problem with shebang

[ogmueller]

some syntax in the script is incompatible with /bin/sh, e.g. ${} or $()

shebang has to be something like /bin/bash

--- a/blcheck
+++ b/blcheck
@@ -1,4 +1,4 @@
-#!/bin/sh
+#!/bin/bash

Should we change the shebang or the code? :)

[ogmueller]

Personally I would recommend to change the shebang, because bash should be available on most/all distributions and the code is more "modern" and cleaner.

I didn't see this but I made a PR: #15
