Windows 7 防止在PowerShell输出文件中换行的命令行语法？

下面的命令将输出包装到调用脚本的窗口的宽度。也就是说，输出文件是“word”包装的。如何在不修改脚本的情况下防止输出文件中出现这种包装

PS C:\Users\User1> & '\\fileServer\c$\PowerShell Scripts\herScript.ps1' > output.txt

试试这个（我无法测试）

您可以使用

设置内容

而不是使用

（即

输出文件

），使用写入主机cmdlet作为管道的最后一条语句。正常的未经修饰的powershell输出显示为查看父控制台窗口的尺寸，并将输出行修剪/包装为宽度-1。Write-Host cmdlet绕过此步骤，直接写入stdout而无需任何进一步的修改

下面是一个示例，它读取JSON文件，并编写javascript输出，将JSON添加到一个大字符串中（保留注释）：

以及使用写入主机时的输出：

manifestBlob += "\n";
manifestBlob += "//  File: manifest.json\n";
manifestBlob += "//\n";
manifestBlob += "//  Description:\n";
manifestBlob += "//      manifest for chrome plug-in\n";
manifestBlob += "\n";
manifestBlob += "{\n";
manifestBlob += "    \"manifest_version\": 2,\n";
manifestBlob += "\n";
manifestBlob += "    \"version\": \"0.0.0\",\n";
manifestBlob += "\n";
manifestBlob += "    // the ID is: sdfjkghsdfjkghjksdfghjkfhjkdfjff\n";
manifestBlob += "    \"key\": \"sdfjkhsdfjkghjksdfghkjsdhgsdjkgfhjklsdfhgjklsdfhgjklsdhfgkljsdfhgkljsdhklgjsdhfjklghsdfjklghsdjklfghjksdfhgjksdhfgjklhsdfjkl\",\n";
manifestBlob += "\n";
manifestBlob += "    \"content_scripts\": [ { \"matches\": [\"http://*/*\", \"https://*/*\"], \"js\": [\"content.js\"], \"run_at\": \"document_start\" } ],\n";
manifestBlob += "\n";
manifestBlob += "    // this is the standard LOCAL install location - but if this extension is published to the app-store, this value gets overridden (that is okay and even good)\n";
manifestBlob += "    \"update_url\": \"file:///C:/Program%20Files/MyProduct/Update.xml\",\n";
manifestBlob += "}\n";

最后一个例子是，如果不使用Write-Host cmdlet（假设控制台宽度为60），会发生可怕的事情：

---

Out文件

也有一个

-Width

参数。它的文档说明宽度以外的所有内容都被截断（而不是包装）。所以我猜这会先截断4096个字符（这是一个奇怪的非整数），然后截断控制台窗口的宽度。虽然它不会换行，但它会截断可能不需要的较长的行。4096不是奇数，也不是非圆的。2^12

-Width

参数似乎无法阻止换行。在

输出文件

之前的管道中注入

输出字符串-宽度xxx

，对我来说确实起到了作用。警告选择器：

设置内容

的行为有所不同。重要的是（但没有文档记录）它会锁定文件，使其无法读取。因此，

设置内容

对于日志记录来说是一个糟糕的选择。当我使用Write Host时，看不到任何重定向到文件的内容。PowerShell 5.1。
