Run the command at this niceness. For simple commands you can just add
B<nice> in front of the command. But if the command consists of more
sub commands (Like: ls|wc) then prepending B<nice> will not always
work. B<--nice> will make sure all sub commands are niced - even on
remote servers.
Run the command at this niceness.
By default GNU B<parallel> will run jobs at the same nice level as GNU
B<parallel> is started - both on the local machine and remote servers,
so you are unlikely to ever use this option.
Setting B<--nice> will override this nice level. If the nice level is
smaller than the current nice level, it will only affect remote jobs
(e.g. current level is 10 and B<--nice 5> will cause local jobs to be
run at level 10, but remote jobs run at nice level 5).

B<interlace> is built for network analysis to run network tools in parallel.
B<interface> does not buffer output, so output from different jobs mixes.
The overhead for each target is O(n*n), so with 1000 targets it
becomes very slow with an overhead in the order of 500ms/target.
Using B<prips> most of the examples from
https://github.com/codingo/Interlace can be run with GNU B<parallel>:
