@comfreak it works for me on macOS 12.6 too, but man readlink says that -f accepts format value. I'm confused

@SnoringFrog: I just tested readlink -f on the current macOS (12.6) and it works as intended. If the argument is a symlink, it will show the absolute path of the symlink target.

From readlink manpage (coreutils 8.32-1): "Note realpath(1) is the preferred command to use for canonicalization functionality". They are both from coreutils.

I think that OP did not ask for resolving symlinks. If that is true, then this is a faulty answer. An "absolute path" and "resolved symlinks" are two different things. For getting absolute paths without resolving symlinks, realpath -s can be be used.

@iconoclast Those options aren't available on OSX, and as per the BSD readlink manpage: only the target of the symbolic link is printed. If the given argument is not a symbolic link, readlink will print nothing and exit with an error, so readlink won't work for this purpose on OSX

hluk: -f option is also the one to use in OpenBSD

@Dalin: /usr/bin/readlink on Mavericks. Or did you mean those options are not found on OS X? It seems to be a stunted BSD version... :p

It seems to me that -m is the best option to use.

| Nov 16, 2010 at 0:15 | comment | added | catphive | This looks like the simplest to me, while also being portable. readlink is port of the gnu coreutils, so it will be installed on almost any linux distribution, except for some embedded ones. | |
