GNU Parallel 20150522 ('Nepal') released [stable]

Item posted by Ole Tange <tange> on Thu 21 May 2015 10:48:26 PM UTC.

GNU Parallel 20150522 ('Nepal') has been released. It is available for download at: http://ftp.gnu.org/gnu/parallel/

No new functionality was introduced so this is a good candidate for a stable release.

Haiku of the month:

  Many jobs to run.
  Idle cores is not your thing.
  Use GNU Parallel.
      -- Ole Tange

New in this release:

• Security: The security issue for --sshlogin + --fifo/--cat has been fixed. Thereby all issues with http://lists.gnu.org/archive/html/parallel/2015-04/msg00045.html have been fixed.

• Security: After further security analysis the issue fixed in 20150422 also fixed the problem for --tmux.

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

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.

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.
