On OS X 10.9.5 my bash shell has the following environment variable set:
__CHECKFIX1436934=1
What is the purpose of this value? I am surprised there is no record of anybody asking this before.
It comes from launch services, specifically this binary
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/LaunchServices
and that environment variable seems to be inherited by many processes, as you can see with ps -Efax
1436934 looks like the number of digits in recent Apple "radar" bug numbers, so perhaps it refers to some value used internally for testing.
__CHECKFIX1436934=1in my ENV too. I note that the few search results that I find for this include it as part of programmers asking for help and listing their ENV related to the Go language, Python, SublimeText or Brew. I have all of these installed. – Lee Joramo Oct 8 '14 at 17:04
