Rundeck File Lookup Plugins
This plugin provides utilities to read data from the filesystem into Rundeck step data.
Scan File Step Plugin
Scans a file for a regular expression pattern. If the specified pattern has one replaceable field, the scan stops on first match for performance reasons. If the pattern has two capture fields, the scan will go to the end of the file and the last value for matches will be returned.
JSON Lookup Step Plugin
Finds the first matching key in a JSON file.
