slackbuilds_ponce/system/xjobs

xjobs reads job descriptions line by line and executes them in
parallel. It limits the number of parallel executing jobs and starts
new jobs when jobs finish. Therefore, it combines the arguments from
every input line with the utility and arguments given on the command
line. If no utility is given as an argument to xjobs, then the first
argument on every job line will be used as utility. To execute utility
xjobs searches the directories given in the PATH environment variable
and uses the first file found in these directories.

xjobs is most useful on multiprocessor machines when one needs to
execute several time consuming commands that could possibly be run in
parallel. With xjobs this can be achieved easily, and it is possible
to limit the load of the machine to a useful value. It works similar
to xargs, but starts several processes simultaneously and gives only
one line of arguments to each utility call.
