什么是Windows使用DOS批处理程序的原因是什么？ [英] What are the reasons to use dos batch programs in Windows?

问题描述

问

什么是相对于下载一个很好的（理想情况下，技术）的理由永远编程一个在现代Windows系统上DOS批处理语言中的一些不平凡的任务或者PowerShell或ActiveState公司的Perl？

What would be a good (ideally, technical) reason to ever program some non-trivial task in dos batch language on a modern Windows system as opposed to downloading either PowerShell, or ActiveState Perl?

要更具体地，我使这个问题的持续时间以下两种假设：

To be more specific, I make the following two assumptions for the duration of this question:

• 任何人足够的技术，能够写一个中等复杂批处理脚本是足够的技术来安装这脚本间preters的。

• anyone technical enough to be able to write a medium-complexity batch script is technical enough to install either of the scripting interpreters.

无论这两个present足够提到曲线将超过批量做任何远程-不平凡的任务的疼痛基本批量更换任务的学习曲线的。

Neither of those two present enough of a learning curve for basic batch replacement tasks that said curve would outweigh the pain of doing any remotely-non-trivial task in batch.

备注

• 你需要AUTOEXEC.BAT批处理程序不是一个充分的理由。您的AUTOEXEC.BAT也许仅仅是调用非批处理脚本。

• "You need a batch program for autoexec.bat" is not a valid reason. Your autoexec.bat may consist of simply calling non-batch script.

如果您有任何的我的上述2假设不同意，那很好，我可能是错的。但我的问题是明确假设那些2假设是正确，这将是仍然有一批坚守的原因吗？如果它可以更容易暂停怀疑（如果你不同意我），加入第3假设问题仅限于谁已经posess至少有一些PowerShell的或Perl些许经验的人。

If you disagree with either of my 2 assumptions above, that's fine, and I may be wrong. But my question is specifically "assuming those 2 assumptions are correct, what would be the reason to still stick with batch?" If it makes it easier to suspend disbelief (in case you disagree with me), add in a 3rd assumption that the question is limited to people who already posess at least some modicum of PowerShell or Perl experience.

再次重申 - 这并不意味着是它是多么容易学习PSH或ASPerl相比，做先进的批号打码一个主观的问题。这是一个单独的问题是太主观，在这个帖子被人打扰。

To re-iterate - this is not meant to be a subjective question about how easy it is to learn PSh or ASPerl compared to doing advanced batch coding. That is a separate question that is too subjective to be bothered with in this post.

背景

我用来做一些相当复杂的批处理编程回到老日子，记住批次，因为我曾遇到的最糟糕的编程语言之一。

I used to do some fairly complicated batch programming back in the elder days, and remember batch as one of the worst possible programming languages I had encountered.

有关这个问题的想法，看见一堆的SO批次的问题，并试图神交其中一人回答出来的纯粹的好奇心，一分钟后，在痛苦中放弃后传来，精神上感叹为什么会有人经过这种痛苦的，而不是做，在1号线的Perl？ ：）

The idea for this question came after seeing a bunch of batch questions on SO, and trying to grok the answer of one of them out of sheer curiosity and giving up in pain after a minute, exclaiming mentally "why would anyone go through this pain instead of doing that in 1 line of Perl?" :)

我自己的答案似是而非

我认为有可能是一个可能的兼容DOS系统，其中有DOS间preTER但没有兼容的PowerShell或Perl ...我不知道一但并非完全不可能的。

I assume there may be an an likely DOS-compatible system, which has DOS interpreter but has no compatible PowerShell or Perl... I'm not aware of one but not completely impossible.

推荐答案

通常情况下，理由是，你需要的脚本不具有另一种间preTER并在其上是不允许的机器上运行安装一个跨preTER。在许多公司生产的服务器是一个很好的例子 - 你希望他们有尽可能少的开发载体成为可能，这意味着不需要对应用程序的功能没有任何的脚本语言

Typically, the rationale is that you need the script to run on a machine which does not have another interpreter and on which you are not allowed to install an interpreter. Production servers in many companies are a good example -- you want them to have as few exploitation vectors as possible, which means no scripting languages that are not required for application functionality.

您说的没错，当你说这个批处理语言是一个可怕的语言 - 有他们沉没的时间和资金投入到建设PowerShell的一个原因 - 但它也可以跨的无数版本依靠唯一的通用语言Windows操作系统。

You're right when you say that the batch language is a terrible language -- there's a reason they sunk the time and money into building PowerShell -- but it's also the only universal language you can rely on across the myriad versions of Windows.
