An attacker on the local system could make you overwrite one of your own files with a single byte. The problem exist when you use --compress or --tmux or --pipe or --cat or --fifo. The attacker must figure out the randomly chosen file name and create a symlink within a time window of 15 ms. * --shuf will generate all jobs, and shuffle them before running them.

This means that big environments (app. 100 KB) can be transferred. This change makes remote execution alpha quality. * --semaphoretimeout now takes a negative value. This means give up if the semaphore is not gotten within the timeout. * --halt -1 and -2 now means halt if a job succeeds (so the opposite of 1 and 2). * --no-keep-order will reverse --keep-order. * Bash's second fix of shellshock caused --env to break again when exporting functions. This has been fixed again. * A semibig refactoring of big functions. All non-trivial functions are now less than 100 lines. The refactoring makes this release beta quality. * A description of the design decisions for GNU Parallel can be found in 'man parallel_design'. * A bug fix in replacement strings caused rewrite of the replacement function. This makes use of replacement strings alpha quality. * GNU Parallel was cited in: SlideToolkit: An Assistive Toolset for the Histological Quantification of Whole Slide Images http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0110289 * GNU Parallel was cited in: Improving Energy and Performance with Spintronics Caches in Multicore Systems http://link.springer.com/chapter/10.1007/978-3-319-14313-2_24 * GNU Parallel was cited in: Parallel post-processing with MPI-Bash http://dl.acm.org/citation.cfm?id=2691137 * GNU Parallel was cited in: Distinguishing cause from effect using observational data: methods and benchmarks http://arxiv-web3.library.cornell.edu/pdf/1412.3773.pdf * GNU Parallel was cited in: Data Science at the Command Line http://cdn.oreillystatic.com/oreilly/booksamplers/9781491947852_sampler.pdf * GNU Parallel was cited in: Resolution of Genetic Map Expansion Caused by Excess Heterozygosity in Plant Recombinant Inbred Populations http://www.g3journal.org/content/4/10/1963.full.pdf * GNU Parallel was cited in: Bayesian Inference of Protein Structure from Chemical Shift Data https://peerj.com/preprints/692v1.pdf * GNU Parallel was cited in: Clonal interference and Mullerʼs ratchet in spatial habitats http://iopscience.iop.org/1478-3975/11/5/056003 * GNU Parallel was cited in: Web-scale content reuse detection ftp://info.isi.edu/isi-pubs/tr-692.pdf * GNU Parallel was cited in: Computação Verde na Camada de Aplicação https://linux.ime.usp.br/~tpaiva/mac0499/files/monografia.pdf * GNU Parallel was cited in: Frameshift alignment: statistics and post-genomic applications http://bioinformatics.oxfordjournals.org/content/30/24/3575.full.pdf+html * GNU Parallel was cited in: Towards Recommender Engineering Tools and Experiments for Identifying Recommender Differences http://elehack.net/research/thesis/mde-thesis.pdf * GNU Parallel was cited in: Speaker Environment Classification Using Rhythm Metrics in Levantine Arabic Dialect http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6923918 * GNU Parallel was cited in: A Formal Proof Of The Kepler Conjecture http://arxiv.org/pdf/1501.02155.pdf * GNU Parallel was cited in: Allocation Policy Analysis for Cache Coherence Protocols for STT-MRAM-based caches http://conservancy.umn.edu/bitstream/handle/11299/169362/Nandkar_umn_0130M_15551.pdf * GNU Parallel was cited in: Using Trusted Platform Module for securing virtual environment access in Cloud http://dar.aucegypt.edu:8080/bitstream/handle/10526/4237/Using%20Trusted%20Platform%20Module%20for%20Securing%20Virtual%20Environment%20Access%20in%20Cloud.pdf * GNU Parallel was cited in: Weakly Supervised Learning for Compositional Sentiment Recognition http://computerlinguist.org/static/downloads/ma-thesis/Master_Thesis-Michael_Haas-Weakly_Supervised_Learning_for_Compositional_Sentiment_Recognition.pdf * GNU Parallel was cited in: Agility and Performance in Elastic Distributed Storage http://dl.acm.org/citation.cfm?id=2668129 * GNU Parallel was used (unfortunately without citation) in: Large Scale Author Name Disambiguation in Digital Libraries http://semanticommunity.info/@api/deki/files/31523/P227_3546.pdf * GNU Parallel is used in BEDOPS: https://media.readthedocs.org/pdf/bedops/v2p5p0/bedops.pdf * Job ad asking for GNU Parallel skills: http://www.aplitrak.com/?adid=dXMzMTYxMjQuMzg0MTkuMTU1MEBtYW5wb3dlcmZveG5hLmFwbGl0cmFrLmNvbQ#sthash.kYCIhhty.KcoT6HnJ.dpbs * GNU Parallel: Open Source For You (OSFY) magazine, October 2013 edition http://www.shakthimaan.com/posts/2014/11/27/gnu-parallel/news.html * Multithreaded Encryption and Compression http://www.krazyworks.com/multithreaded-encryption-and-compression/ * GNU Parallel on OSX and Linux https://darknightelf.wordpress.com/2015/01/01/gnu-parallel-on-osx/ * How to build gnu parallel from source on Ubuntu PC? http://blog.ovidiuparvu.com/build-gnu-parallel-source-ubuntu-pc/ * GNU parallel for openaddr-process-one https://nelsonslog.wordpress.com/2015/01/09/gnu-parallel-for-openaddr-process-one/ * From SRA Project to FastQ http://danielecook.com/sra-project-fastq/ * Software Development Tooling http://www.computer.org/csdl/mags/so/2014/06/mso2014060021.pdf * コマンドを並列に実行するGNU parallelがとても便利 http://bicycle1885.hatenablog.com/entry/2014/08/10/143612 * Bug fixes and man page updates. 20141122 * Remote systems can be divided into hostgroups (e.g. web and db) by prepending '@groupname/' to the sshlogin. Multiple groups can be given by separating groups with '+'. E.g. @web/www1 @web+db/www2 @db/mariadb * Remote execution can be restricted to servers that are part of one or more groups by '@groupname' as an sshlogin. Multiple groups can be given by separating groups with '+'. E.g. -S @web or -S @db+web * With --hostgroup you can restrict arguments to certain hostgroups by appending '@groupname' to the argument. Multiple groups can be given by separating groups with '+'. E.g. my_web_arg@web db-or-web-arg@db+web db-only-arg@db Thanks to Michel Courtine for developing a prototype for this. * GNU Parallel was cited in: HTSeq-Hadoop: Extending HTSeq for Massively Parallel Sequencing Data Analysis using Hadoop http://essenceofescience.se/wp-content/uploads/2014/11/Siretskiy.pdf * GNU Parallel was cited in: SlideToolkit: An Assistive Toolset for the Histological Quantification of Whole Slide Images http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0110289#close * GNU Parallel was cited in: Exploring a multiprocessor design space to analyze the impact of using STT-RAM in the memory hierarchy http://conservancy.umn.edu/bitstream/handle/11299/167286/Borse_umn_0130M_15431.pdf * Command-Line OCR with Tesseract on Mac OS X https://ryanfb.github.io/etc/2014/11/13/command_line_ocr_on_mac_os_x.html * Bug fixes and man page updates. 20141022 * --env was changed to deal with Bash's new way of exporting a function. * GNU Parallel was cited in: Exclusion of cosmic rays in protoplanetary disks.

