This is + repeated for each argument. The default is to run all + the commands at the same time. + + + + + OPTIONS + + + + + + + Use to limit the number of jobs + that are run at the same time. + + + + + + + Avoid starting new jobs when + the system's load average is higher + than the specified limit. + + + + + + + Normally the command is passed the + argument at the end of its command line. With + this option, the first instance of "{}" in + the command is replaced with the argument. + + + + + + + + + EXAMPLE + + + + parallel -j 3 ufraw -o processed -- *.NEF + + + + This runs three ufraw processes at the same time until + all of the NEF files have been processed. + + + + + + EXIT STATUS + + + Its exit status is the combination of the exit statuses of each + command ran, ORed together. (Thus, if any one command + exists nonzero, parallel as a whole will exit nonzero.) + + + + -- cgit v1.2.3
