Hello,
I have installed parallel , When I am testing the installation, I am getting the following error
parallel -j0 ping -nc 3 ::: foss.org.my gnu.org freenetproject.org


the error is :

:~/parallel/parallel-20150222$ parallel -j0 ping -nc 3 ::: foss.org.my gnu.org freenetproject.org
parallel: Error: -g has been retired. Use --group.
parallel: Error: -B has been retired. Use --bf.