So if GNU Parallel is started from tcsh it will use tcsh as its shell even if the login $SHELL is different. For remote jobs the login $SHELL will be used. * The whole current environment in bash can be copied by using a shell wrapper function (Search manual for env_parallel). * --plus adds the replacement strings {+/} {+.} {+..} {+...} {..} {...} {/..} {/...}. The idea being that '+foo' matches the opposite of 'foo' and {} = {+/}/{/} = {.}.{+.} = {+/}/{/.}.{+.} = {..}.{+..} = {+/}/{/..}.{+..} = {...}.{+...} = {+/}/{/...}.{+...} * GNU Parallel now deals correctly with the combination rsync-3.1.X-client and rsync-2.5.7-server * GNU Parallel was cited in: A Web Service for Scholarly Big Data Information Extraction http://patshih.ist.psu.edu/publications/Williams-CiteSeerExtractor-ICWS14.pdf * Comparison of the speed of different GNU Parallel versions: http://lists.gnu.org/archive/html/parallel/2014-08/msg00030.html * GNU Parallel was covered in the webcast 2014-08-20: Data Science at the Command Line http://www.oreilly.com/pub/e/3115 * Distributed processing with GNU parallel http://kazjote.eu/2014/08/11/distributed-processing-with-gnu-parallel * A Peek into GNU Parallel http://blog.dataweave.in/post/94238943763/a-peek-into-gnu-parallel * Сборка GNU parallel для CentOS/RHEL http://www.stableit.ru/2014/07/gnu-parallel-centosrhel.html * Bug fixes and man page updates. 20140722 * {= perl expression =} can be used as replacement string. The expression should modify $_. E.g. {= s/\.gz$// =} to remove .gz from the string. This makes replacement strings extremely flexible. * Positional perl expressions (similar to {2}) are given as {=2 perl expression=} where 2 is the position. * One small backwards incompatibility: {1}_{2} will replace {2} with the empty string if there is only one argument. Previously {2} would have been left untouched. * Replacement strings can be defined using --rpl.

