What's the best way to get the path of the executable during runtime?

Question

If my go program can be executed in different ways (cron, monit, etc..), what's the most reliable way to get the directory that contains the executable, during runtime?

In python, this would be the variable:

os.path.realpath(__file__)

Answer 1

It's probably the same as in C, in other words, there isn't a portable fool-proof method. See How do I find the location of the executable in C?
