perl.

Though the equivalent of readlink -f is not straightforward.

perl -le 'print readlink(shift)' -- "$file"

The point is to have something very lightweight, and very
least-common-denominator. I think that ls+sed would be lighter than
running perl, plus perl might not be there in really bad setups...

Maybe ``realpath'':

|$ apt-cache show realpath
|Package: realpath
|Priority: optional
|Section: utils
|Installed-Size: 72
|Maintainer: Robert Luberda
|Architecture: amd64
|Source: dwww

|Description: Return the canonicalized absolute pathname
| The package contains a small utility realpath, which converts each
| pathname argument to an absolute pathname, which has no components
| that are symbolic links or the special . or .. directory entries.
| .
| This utility provides mostly the same functionality as `/bin/readlink -f'
| in the coreutils package.
