Running multiple admin clients
While running a multi-site contest with centralized server control, there was a need for some contest administrators to run multiple administrative clients out of a single PC^2 directory without creating multiple versions of pc2v8.ini and swapping between them before connecting to each site. A bash script (below) was created to prompt for the target site then to edit the pc2v8.ini file, inserting the site specific details. After using that for a short while, A bit more code was added to provide the capability to start any of the client modes of PC² from the script.
This code has not been extensively tested.
The environment variables JAVAHOME and PC2HOME should be edited to reflect your environment, as well as the site names and their corresponding IP addresses. A version of GNU sed that supports in-place editing as well as extended regular expressions is required. The regular expressions used here are greedy so as to be more "universal" and could be made simpler by inserting known characteristics of the data that will be used by your site.
The script mainly consists of two select/case structures, where the first prompts the user for the target server then uses sed to alter pc2v8.ini appropriately. The second select/case structure prompts the user to select the client function that they wish to invoke, then runs the relevant command.
Example Shell Script
Note: This sample script is not supported by the PC² Team, also it is clear that a user would be required to modify this script to make it it work, as opposed to relying upon a properties/config/ini file for the server contact data (IP and port).
