A temporary file is created by TeamCity when you run add a Command Line Build Step with "Custom script" as runner.

The content of this file would be the <code>Custom script</code> you specified inside the user interface.
<a href="https://i.stack.imgur.com/wcvb1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wcvb1.png" alt="Custom Script build step"></a>

The produced output would be:

<pre><code>Step 1/1: Command Line (1s)
Starting: D:\TeamCity\buildAgent\temp\agentTmp\custom_script2362934300799611461.cmd

blocks|key|4978377|text|我看了一段时间，但TeamCity中似乎没有允许保存生成文件的配置变量。现在如果执行命令需要一些时间，例如超过几秒，你可以在资源管理器中打开临时目录，从构建开始的那一刻开始点击F5+(刷新)，直到你看到.cmd文件出现，然后快速右击它并选择“编辑”在文本编辑器中打开它。如果这太难了，您可以尝试使用here提供的解决方案:使用如下代码创建一个Powershell脚本：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4978378|$watcher+=+New-Object+System.IO.FileSystemWatcher
$watcher.Path+=+"D:\TeamCity\buildAgent\temp\agentTmp"
$watcher.Filter+=+"*.cmd"
$watcher.IncludeSubdirectories+=+$false
$watcher.EnableRaisingEvents+=+$true++
$action+=+{+$path+=+$Event.SourceEventArgs.FullPath
++++++++++++Add-content+"D:\log.txt"+-value+(Get-Content+$path)
++++++++++}++++
Register-ObjectEvent+$watcher+"Created"+-Action+$action
Register-ObjectEvent+$watcher+"Changed"+-Action+$action
while+($true)+{sleep+1}|code-block|syntax|javascript|4978379|然后运行它。当构建开始并创建cmd文件时，powershell脚本会将内容复制到d:\log.txt。不过，这仍然不适用于生命周期非常短的脚本。在这种情况下，我可以通过添加如下内容来延长脚本的使用时间|4978380|ping+127.0.0.1+-n+5+-w+1000+>+NUL|4978381|这将使它至少持续5秒。|4978382|entityMap|0|LINK|mutability|MUTABLE|url|https://superuser.com/questions/226828/how-to-monitor-a-folder-and-trigger-a-command-line-action-when-a-file-is-created^0|45|4|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@$A|X|B|Y|1|Z]]|C|$]]|$1|D|3|E|5|F|7|10|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|11|8|@]|9|@]|C|$]]|$1|K|3|L|5|F|7|12|8|@]|9|@]|C|$G|H]]|$1|M|3|N|5|6|7|13|8|@]|9|@]|C|$]]|$1|O|3|-4|5|6|7|14|8|@]|9|@]|C|$]]]|P|$Q|$5|R|S|T|C|$U|V]]]]

I looked around for a while but there seems to be no configuration variable in TeamCity allowing to keep generated files. Now if the commands executed take some time, e.g. more than a couple of seconds, you could just open the temp directory in explorer and start hitting F5 (refresh) from the moment a build is started until you see the .cmd file appear, then be quick and right-click it and select 'Edit' to open it in a text editor. If that is too hard you can try with the solution presented <a href="https://superuser.com/questions/226828/how-to-monitor-a-folder-and-trigger-a-command-line-action-when-a-file-is-created">here</a>: create a Powershell script with code like this:

<pre><code>$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "D:\TeamCity\buildAgent\temp\agentTmp"
$watcher.Filter = "*.cmd"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true 
$action = { $path = $Event.SourceEventArgs.FullPath
 Add-content "D:\log.txt" -value (Get-Content $path)
 } 
Register-ObjectEvent $watcher "Created" -Action $action
Register-ObjectEvent $watcher "Changed" -Action $action
while ($true) {sleep 1}
</code></pre>

and run it. When the build starts and creates a cmd file, the powershell script will copy the content to d:\log.txt. This will still not work for very short-lived scripts though. In that case I'd just make the script last longer by adding something like 

<pre><code>ping 127.0.0.1 -n 5 -w 1000 &gt; NUL
</code></pre>

which will make it last at least 5 seconds.

blocks|key|4978400|text|如果任何人仍然对此感到疑惑，您可以强制重新打开echo。作为自定义脚本中的第一件事|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4978401|@echo+on|code-block|syntax|javascript|4978402|这将撤消默认为teamcity的静默命令。|4978403|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In case anyone is wondering about this still, you can force echo back on.
Put as the first thing in the custom script

<pre><code>@echo on
</code></pre>

this will undo the silent commands teamcity defaults to.

I'm trying to dig into the depths of teamcity to get a better understanding of what its doing under the hood(and improve my own build knowledge). I noticed that when I run a build step it then executes its own .cmd which I presume wraps up the msbuild scripts. The problem is that whenever I look in the directory specified the file doesn't exist as I'm guessing it creates, executes then deletes almost instantly. Any suggestions on how to access the file? or what's inside?

我正在努力挖掘团队城市的深度，以便更好地了解它在幕后做什么(并提高我自己的构建知识)。我注意到，当我运行一个构建步骤时，它会执行它自己的.cmd，我认为它包装了msbuild脚本。问题是，每当我查看指定的目录时，文件都不存在，因为我猜它几乎是立即创建、执行然后删除的。对如何访问该文件有什么建议吗？或者里面是什么？Sta...
