若要複製檔案,請將新的 -FromSession 和 -ToSession 參數值指定為 PSSession 識別碼,並新增 -Path 和 -Destination 以分別指定原始路徑和目的地。 例如,Copy-Item -Path c:\myFile.txt -ToSession $s -Destination d:\destinationFolder。 Windows PowerShell 轉譯已經過改良,因此它不僅能套用至主控台主機 (...

Similarly, the $ symbol can be used to indicate the end of a string. This wouldn't be very useful in the case of a UNC path since a UNC path can contain additional path segments, such as \\Server2\Share\Folder\File, for example. However, I'm sure there are many cases where you ...
事实证明在操作上重定向和Out-File非常的类似:当PowerShell转换管道结果时,文件的内容就像它在控制台上面输出的一样。Set-Content稍微有所不同。它在文件中只列出目录中文件的名称列表,因为在你使用Set-Content时,PowerShell不会自动将对象转换成文本输入。相反,Set-Content会从对象中抽出一个标准属性。上面的情况下,...
