exec sh -c '
    (test -e {})
    exitStatus=$?
    if [ "$exitStatus" -eq 0 ]; then # this is done to avoid broken symlinks
        jar -tf {}|grep -i -H --label {} '$REG_EXP'
    fi
' \;
fi
