Basic --filter-hosts is now working in git version. parallel --filter-hosts -S server-a -S nonexistant -S existant-but-down --onall hostname\;echo ::: a b
This will remove nonexistant and existant-but-down from the list of servers and only run commands on server-a. Currently you can NOT put --filter-hosts in a profile, $PARALLEL, /etc/parallel/config or similar. This is because GNU Parallel uses GNU Parallel to compute this, so you will get an infinite loop.
