Your first point makes it impossible for me to present anything because 
this list doesn't (AFAIK) allow attachments. I can only present a 
copy-pasted example.

Your second point would assume that I'm using a non-standard shebang. I 
use #!/bin/sh unless I need something that is only available in bash 
(can't recall a case of that). Moreover, the consensus seems to be that 
if there was an error on the shebang line, the default shell would be used.

The smallest complete script then is

report=”/root/clamscan-report”
echo $report

but as I explained, that works on one server but not the other. Hence my 
question wasn't "what's wrong with this line" but rather "how do I 
change the behaviour". I'm not expecting anyone else to be able to 
reproduce the problem because I can't even do it except on the one server.

And to do that, I didn't even need the shebang line. I could enter the 
line at the command prompt then echo it and see the same result. Since 
it wasn't the shebang line, and didn't even require being in a script, 
why should I have included the shebang line?
