Hi @knatsakis ,

I think we are having problems in our check system, months ago I wrote a PR using some conditions like yours and I had to change due shellcheck results, today I saw that you used the same comparison that was rejected to me and when I ran the shellcheck in both files I got the expected error report:

Please, can you check why our shellcheck is not reporting correctly? No less important, can you run in your side and fix the list of errors displayed in the image?

Thank you!

Hi @thiagoftsm,

As per our discussion, let's proceed by ignoring the shellcheck errors and open a new ticket for the lack of shellcheck in travis.

All right, I already created a new issue with the errors reported here and on 7083.

Everything worked as expected during my tests with this PR on a Debian 9.11 and latest version of docker available in this distribution.
