I was trying to read up on it and just based off of the manual it seems not to make sense if I’m not using --silent alongside it, but I found this one article stating otherwise: https://nrogap.medium.com/show-error-response-for-curl-64666cd64330

I can’t figure out if it’s just AI slop or badly researched since it doesn’t even show a real URL to test the commands against.

Manual entry: 

       -S, --show-error
              When used with  -s,  --silent,  it
              makes  curl  show an error message
              if it fails.

              This option is global and does not
              need  to be specified for each use
              of -:, --next.

              Providing -S, --show-error  multi‐
              ple  times  has  no  extra effect.
              Disable it again  with  --no-show-
              error.

              Example:
               curl --show-error --silent https://
example.com

              See also --no-progress-meter.

    They’re just examples of things you could pipe curl into, but no not really. If the download fails you end up with an incomplete file in your tmpfs anyway, and have to retry. Another use I have is curl | mysql to restore a database backup.

    If the server supports resuming, I guess that can be better than the pipe, but that still needs temporary disk space, and downloads rarely fail. You can’t corrupt downloads over HTTPS either as the encryption layer would notice it and kill the connection, so it’s safe to assume if it downloaded in full, it’s correct.

    With downloads being IO bound these days, it’s nice to not have to read it all back and write the extracted files to disk afterwards. Only writes the final files once.

    That’s far from the weirdest thing I’ve done with pipes though, I’ve installed Windows 11 on a friend’s PC across the ocean with a curl | zstd | pv | dd, and it worked. We tried like 5 different USBs and different ISOs and I gave up, I just installed it in a VM and shipped the image.
