Hello,

with an old version of parallel, the `--nice` option sets the niceness of the process.

    $ parallel --version
    GNU parallel 20130922
    [...]

    $ parallel -vv --dry-run --nice 10 echo ::: hello
    \nice -n10 /bin/bash -c echo\ hello

However, with the version in Stretch, it does not work anymore.

    $ parallel --version
    GNU parallel 20161222
    [...]

    $ parallel -vv --dry-run --nice 10 echo ::: hello
    echo hello

Cheers

Charles

Hi Ole,

I was able to reproduce the issue below with the Debian packaged version
20210822.

Kind regards

      Andreas.

Testing with a `sleep 60` shows the nice level to be set correctly.
Just --dry-run doesn't show command prefixes any more.

(tested with the latest upstream as I looked at the source due to #915541)
