楼上的这个不行哦，要求中间的模块不重复，弄了半天很难弄，我只能生成下面的格式
production_3--p2p-user.jar 179
production_3--p2p-loan.jar 121
production_3--p2p-pay.jar 104
production_4--p2p-user.jar 184
production_4--p2p-loan.jar 116
production_5--p2p-user.jar 184
production_5--p2p-loan.jar 116
production_3--p2p-user.jar 179
production_3--p2p-loan.jar 121
production_3--p2p-pay.jar 104
production_4--p2p-user.jar 184
production_4--p2p-loan.jar 116
production_5--p2p-user.jar 184
production_5--p2p-loan.jar 116
production_3--p2p-user.jar 179
production_3--p2p-loan.jar 121
production_3--p2p-pay.jar 104
production_4--p2p-user.jar 184
production_4--p2p-loan.jar 117

回复 3# vipty sort -rn -k2 -t:
这个是可以重复的，只取:后面的做反向排序，就是最后的数字。
