Let's say that I am currently in /a/b/c/d/e/, and I want to make symbolic link with a file f.txt in that directory. If I do ln -s f.txt /etc/, the file /etc/f.txt will not point to the file, because it just points f.txt, not /a/b/c/d/e/f.txt. I have tried ln -s ./f.txt /etc/, but that created a link literally to ./f.txt.
So, other than typing the full path myself, like /a/b/c/d/e/f.txt, is there any shortcut to tell ln that I want to use the absolute path of the file in the current directory?
