Hey list… again
i’ve been checking the descriptions and examples of:
http://code.ettus.com/redmine/ettus/projects/public/wiki/Latency#To-Do
and everything looks pretty clear to me now, however i tried to make my
own
plots according to the instructions on the above page, at first
everything
looks fine and ./run_test.py gives me no trouble despite the fact that
im
not sure when to stop the test (they say after 5 successful delays how
do i
know when that happened?) im attaching to exit of this first instruction
hoping to be good.
The problem its then im trying to plot the results by typing "find .
-name
“latency*.txt” | ./graph.py 'cause i get the next error:
gflopa@gflopa-desktop:~/Downloads/latency-001$ find . -name
“latency*.txt”
| ./graph.py
