What Others Think

Do we really need the -n1 option for parallel? I did a little experiment as below: diff <(find . -type f | parallel --no-notice -n1 -j200% md5sum ::: | awk 'x[$1]++ { print $2 " :::"}' | sed 's/^/Dupe: /g'|sed 's,Dupe,\x1B[31m&\x1B[0m,') <(find . -type f | parallel --no-notice -j200% md5sum ::: | awk 'x[$1]++ { print $2 " :::"}' | sed 's/^/Dupe: /g'|sed 's,Dupe,\x1B[31m&\x1B[0m,') # nothing here So seems both the commands give the same result. I am suppressing the notice printing with the --no-notice option to parallel.
