> I have the bin directory of Flink in my $PATH variable, so I can just do 
> "flink run" on the command line for executing stuff.
> However, I have multiple Flink versions locally and its hard to find out 
> which installation the bash is picking in the end.
> adding a simple "version" command will resolve that issue and I consider it 
> helpful in general.
