Powershell script that highlights multiple search patterns in the output. You can give an array of regular expressions, every expression is marked in its own color.

I used this programming task to implement a ring buffer with a queue, clone the input pipeline, hand a variable of object type to a function per reference and save many programming lines by using recursion (no one seems to use recursion anymore). Just to see that it works and as a snippet container for me.

To use the function Write-Highlight, you have to dot source the function first, e.g. with: (assuming the script is in the current directory)

. .\Write-Highlight.ps1

Display the current directory and highlights all files that have a .ps1 or .bat extension.

Get-ChildItem | Write-Highlight "\w+\.ps1","\w+\.bat"

Display the current directory and highlights all files that have a .ps1 extension.

The complete directory listing is handed to the commandlet Sort afterwards.

Get-ChildItem | Write-Highlight "\w+\.ps1" -PassThru | Sort -Property Length

Every number in the output is highlighted with its own color.

1..10 | %{ "Line $_" } | Write-Highlight -Pattern "1","2","3","4","5","6","7","8","9","10"

All lines in the file "Write-Highlight.ps1" with the case sensitive expression "STRING" are given out, the expression "STRING" is highligthed.

gc .\Write-Highlight.ps1 | Write-Highlight "STRING" -Case -OnlyMatches
