Translations:GNU Parallel/13/en

If some of the subcommands failed (i.e. they produced a non-zero exit code) and you think that you have eliminated the source of the error, you can re-run the failed ones, using --resume-failed, e.g.

[name@server ~]$ ls *.txt | parallel --resume-failed --joblog gzip.log gzip {}

Note that this will also start subjobs that were not considered before.
