How to put data into a file in Windows PowerShell?

You can use the "Set-Content" or "Add-Content" cmdlet to put data into a file in Windows PowerShell.

The "Set-Content" cmdlet is a string-processing cmdlet that writes or replaces the content in the specified item, such as a file. You can type the content in the command or send content through the pipeline to Set-Content.

The "Add-Content" cmdlet appends content to a specified item or file. You can specify the content by typing the content in the command or by specifying an object that contains the content.

Example 1: The following command replaces the contents of all files in the Test1 directory that have names beginning with "test" with "Hello, World".

PS C:\fyicenter> Set-Content -Path C:\Test1\test*.txt -Value "Hello, World"

Example 2: The following command replaces the contents of the final.xml file with the contents of the test.xml file. The command uses the Force parameter so that the command is successful even if the Final.xml file is read-only. It uses the Encoding dynamic parameter to specify an encoding of UTF-8.

PS C:\fyicenter> Get-Content test.xml | Set-Content final.xml -Force -Encoding UTF8

Example 3: The following command adds "END" to all text files in the current directory, except for those with file names that begin with "help."

PS C:\fyicenter> Add-Content -Path *.txt -Exclude help* -Value "END"
