hmm... I've noticed the latest screenfetch-dev using better solution to show ProductionVesion and BuildVersion via

$ sw_vers --productVersion
13.3.1
$ sw_vers --buildVersion
22E772610a

However, the version was cut off. here are pull request: #767

The syntax of the sw_vers command is not quite the same as yours ：

$ sw_vers --productVersion
Usage: sw_vers [-productName|-productVersion|-buildVersion]
$ sw_vers -productVersion 
12.6.8
$ sw_vers -buildVersion  
21G725

I had to modify the script to fit my MacOS.

Below way is more safe:

$ sw_vers | grep -i productversion | awk '{print $2}'
12.6.8
