XFacebookLinkedIn Set-Content is one of those core PowerShell cmdlets that I can't do without. I still remember using VBscript before we could use PowerShell to write to a file. I remember always trying to remember what kind of object I needed to use and the method name. Was it FileSystemObject, FileObject or what? It was a pain! Even when I did recall the method name was CreateTextFile(), I'd always forget to add True as the second argument. Here's an example of the monstrosity I'm talking about. Set objFSO=CreateObject("Scripting.FileSystemObject") outFile="c:\file.txt" Set objFile = objFSO.CreateTextFile(outFile,True) objFile.Write "test string" objFile.Close Compare that VBScript with this PowerShell: Set-Content -Path 'C:\file.txt' -Value 'test string' Which one do you prefer? I'll take the PowerShell way! The PowerShell way uses a single cmdlet called Set-content. This cmdlet allows us to much more easily use PowerShell to write to a file. This PowerShell cmdlet is a built-in cmdlet that has one purpose; to write to a file. It may have some parameters here and there to change up that behavior a bit, but it's solely focused on writing to a file. Not to be confused with Add-Content though since they are similar. Set-Content overwrites the entire file while Add-Content adds to a file. I learned that one the hard way multiple times when I first got started! ## Creating a File/Overwriting a File The Set-Content cmdlet is fairly simple. Below is a good example. This example shows that Set-Content can both create a file if it doesn't exist or it can replace all of the contents inside of a pre-existing file. PS> Test-Path -Path C:\test.txt False PS> Set-Content -Path C:\test.txt -Value 'foo' PS> Get-Content -Path C:\test.txt foo PS> Set-Content -Path C:\test.txt -Value 'bar' PS> Get-Content -Path C:\test.txt bar ## Output to a File One cmdlet that can output to a file is [Out-File](https://adamtheautomator.com/out-file/), but Set-Content can perform the same task albeit a little differently. Perhaps you'd like to pull specific pieces of text from one text file and output lines to another file. By using Get-Content and Set-content, you can make this happen. Maybe I've got a text file with one server and their status per line. I'd like to read each server's status and output that to a file. Using Get-Content to read the file and Set-Content to write to file, it's possible. PS> Get-Content -Path C:\test.txt SRV1 Status: Up SRV2 Status: Down SRV3 Status: Up PS> Get-Content -Path C:\test.txt | ForEach-Object { >>> $srvName = $_.Split(' ')[0] >>> Set-Content -Path "C:\$srvName.txt" -Value $_ } PS> [Get-ChildItem](https://adamtheautomator.com/get-childitem/) -Filter 'SRV*' Directory: C:\ Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 10/29/2017 12:38 PM 17 SRV1.txt -a---- 10/29/2017 12:38 PM 19 SRv2.txt -a---- 10/29/2017 12:38 PM 17 SRV3.txt PS> Get-ChildItem -Filter 'SRV*' | Get-Content SRV1 Status: Up SRV2 Status: Down SRV3 Status: Up Set-Content is one of those core cmdlets that gets used constantly. It's not fancy but works every time and is one you should have in your PowerShell bag of tricks.
