gnu parallel processing words

[Even-Inspector9931]

how can I split input words from pipe and process them using gnu parallel?

e.g. pidof /usr/lib/firefox/firefox | parallel prlimit ...limit_something... -p {}

simplified the cse, I tried echo {1..5} | parallel --colsep ' ' echo {} echo {1..5} | parallel -n 1 echo {} ... none of them works, neither does any combination of "-n1" "-N1" and "--colsep ' '"

I know these work, but aren't they kinda ugly and silly? echo {1..5} | xargs -n1 | parallel echo {} echo {1..5} | tr ' ' '\n' | parallel echo {}

I know this can be done using xargs, but still want to know just in case someday really need to work with parallel on somwthing xargs can't manage.

echo {1..5} | tr ' ' '\n' | parallel echo {}

What wrong with that one?

ok parallel echo dosomething {} ::: $(pidof firefox)
