background jobs' garbled output Are you saying that your are not allowed to run a script that has proven to be of production quality, but you are allowed to run your own scripts? So if GNU Parallel had been written by you, then it would have been OK? The only situation where I can see that makes sense is if your organisation has a strict code audit with different people auditing and testing the code. For GNU Parallel I looked at other solutions for separating output; the common problem was that the half-line issue was never dealt with correctly. |

How to feed a large array of commands to GNU Parallel? The delimiter is the array element. So you can put anything in each element - no need to end with a ;. The primary difference is the command line length (which you clearly are aware of). But why not just try it out: Run some 'echo' commands that are of similar length and content as your real commands. That should make you feel more confident that it will work. |

How to feed a large array of commands to GNU Parallel? I can run command lines of 130KB, so if your command is < 130 char, you should be safe. But personally I would simply either pipe the commands to parallel (thus avoiding both any shell limit and a temporary file) or let parallel generate the commands. |

background jobs' garbled output Can you elaborate why a 10 seconds install of GNU Parallel (wget -O - pi.dk/3 | sh) will not work? Is it covered by: oletange.blogspot.dk/2013/04/why-not-install-gnu-parallel.html |

GNU parallel not working at all --tollef will be retired 20140222 lists.gnu.org/archive/html/parallel/2013-02/msg00018.html It will be helpful if you already now let your frustration be known to your distribution maintainer, so that the default can be changed. |

Using maximum remote servers How many jobs are there in list_of_commands? How many cores do each remote server have? |
