First - Thanks for this script!

Second, weirdly on my M1 I'm getting both 12.4 and 12.5 of the command line tools showing up. LOL. But softwareupdate won't let me run the 12.4 (obviously). Another Big Sur (intel) machine only shows 12.5. Very weird. I may see if I can figure out how to choose the 'last' option if multiple are given, assuming that's the latest. I might even try to figure out how to grep the versions and test that to choose. But that all makes my head spin. :-p

FWIW I was using this to install on an old Mojave Mac mini over ssh. softwareupdate didn't recognize the -v option so I had to remove it for it to run.

Still, thanks for the help :-)

Thank you for the code. I had to modify this slightly for it to run on Monterey 12.0.1. I have not regression tested this but it would be simple to check the OS version and use your original code for versions prior to Monterey (if this code doesn't work for them).

Thanks for this! Had same issue of needing to install over ssh over vpn, so no chance to get at the GUI (also had to remove the -v)

I tested the version from @That-Dude and it works under my VM of Big Sur 11.5.2. Catalina 10.15.3 fails.
