gmcpda-guard/scripts ? reverse-engineered prompt

I want a small set of shell scripts that help me manage a bunch of git repos from the command line.

One script should update a repo or a folder of repos, pulling the latest changes and showing clear messages if anything fails. Another should push changes to all the repos I point it at, so I do not have to open each one by hand. I also want a simple script that tells me who is currently connected to the machine, in a human readable way.

Keep the scripts easy to run, safe by default, and clear about what they are doing before they make changes. Make them work on a normal Mac or Linux terminal, and if you need to check current command behavior or options online, feel free to do that.
