Bruno P. Kinoshita commented on JENA-1297:
------------------------------------------

I think the last time I had to write something like this, I used pushd/popd to 
go into that directory (symlink or not), then pwd -P to retrieve real folder, 
and used thst value.don't remember why didn't use readlink

On a side note, running shellcheck agaisnt all Jena shell scripts would be good 
too

> Code to set JENA_HOME in scripts doesn't work (links)

>             Project: Apache Jena
>          Issue Type: Bug
>          Components: Cmd line tools
>    Affects Versions: Jena 3.2.0
>         Environment: OS X 10.11.6 (15G1217). Java 1.8.0_92

> I'm trying the script bin/sparql, to me the code that deals with links when 
> setting JENA_HOME is unnecessary, it ends up setting '.' as the prefix for 
> lib/ ad triggering main class not found (when putting $JENA_HOME/bin in PATH).
> The same script works when I set JENA_HOME with the physical path of Jena, 
> not its symlink (which I don't like, because I prefer to upgrade by 
> symlinking the last version to 'jena' and not having to change anything else).
> I've tried a version of such script where I removed all if [ -L ... ]  and it 
> works perfectly well. In my opinion, the existing code (using dirname ... && 
> pwd) is enough to track the folder where the script is.
