According to GNU paralle man: --bar Show progress as a progress bar. In the bar is shown: % of jobs completed, estimated seconds left, and number of jobs started. --eta Show the estimated number of seconds before finishing. This forces GNU parallel to read all jobs before starting to find the number of jobs. GNU parallel normally only reads the next job to run. Implies --progress. --progress Show progress of computations. List the computers involved in the task with number of CPU cores detected and the max number of jobs to run. After that show progress for each computer: number of running jobs, number of completed jobs, and percentage of all jobs done by this computer. The percentage will only be available after all jobs have been scheduled as GNU parallel only read the next job when ready to schedule it - this is to avoid wasting time and memory by reading everything at startup. By sending GNU parallel SIGUSR2 you can toggle turning on/off --progress on a running GNU parallel process. See also --eta. I have some troubles with send big sequence (by example 60000) to parallel to show job progression. For litlle sequence also but it's not a problem because it's a short time. I don't know if the fact i use remote computer have some bad effects on statistics. In live environment i push an input file (1 million entry) to parallel with option --eta, parallel seems frozen and the treatment progress very slowly. Default tratment it's done in 30 mn, but with --eta option 1h30 after is very far to be complete and give the impression it's need one day to be finish. I need to have a live indicator and for batch how many jobs are trated by each computers (local and remotes). Perhaps, it's me, i don't use well parallel with the right grammar. Below and some example to repoduce the problem.
