Victor's macOS Client information parser

README.md

1. Download the client-information and move it to /usr/local/bin/client-information:

   wget https://gist.githubusercontent.com/frdmn/5eeebc05c61c7a00450aee8b81be824c/raw/520d3e9ae9ec80710344119e1780939fa843130b/client-information -O /usr/local/bin/client-information
   bash +x /usr/local/bin/client-information
   

2. Configure the scheduler to periodically run the script:

   wget https://gist.githubusercontent.com/frdmn/5eeebc05c61c7a00450aee8b81be824c/raw/520d3e9ae9ec80710344119e1780939fa843130b/victor.client-information.plist -O ~/Library/LaunchAgents/victor.client-information.plist
   

3. Enable the LaunchAgent scheduler:

   launchctl load ~/Library/LaunchAgents/victor.client-information.plist
