How to run OMNeT++ project from Ubuntu terminal

I am using OMNeT++ 5.5.1 installed in Ubuntu 19.04 and it is working fine in IDE environment.

But, I need to run an INET project from Ubuntu terminal. Can anyone suggest me what command to write in terminal if:

I want to run, for example, INET showcase examples ( wireless/sensornetwork/omnetpp.ini)?
how to see the list of configurations in omnetpp.ini?
and how to choose one specific config and run it?

Thank you

Solution

To run a simulation from command line do the following:

Go to directory of the example you want to start, e.g.:
```
cd showcases/wireless/sensornetwork
```
To see available config names in omnetpp.ini type:
```
opp_run -a
```

To run selected config (e.g. LMac) with GUI type the following command:

opp_run -m -u Qtenv -n ../../../src:../..:../../../tutorials:../../../showcases -l ../../../src/INET  omnetpp.ini  -c LMac

To see all runs for selected config type:
```
opp_run -s -c LMac omnetpp.ini -q runs
```

To start one selected run (e.g. 5) from config (e.g. LMac) without GUI type the following command:

opp_run -m -u Cmdenv -n ../../../src:../..:../../../tutorials:../../../showcases -l ../../../src/INET  omnetpp.ini  -c LMac -r 5

To start all runs in selected config (e.g. LMac) type the following command:

opp_run -m -u Cmdenv -n ../../../src:../..:../../../tutorials:../../../showcases -l ../../../src/INET  omnetpp.ini  -c LMac

The main options for opp_run:

-u Qtenv selects graphical view of a simulation (for command environment use -u Cmdenv)
-n indicates directories of NED files
-l selects library (here: libINET.so)
