python实现批处理文件
本文实例为大家分享了python实现批处理文件的具体代码，供大家参考，具体内容如下
Windows下的bat,linux下的shell用来做批处理都很好用，可惜不通用
用Python来做就简单多了，不过一条条写代码来调用系统命令也够烦的了
程序员都很懒,不愿做机械无谓的重复性工作,干脆自己实现一个.
用法超级简单,默认会执行一个自定义的batch.json,按顺序一条条执行其中的步骤
{"steps":
[
{"step":"df-h","desc":"displaydiskspaceusage"},
{"step":"date","desc":"displaythecurrentdater"},
{"step":"time","desc":"displaythecurrenttime"}
]
}
用法：
pythonbatch.py
当然也可以指定不同的步骤文件,例如
pythonbatch.pyxxx.json
运行结果以markdown形式输出,例如
$pythonbatch.py Usage:pythonbatch.pynote:executethebatch.jsonbydefault #Executebatch.jsonbegin --------------------------- ##Willexecute3steps ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 0.[df-h]:displaydiskspaceusage 1.[date]:displaythecurrentdater 2.[time]:displaythecurrenttime *0.[df-h]:displaydiskspaceusage FilesystemSizeUsedAvailCapacityiusedifree%iusedMountedon /dev/disk1233Gi208Gi24Gi90%54622825636469490%/ devfs329Ki329Ki0Bi100% *1.[date]:displaythecurrentdater ThuMar322:50:21CST2016 *2.[time]:displaythecurrenttime real0m0.001s user0m0.000s sys0m0.000s ##Donethefollowingsteps ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 0.[df-h]:displaydiskspaceusage 1.[date]:displaythecurrentdater #Executebatch.jsonend.
Python源代码如下,希望有人能用得上
