GNU Parallel 20160722 ('Brexit') has been released. It is available for download at: http://ftp.gnu.org/gnu/parallel/

Haiku of the month:

Pipes are fast and good.
Use them in your programs, too.
Use GNU Parallel
-- Ole Tange

New in this release:

* env_parallel is now ready for wider testing. It is still beta quality.

* env_parallel is heavily modified for all shells and testing has been increased.

* Selectively choosing what to export using --env now works for env_parallel (bash, csh, fish, ksh, pdksh, tcsh, zsh).

* --round-robin now gives more work to a job that processes faster instead of same amount to all jobs.

* --pipepart works on block devices on GNU/Linux.

= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be 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. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

If you use xargs and tee 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 can even replace nested loops.

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.

You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/

You can install GNU Parallel in just 10 seconds with: (wget -O - pi.dk/3 || curl pi.dk/3/) | bash

= About GNU SQL =

GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and
port number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

When using GNU SQL for a publication please cite:

= About GNU Niceload =

GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run
for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
