You type a command — PowerShell gives you the output it thinks you want. If the default output is not what you need, use the formatting cmdlets like Format-Table and Format-List to get what you want. But sometimes, what you want is getting output to a file, not to the console. You might want to run a command or script that outputs information to a file and sends this file via email or possibly FTP.

Or, you might want to view it in a text editor or print it out later. Once you have created the code script, fragment, or a single command that creates the output you need, you can use several techniques to send that output to a file.

Writing this reminds me of my friends in Portugal who tell me there are ways to cook bacalao cod. Then they whisper: plus the way my mother taught me.

If there are more techniques for file output, I expect to see them in the comments to this article. The two cmdlets you use to send command or script output to a file are Set-Content and Add-Content.

Both cmdlets convert the objects you pass in the pipeline to strings, and then output these strings to the specified file. For example:. In many cases, this conversion does not produce what you expect or want. In this example, PowerShell found the 5 pwsh. Wildcard characters are not accepted.

Specifies that the content written to the file does not end with a newline character. The string representations of the input objects are concatenated to form the output.

No spaces or newlines are inserted between the output strings. No newline is added after the last output string. Specifies the number of characters in each line of output. Any additional characters are truncated, not wrapped. If this parameter is not used, the width is determined by the characteristics of the host. The default for the PowerShell console is 80 characters. To send a PowerShell command's output to the Out-File cmdlet, use the pipeline. Alternatively, you can store data in a variable and use the InputObject parameter to pass data to the Out-File cmdlet.

Out-File saves data to a file but it does not produce any output objects to the pipeline. Skip to main content.
