Oops ... still not quite time for a victory lap ...
Some time ago, we worked out that I could run several awk commands like this
concurrently in separate terminal windows:
> time sudo nmap -sS -p3389 -T4 --host-timeout 300 --min-hostgroup 25 -iL
Input-IPv4s.txt > nMap-IPv4s-to-HNs.txt
and even:
> time sudo nmap -sS -p3389 -T4 --host-timeout 300 --min-hostgroup 25 -iL
Input-CIDRs.txt > nMap-IPv4s-to-HNs.txt
Those never collided with each other ...
Now I was planning to run concurrently several commands of the form:
time tr -sc 0-9\\n ' ' < Input01.txt | awk '{ k = 0; for (i = 0; k < 4 && ++i
