How to Indent Command Output in PowerShell for Better Readability

When working with PowerShell, you'll often find yourself needing to run commands that output data directly to the console. While this can be very effective, the default formatting—and lack of indentation—can sometimes make your output hard to read. Specifically, if you're using commands like ping, you may want the results to be well-indented to improve visual appeal and clarity. If you've struggled with formatting your output, you're not alone! Let's dive into some solutions to achieve that clean, indented appearance you're after.

The Problem: Unformatted Ping Output

You might have executed a simple ping command intending to format its output neatly. However, you ended up with unformatted results that do not align or indent as you wish:

The output could look jumbled without proper indenting, making it difficult to read.

The Solution: Indenting Your Output

1. Directly Prefix Each Line with Whitespace

The first solution is simple: instead of using Out-String, use PowerShell's capability to manipulate each line directly. Here’s how you can do it:

This code executes the ping command and captures its output. The ForEach-Object cmdlet then prefixes each line with four spaces for indentation, making it visually clear.

2. Using Regular Expressions for Multi-line Strings

If the command outputs multi-line strings, or if you prefer the Out-String method, you can use the -replace operator with a regular expression to add leading spaces. Here's how:

In this example:

The -replace method coupled with the regex pattern (?<=^|\n) matches the position right after the beginning of the string or any new line.

The escape sequence `t inserts a tab at that position.

This approach works for both single and multiple lines, ensuring that every part of your output gets the necessary indentation.

Putting it All Together: Example Output

Say you run your ping command using the improved formatting approaches above. The output will now appear neatly aligned, looking something like this:

This formatting significantly enhances readability and helps convey the information more effectively.

Conclusion

Having well-formatted output in PowerShell, especially using commands like ping, can be crucial for readability. Whether you want simple line-by-line adjustments or are dealing with multi-line outputs, PowerShell provides the tools to customize how your command results are displayed. By following this guide, you can ensure your script outputs look clean, organized, and professional.

Happy scripting!
