add an option: pjRecompileCMD
abandon the ugly fileName, filePathWithN variable names
really painful. Can python really interact well with shell? I just can not make a stupid combined shell command work.
Kind of painful,but finally get it works.I switched back to use bash shell and makes it work,but I found bash shell didn't support using global arrays in functions.Therefore,I switched back to Python again, and this time I made it work.
