Add-Content in PowerShell

Add-Content in PowerShell

The Add-Content cmdlet in PowerShell is used to add new content to the end of a file. This cmdlet takes the path and name of the file as input, and the content to be added to the file as an argument. It then appends the specified content to the end of the file.

Examples

Example 1: Add text to the end of a file

For example, to add the text "This is a new line of text" to the end of a file named "myfile.txt" in the current directory, you can use the following PowerShell command:

Add-Content "myfile.txt" "This is a new line of text"

This command will add the specified text to the end of the "myfile.txt" file in the current directory.

If the file does not exist, it will be created automatically.

If the file already contains other content, the new content will be added after the existing content.

Example 2: Add a newline or multiple lines

To add a new line to a file using the Add-Content cmdlet in PowerShell, you can use the `n escape sequence to represent a new line.

This escape sequence tells PowerShell to insert a new line at the specified location in the content being added to the file.

For example, to add the text "This is the first line" and "This is the second line" to a file named "myfile.txt" in the current directory, with each line appearing on a separate line in the file, you can use the following PowerShell command:

Add-Content "myfile.txt" "This is the first line`nThis is the second line"

Conclusion

The Add-Content cmdlet is useful for adding new information to an existing file without overwriting or modifying the existing content. It is commonly used in PowerShell scripts and automation tasks to update files with new data or information.
