Thanks for the input. You are absolutely correct. I tested my script but only with index.txt empty. I just tried it with something in index.txt and it still detected it as empty because, as you point out -s is for the file test while -z is for the string test. So in my case it is checking if the string "/var/ipfire/certs/index.txt" is not empty, which of course it will never be empty.

Duuuh.

I just tried it with -z replaced by -s and that properly detects if the file is empty or not.


Hi Michael,

Could you please change the ! -z to ! -s in my last patch or should I send out a v2 patch?

Regards,

Adolf.
