The other cool thing about Windows PowerShell is that in the end, if something runs without errors and something does what you need to be done, it is a solution. If I can write a bit of code in five minutes that is ugly but works, it is probably better than something that is elegant but takes me five hours to write. On the other hand, there is something to be said for thinking about how to do things more effectively in Windows PowerShell.
GM, I am imagining that your approach was to do something like this:. This command does not work the way you want it to work … in fact, it does not really work very well at all because it does not produce the expected results. You are getting hung up with wrestling with the pipeline, getting confused with the Foreach-Object cmdlet that is interrupting your pipeline , and messing about with the Export-CSV command that is not producing a CSV file at all.
While it is true that Windows PowerShell has some pretty cool cmdlets for working with CSV and for working with files, it is also true that at times, I want to be able to read the entire contents of a file into memory, and work on it at one time. The Get-Content cmdlet does not permit this; it basically creates an array of lines of text, which is great on most occasions.
To easily read the contents of a file all at once, I use the readalltext static method from the File class from the. NET Framework. The File class resides in the System. NET Framework namespace. When using this class, I use square brackets around the class and namespace name. I can leave off the word system if I want to, or I can type it if I wish—it does not matter. If the word system is not present, Windows PowerShell will assume that the namespace contains the word system in it and will automatically use that when attempting to find the class.
NET Framework namespaces are similar to the namespaces used in WMI because they are used to group related classes together for ease of reference.
The difference is that the. NET Framework namespaces are a bit more granular. Therefore, if I am interested in working with files, directories, paths, file information, and other related items, I would go to the System. NET Framework namespace and look around to see what is available. And it works. Many times, the things a class provides are available somewhere else.
For example, the File. NET Framework class provides a static method called exists. This method returns a Boolean value true or false that lets me know if a file exists or not. To use this method, I provide a string to the method. This technique is shown here:. Network policy with processing order 2 or above is not getting executed. Skip to main content.
Find threads, tags, and users T has the same issue. Current Visibility: Visible to all users. This should work. Double check the quotes and brackets to make sure that I got it right. Okay, I came here looking for PowerShell too, but I almost got suckered into taking up the "there was no good way to do this [in batch]" challenge.

Daniel Liuzzi I would like to add that testing the solutions provided out all worked, but this one was the easiest for readability. I was able to hand this to a co-worker and he could easily understand what was going on. Thanks for the assistance. For this to work in files in subdirectories, you need ".
Interestingly, when I tried to make this work without a around get-content it failed at write-content because the file was locked. Artyom don't forget the. Got stung by that myself. You can add -File filter to the Get-ChildItem Took a while to figure it out — Amir Katz. Show 9 more comments. Don't forget the parenthesis -- without which you will receive an access error.
