GNU parallel show jobs remaining

Question

I guess this question/problem can be tackled by the satisfaction of one (or more) of the below problems

1) How do I show jobs remaining? 2) How do I pretty the output of --eta

1) I've checked the man page, and I am presently using $PARALLEL_SEQ in my function, but how can I get the jobs remaining? Parallel is help me to compile about 800 files, and I'd would like to know my jobs remaining.

2) Alternatively, is there a better (nicer) way to output --eta? My output looks really messy. I would only like to see a single ETA.

The parallel flags I am using: --no-notice --keep-order --group

Example of output:

819: Compiling form: USER_Q                         ok

Answer 1

You will need to redirect the output of your jobs to have --eta look nice:

seq 10 | parallel --eta 'echo foo; sleep .{}'  >/dev/null

That will also show number of jobs left. You may also find --bar usable:

seq 10 | parallel --bar 'echo foo; sleep .{}'  >/dev/null

Or a more advanced example:

seq 1000 |
  parallel -j30 --bar '(echo {};sleep 0.3)' \
  2> >(perl -pe 'BEGIN{$/="\r";$|=1};s/\r/\n/g' |
       zenity --progress --auto-kill) | wc
