$scriptdir isn't evaluated in run.sh

[PhaedrusTheGreek]

For me, the following:

template_file_path="@${scriptdir}/elasticsearch/elasticsearch-template-5x.json"

results in: @/elasticsearch/elasticsearch-template-5x.json

├ $ ./test.sh
++ readlink -f ./test.sh
readlink: illegal option -- f
usage: readlink [-n] [file ...]

s/readlink/stat works for me
