About CLISnippets.com
This idea came from a post on the Self Managed WordPress (by GridPane) Facebook group. The group was sharing snippets, and we (Sentree) felt this could be a valuable resource to record and expand upon. These work great with Termius Snippets, but can be used directly or in many other tools.
