I suggest you try

sh -x ./bin/logstash –f logstash.conf

to see which command is generating that error.

It took me a while to understand this. You can see that at the end of the java exec is

org.logstash.Logstash $'\226f' logstash.conf

Your problem is that where you have '-f logstash.conf' on your command line, you have used an en-dash (octal \226 in Windows CP1251) and not a hyphen (octal \55, decimal 45). That is, you have –f instead of -f.

Thank you so much! It worked :slight_smile: You are a genius!
