function getAllFiles()
{
        fileList=`ls $FilePath`;
        for fileName in $fileList;
        do
           #if test -f $fileName; then
           if [-f $fileName ];then
              echo $fileName;
           elif test -d $fileName; then
              cd $fileName;
              FilePath=`pwd`;
              getAllFiles;
              cd ..;
           else
              echo "$FilePath is a invalid path";
           fi
        done
