Background[ edit ] Every version of Microsoft Windows for personal computers has included a command line interpreter CLI for managing the operating system. Both support a few basic internal commands. For other purposes, a separate console application must be written.
I was recently assigned a very simple task: Drag and drop, yeah? The biggest problem is not even the speed. What if the copy operation partly fails? There is no way of telling which files were copied and which were not.
It is also worth mentioning that one of the requirements was to build a tool that can be used by end users to repeat process. For instance, if somebody changed already-copied files while the rest were still copying, the tool needs to be able to run an incremental sync at some point.
First, I thought about utilizing robocopy. It is a very nice utility with a lot of options. Another problem was that there is no obvious way to log information about failed copies only. There is verbose logging, which is nice, but the last thing I needed were hundreds of thousands of lines to analyze.
I then decided to try the Copy-Item PowerShell cmdlet. This is a great tool, except it cannot always copy opened files and is not good with incremental copying.
Finally, I remembered the old, faithful xcopy utility that has always worked for me, even way before Microsoft rolled up PowerShell. However, it does not have the logging capabilities I needed.
Thus, I decided to use xcopy in combination with PowerShell. Below is the script I used for my copy task. I will explain how it works below.
If the files and folders in the destination location already exist, the script performs an incremental copy. Every item that was changed before the copy process started will be copied to the destination. The error log file is created and populated with errors that occurred during the copy process, if any.
If omitted, it will save logs to the c:I have a script I created that contains considerable output to the console using Write-Host.
I start a transcript at the beginning of the script and all output from Wrote-Host is contained in the transcript grupobittia.coms: 9.

Mar 06, · Both version 1 and version 2 of Windows PowerShell have a nasty limitation when it comes to capturing *all* output from a script.
First up, within a script there is no way to redirect host (Write-Host), verbose, warning and debug message to a log file. Show output on screen and in file in PowerShell. Ask Question.
The Tee-Object cmdlet enables you to display data in the Windows PowerShell window and to save that same data to a text file, all with a single command. Return log output and result object from cmdlet.

Sep 24, · Summary: Use the Windows PowerShell cmdlet, Select-String, to view the contents of a log file. Hey, Scripting Guy!
I have a log file that I created by dumping process information from Get-Process. It is quite long, and I am trying to use Select-String to find the number of instances of a certain process.
