What is the number between file permission and owner in ls -l command output?
I've been using Linux for years now and I'm embarrassed to say that until now I didn't notice that I have no idea what the second column of
ls -l means:
-r--r--r-- 1 roic develop1 roic 685 2012-10-11 14:15 API.h ^
In this example - 1. What does it stand for?
