File.open(file, ‘a+’) won’t work when the file is not readable.
However, in a shell I can append a string using
echo string >> file
Am I forced to use exec + echo to append content, or is there a way to
append a string to a file using ruby code… without opening the file?

Use mode ‘a’ instead of ‘a+’ in File.open
That worked like a charm, thanks!

Just a quick thanks… this pointed me in the right direction for some
of the more advanced uses of ‘open’. It’ll come in handy. =)
