ahh ok. I have not been aware of this = thing.
I tried like this:
% l
total 0
-rw------- 1 user user 0  19:23 18.05.2015  file
lrwxrwxrwx 1 user user 4  19:24 18.05.2015  lnk1 -> file
% sll lnk1
lrwxrwxrwx 1 user user 4 Mai 18 19:24 lnk1 -> file

Which gave me nothing more usefull over ls -l. But as i understand its purpose
is to do a $path lookup first, which in turn is neat.

I look into this. And also in updating its comment and usage hint.

Thanks!
