This powershell cmdlet continuously monitors a directory tree and write to the output the path of the file that has changed.

This allows you to create an script that for instance, run a suite of unit tests when an specific file has changed using powershell pipelining.

Installation

Download the psm1 file in My documents\WindowsPowershell\Modules\pswatch or simply run this one line installation script:

iex ((new-object net.webclient).DownloadString("http://bit.ly/Install-PsWatch"))

Usage

A simple example will be:

Import-Module pswatch

watch "Myfolder\Other" | %{
	Write-Host "$_.Path has changed!"
	RunUnitTests.exe $_.Path
}

You can filter by using powershell pipelining as follows:

watch | Get-Item | Where-Object { $_.Extension -eq ".js" } | %{
	do the magic...
}
