In a previous tip we showed you how to add your own little code snippets to the new PowerShell ISE v3 script editor. Here's how you can get rid of code snippets:
Get-ISESnippet returns all snippets that you registered previously with New-ISESnippet. Actually, the snippets returned are XML files. You can pipe them to Remove-Item to remove them. This would remove ALL custom snippets
Get-ISESnippet | Remove-Item
If you want to just delete a particular snippet, you could use an approach like this:
PS> dir (Join-Path (Split-Path $profile) 'Snippets') Tr* Directory: C:\Users\Tobias\Documents\WindowsPowerShell\Snippets Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 02.07.2012 00:04 966 Trap.snippets.ps1xml
This would list only snippets that start with "Tr". Pipe the results to Remove-Item to delete these snippets.
