  It's not a data migration party until GNU Parallel is involved...

  I get a weird sense of satisfaction every single time I see the
  lovely logo of #GNU Parallel (plus, what an underrated piece of
  great software!)

  I have gotten a *ton* of mileage out of jq, awk, and GNU parallel,
  even at multi-GB sizes.
    -- Eric Wolak @ericthewolak@twitter 

GNU parallel, which works a little bit like xargs, but has a much more friendly way of handling files with spaces and automatically parallelises calls. This tool has saved me a great deal of coding because it makes it so easy to write a program which does just one part of a task and then run it in parallel with load balancing and a nice progress bar. I cannot recommend this tool enough.

  GNU parallel all the way!
    -- David Manouchehri @DaveManouchehri@twitter

  I found GNU Parallel and it's awesome.
    -- Teddy Choi @TeddyJChoi@twitter

  Well anyway, It was blazingly fast and astonished by performance. Guess I'll never use xargs.
    -- (Not) Akaming @_Akamig@twitter

  Yeah, GNU parallel is a beast when used accordingly.
    -- @lsde@twitter

  GNU Parallel is awesome

  My new favourite command line tool is GNU Parallel. After knowing it for a while I just recently came back to it for a refactor of a script and now I've changed like 4 different huge scripts into tiny parallel scripts that do their job literally 3 to 10 times faster and just [mind blown]

  I love so much @GnuParallel to parallelize my SQL requests on @PostgreSQL

  GNU parallel really changed how I do a lot of data processing stuff
    -- Brendan Dolan-Gavitt @moyix@twitter
  
  Parallel is a life send, what an awesome piece of software.

  It's really powerful for smallish data processing scripts

  GNU parallel is a seriously powerful flexible and tool.
    -- Greg Hurrell @wincent@twitter

  [socat is] top3 on my "crazy and powerful" list (the other two being
  gnu parallel and emacs).
    -- Peter Kjellström @nsccap@twitter

  GNU/Parallel umm... tempting.
    -- k-leb k @dcatdemon@twitter

  Ain't that a dirty hack ;-)

  Not sure if it counts as an "alt" tool but GNU parallel really took my shell scripting game to the next level.
    -- @alinajaf@twitter

  Gnu parallel is also awesome, fwiw.
    -- Rogan Dawes @RoganDawes@twitter

  With multicore systems everywhere GNU Parallel is a must have tool.

  Who needs spark when GNU Parallel exists
    -- MatthijsB @MatthijsBrs@twitter

  GNU Parallel: dead simple process-level parallelization of ad hoc
  tasks. Write for a chunk, let gnu manage the splitting, permutations
  and pool concurrency.
    -- Nick Ursa @nickursa@twitter


  I wish more command line software had example pages as robust as GNU Parallel
    -- Lucidbeaming @lucidbeaming

  GNU parallel is straight up incredible.
    -- Ben Johnson @biobenkj@twtter

  GNU parallel has helped me kill a Hadoop cluster before.
    -- Travis Campbell @hcoyote@twitter

  Parallel is the BEST command.
    -- Nick @NickInfoSec@twitter

  [L]earning about parallel was amazing for me, it gives us many beautiful solutions.
     -- SergioAraujo@stackoverflow

  I've said it before: The command line program GNU Parallel is a godsend.
    -- Jo Chr. Oterhals @oterhals

  IMHO, SQLite and GNU Parallel are among the world's great software.

  It is, beyond absolutely any doubt whatsoever, the single most
  important tool I use in making me a productive bioinformatician.

It is SUPER easy to speed up jobs from the command line w/ GNU parallel.
  -- B3n @B3njaminHimes@twitter

I want to make a shout-out for @GnuParallel, it's a work of beauty and power
  -- Cristian Consonni @CristianCantoro

Amazingly useful script!

Y'all need some GNU parallel in your lives
-- ChaKu @ChaiLovesChai@twitter


There are so many things to love about GNU parallel. You could honestly teach a whole parallel computing course with it and never have to leave it for a real language.
-- Aubrey Bailey @DNAvinci@twitter


With GNU Parallel you sure can!
I like getting things done

--Kyle Lady @kylelady@twitter

Ok! GNU Parallel is one of the best things out there. Almost as good as vanilla ice cream.

Such an easy way to get huge speed-ups with my simple bash/Perl/Python
programs -- parallelize them!

Alias and vars
export them more easily
With env_parallel

You know what?
GNU Parallel is cool.
Concurrency, but in the Unix-philosophy style,
without the Enterprise wankeriness.
