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.
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"))
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...
}
The wacth cmdlet has the following parameters:
- location: the directory to watch. Optional, default to current directory.
- includeSubdirectories: default to true.
- includeChanged: default to true.
- includeRenamed: default to true.
- includeCreated: default to true.
