GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.

--Shebang-Wickel macht es nun möglich, Skripte zu parallelisieren, indem man "parallel" in der Shebang-Zeile (die erste #! Linie in Skripts).

--Verzögerung fügt eine Verzögerung nach dem starten jeden Job (nützlich, um Raceconditions und donnernde Herde Probleme zu vermeiden).

--Ergebnisse jetzt verwendet "/" als Trennzeichen nicht Registerkarte, und schafft damit die Unterverzeichnisse.

OpenBSD CPU-Erkennung wird jetzt durchgeführt.

Niceload--Sensor kann negative Zahlen bedeuten eine niedrigere Zahl, was bedeutet, dass die Grenze niedriger ist.

Niceload--Prg unterbricht ein benanntes Programm, das bereits ausgeführt wird.

Niceload hält mehrere--pid Prozess-Ids, die bereits ausgeführt werden.
--shebang-wrap now makes it possible to parallelize scripts by putting
"parallel" in the shebang
line (the first #! line in scripts).

--delay adds a delay after starting each job

(useful to avoid raceconditions and thundering herd problems).

--results now uses "/" as a separator instead of TAB, and thus creates

OpenBSD CPU detection is now performed.

niceload --sensor allows negative numbers to signify a lower number,
meaning the limit is lower.

niceload --prg suspends a named program which is already running.

niceload multiple --pid suspends process ids which are already running.
