So, let's say I have an array with a list of URLs, and I want to use something such as GNU parallel to download the URLs in parallel. A command like this would do the trick.

parallel -u wget -qc --show-progress ::: "${URLs[@]}"

The only issue with this command is while the progress of the commands is shown (especially since -u shows the output as it happens rather than waiting) the output of the commands all go to the same line. This results in a scenario in which when one wget instance outputs it overwrites the progress of the previous wget output on the tty. So, I was wondering how to have each wget output on it's own line at the same time?

parallel --ll wget -qc --show-progress ::: "${URLs[@]}"

The --ll option is in alpha testing, but works in my test.

  • Thanks. I should mention that this didn't work when using parallel from Ubuntu's apt repository (on 22.04). I had to download it from the GNU website and compile it. Commented Apr 12, 2023 at 15:19
  • Exactly what was needed; works on Fedora 40. parallel --version - GNU parallel 20230822 uname -r - 6.8.11-300.fc40.x86_64 Commented Jun 29, 2024 at 2:55
