This is a progress: until now, you did not manage to get ffmpeg to
understand that you want the concat filter. This is now working, the quoting
is correct. You now have to resolve the inconsistency of the inputs you put
to concat and the number you set as options.

n = 3, v = 1, a = 0 means 3×(1+0) = 3 inputs, and you gave 6. Please read
the doc for the meaning of the options.

ffmpeg gets the single quotes as part of the argument, it should not. The
single quote is here in the example for the shell, not for ffmpeg.
