Every file name associated with a "real file" is a hardlink. (Device files and symlinks aren't quite "real files". I don't think the names in directories for these items quite count as "hardlinks". I don't know how I'd classify named pipes. I bet they are closer to "hardlinks" than not. :) > 2. What are the circumstances where symbolic links do not work? I love > symbolic links but some utilities such as "tftp" doesn't follow the link. Symbolic links are entirely up the application in question. They can decide for themselves whether they wish to use lstat(2) or stat(2), or whether they should pass O_NOFOLLOW to open(2), etc. tar(1) can switch between behaviors with -h; GNU ls support -d, -H, -L. BSD ls supports -d and -l. etc. In short -- no easy answer. -- "It seems the power has been robbed from the founding fathers and is now firmly in the hand of the funding fathers." -- Rik van Riel
