It Xlimits the number of parallel executing jobs and starts new jobs when jobs Xfinish. Therefore, it combines the arguments from every input line with the Xutility and arguments given on the command line. If no utility is given as an Xargument to xjobs, then the first argument on every job line will be used as Xutility. To execute utility xjobs searches the directories given in the PATH Xenvironment variable and uses the first file found in these directories. X Xxjobs is most useful on multi-processor/core machines when one needs to execute Xseveral time consuming command several that could possibly be run in parallel. XWith xjobs this can be achieved easily, and it is possible to limit the load of Xthe machine to a useful value. It works similar to xargs, but starts several Xprocesses simultaneously and gives only one line of arguments to each utility Xcall.
