GNU Parallel Bug Reports GNU Parallel 20140422 (' 세월호') released

[Ole Tange]

GNU Parallel 20140422 ('세월호') has been released. It is available for
download at: http://ftp.gnu.org/gnu/parallel/

New in this release:

* --pipepart is a highly efficient alternative to --pipe if the input
is a real file and not a pipe.

* If using --cat or --fifo with --pipe the {} in the command will be
replaced with the name of a physical file and a fifo respectively
containing the block from --pipe. Useful for commands that cannot read
from standard input (stdin).

* --controlmaster has gotten an overhaul and is no longer experimental.

* --env is now copied when determining CPUs on remote system. Useful
for copying $PATH if parallel is not in the normal path.

* --results now chops the argument if the argument is longer than the
allowed path length.

* Build now survives if pod2* are not installed.

* The git repository now contains tags of releases.

* GNU Parallel was cited in: Proactive System for Digital Forensic

= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one
or more computers. A job is 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

Walk through the tutorial (man parallel_tutorial). Your commandline
will love you for it.

= 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.

Databases Using DBURLs, ;login: The USENIX Magazine, April 2011:29-32.


= 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.
