oo -a npm-lb -e npr -p npm | parallel --tag --nonall -S - --basefile ./dev.sh ./dev.sh
I had a look at the code and it looks like there's a bit of a learning curve to get a patch going if its beyond the trivial.
tips? its a huge perl script

Getting the sshlogins from stdin is easy:
... | parallel --tag --nonall --slf - fixThings.sh
But it seems you have found a bug: --transfer does not work with
--(n)onall. Otherwise this ought to work (THIS DOES NOT WORK NOW):
... | parallel --tag --nonall -S - --transfer fixThings.sh :::
file1_to_transfer file2 3rd
--basefile works, though. So maybe you can use that as a work around.
myfunc() {
... | parallel --tag --nonall -S - --basefile "$1" fixThings.sh
}
export -f myfunc
parallel -j1 myfunc ::: file1_to_transfer file2 3rd
It is unclear to me whether it will be easy to get --transfer to work
with --nonall. Patch welcome.
