File permissions within a snap

[Jenny Murphy]

Hi,
 Unfortunately, either inside or outside quotes it is still blank.

Do you have a link to that hello world example you mentioned.

The previous reply (from yesterday) mentioned the use of interfaces, maybe
this would be cleaner than messing around with scripts and environment
variables?
I am using snapcraft 1.1.0, are interfaces available to use in that version?
