JMeter unknown arg ?t

I'm trying to run JMeter in non-gui mode (from the command line).

I've seen in a number of places, including the official docs, that this following command will do what I want:

jmeter -n –t test.jmx -l testresults.jtl

However, I get an illegal argument exception for the "t" argument. See below for my console output:

Below is the output saved to jmeter.log:

Solution

  • So the issue was how I was getting the command into the command line.

    When I copied and pasted my command, it was copied from a webpage, into notepad, and then into the command line. I wrongly assumed notepad would encode the correct character.

    Just a bit confusing as the -n worked but not -t. Silly error!
