Checkmk Werk 15107: Extension packages: modernise command line interface

by Moritz Kiemer

ID: 15107 Title: Extension packages: modernise command line interface Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 We recently added new features to the extension packages (a.k.a. MKPs) manager. These changes require some adjustments and modernisations of the commandline interface to get a consistent user experience. The following changes are made to the commandline interface <tt>mkp [COMMAND]</tt>: <tt>find</tt>: The find command now reports some details for each file. If you are using the command in a script, we recommend setting the new <tt>--json</tt> flag, and pipe the output through the commandline tool "<tt>jq</tt>". To get a list of all local files, for instance, use "<tt>mkp find --json --all | jq .[].file </tt>".
