Replying to [comment:9 jdemeyer]:
> I attach a shell script which should be portable (however, I have not
yet tested this) and behaves like "readlink -f" if combined with `( cd
$dir && pwd )`. I guess this would solve all problems mentioned here. I
still have to think about the best way of using this from
`$SAGE_ROOT/sage`.
I'll suggest for a last time that you check out #6146. There is a script
there that is simpler, shorter, and has some testing. Portability is not
so easy... your script hangs on my first try on SunOS 5.10 (fulvia). Note
also that because we are assuming bash, we can portably use "pwd -P" as a
bash builtin.
If you can figure out a way to make "readlink -f" work (when available),
i.e. finish fixing #5852, then #6146 already gives a solution for systems
where "readlink -f" is not available.
