How to get GNU Parallel report every file processed?

Question

I would like to keep track of GNU parallel in a simple log file and would like it to emit the name of each as it starts / ends (either or both are equally fine). It seems verbose is too verbose for this.

Answer 1

If you make a profile that does the logging:

echo 'echo {} >> my.log;' > ~/.parallel/log

Then you can do this:

parallel -J log seq {} ::: 1 2 3

But since the profile uses {} you need to mention {} explicitly.

THIS DOES NOT WORK:

parallel -J log seq ::: 1 2 3
