Split a Linux pipe

The command is tee and the syntax is:

cat ... | tee >(one) >(two)

For example, for same url, we want to request it with both curl and curl --user-agent 'Mobile' :

cat urls \
  | tee \
    >(parallel --load 8 -j 8 -q curl -H "Cache-Control:max-age=0" \
      -s -w %{url_effective}:%{http_code}:%{time_total}'\n' -o /dev/null) \
    >(parallel --load 8 -j 8 -q curl -H "Cache-Control:max-age=0" --user-agent "Mobile" \
      -s -w %{url_effective}:%{http_code}:%{time_total}'\n' -o /dev/null)
