OMNET++: Run simulation in command line

Question

In my omnetpp.ini file, I have these lines describing cmdenv:

[General]
cmdenv-express-mode = false
cmdenv-output-file = log.txt
cmdenv-autoflush = true
cmdenv-status-frequency = 10000000s

So my outputs are redirected to a log file. To run my simulation I access to run -> run configurations -> user interface command line

Now, I need to run the omnetpp.ini file using a server so I need to run the .ini file in command line and not using the previous steps mentioned. I followed these two solutions that I found in the mailing list but they do not work:

1) ./run -u Cmdenv -f omnetpp.ini

2) opp_run -u Cmdenv -f omnetpp.ini

This is what display:

HP-ProBook-650-G2:~/WorkspaceThese/Veins-4a2/examples/veins$ opp_run -u     Cmdenv -f omnetpp.ini

Cmdenv: redirecting output to file `/home/yosra/WorkspaceThese/Veins-        4a2/examples/veins/log.txt'...

End.

Can someone help me to fix this issue please?

I do not understand your problem, can you edit your question again? — Julian Heinovski
I need to run the omnetpp.ini file using the linux terminal and not the interface of Omnet++. I tried the two commands but they don't work. — Joe
What do you mean by "they do not work"? What does the error message display? Did you compile the code beforehand? Usually you also need to specify a config which should be executed '-c <config>'. — Julian Heinovski

Can you update your question and put this message and the content of the log file which is mentioned there as well? — Julian Heinovski

If you are able to run your simulation in Cmdenv mode from Eclipse, you may see what Eclipse uses to run the simulation. To do it add the Console ( Window | Show View | Other | Console) and start your simulation in Cmdenv mode. In the console you will see something like this:

Starting...

$ cd /opt/omnetpp/omnetpp-4.6/samples/tictoc/simulations
$ ../src/tictoc -r 0 -u Cmdenv -c General -n ../src;. omnetpp.ini

Here are the commands you are looking for.