For each remote host: check that login through ssh works. If not: do not use this host. Currently you can not put --filter-hosts in a profile, $PARALLEL, /etc/parallel/config or similar. This is because GNU Parallel uses GNU Parallel to compute this, so you will get an infinite loop. This will likely be fixed in a later release. * --pipe now uses fork() instead of busy wait.

This will cause -l to mean --load, and the argument separator will be -- instead of ::: * --gnu will force GNU Parallel to behave like GNU Parallel even if --tollef is set. * Site wide config file: /etc/parallel/config This should solve the issue with some packagers renaming GNU Parallel to gparallel to avoid the naming conflict. By putting --tollef in the site wide config file you can deinstall Tollef's parallel and install GNU Parallel instead without any change for users or scripts. This is useful for packagers that currently rename GNU Parallel or simply do not distribute GNU Parallel because the command name conflicts with Tollef's parallel. * -L 0 -n 0, and -N 0 implemented. They will read one argument, but insert 0 arguments on the command line. Useful if you just want to run the same command with the same arguments a number of times. * GNU Parallel is now in Fink.

Each block is piped to a program for processing. The piping and the programs will be run in parallel. Useful if the data you want to process is data for a program and not arguments. * --blocksize sets the blocksize in bytes for --pipe. The blocksize is approximate. It can deviate as much as the size of one record. Default is 1M. * --recstart sets the string matching the start of a record. Default is "". * --recend sets the string matching the end of a record. Default is '\n'. To specify none use --recend "". If both --recstart and --recend are set, the end of a record must be followed immediately by a start of a record. This is useful if either recend or recstart can occur in the middle of a record. * --remove-rec-sep removes the string matched by --recstart and --recend. * --regexp will make GNU Parallel treat --recstart and --recend as regular expressions. * --output-as-files will put the output of the programs into files and instead of giving the output GNU Parallel will output the name of these files. * -N if used with --pipe sets the number of records to read. * New video showing --pipe at http://www.youtube.com/watch?v=1ntxT-47VPA * GNU Parallel was presented at FOSDEM. * Article in USENIX Magazine ;login: (print) http://www.usenix.org/publications/login/2011-02/ * GNU Parallel is now on ohloh.net. Thanks to Wim Muskee. https://www.ohloh.net/p/gnu-parallel * Advanced recursive example. Thanks to Ruarí Ødegaard. http://my.opera.com/ruario/blog/2011/01/24/editing-debian-packages-more-fun-with-gnu * Small example on using GNU Parallel through 0install (German). http://forum.ubuntuusers.de/topic/gnu-parallel-mit-zero-install-kurzinfo-kein-wi/ * Bug fixes and man page updates. 20110122 * --joblog makes a simple log of completed jobs. * -X now spreads arguments between job slots when reaching last argument. Use -j1 to avoid this. * People on the email list have voted -j+0 to be the new default instead of -j9. * First review in Polish. Thanks to Patryk Krawaczyński. http://nfsec.pl/root/2458 * Review in Spanish (in print). https://www.linux-magazine.es/issue/67/moreinfo.html * Review in English.

Thanks to Ruarí Ødegaard http://my.opera.com/ruario/blog/2011/01/18/fun-with-gnu-parallel * Use case for memcache. http://www.dctrwatson.com/2010/12/how-to-dump-memcache-keyvalue-pairs-fast/ * Bug fixes and man page updates. 20101222 * GNU niceload is now part of GNU Parallel. GNU niceload slows down a program if the load average is above a certain limit. * Implemented --tmpdir to buffer standard output and standard error in a different place. * Implemented --load to wait until the load is below a limit before starting another job on that computer. * Implemented --nice set the niceness of jobs running both locally and remotely. * Implemented --dry-run to print the job without running it. * Implemented --tty as the old default of assigning a tty to the first job causes problems. * Review with focus on clusters. Thanks to Taylor Gillespie http://www.unixpronews.com/unixpronews-49-20101019GNUParallelSpeedUpProcessingWithMulticoresClusters.html * Review with focus on protein similarity. http://kevinformatics.tumblr.com/post/2142473893/cluster-like-computing-using-gnu-parallel * Review in Spanish. http://gr3p.com/2010/12/gnu-parallel-acelera-tus-scripts-en-linux * Quite a few bug fixes and man page updates. 20101202 * Implemented {/} for the input line with the path removed (basename). * Implemented {/.} for the input line with extension and path removed (basename). * Output from --progress is now sent to standard error instead of standard output. * --eta was broken and counted down from 0. Now fixed. * Standard output and standard error are flushed after every job so if standard output does not end with a newline it will still be grouped with the rest of standard output. * --command, -c, --file, and -f are now removed as options. They were never used in practice. * GetOptionsFromArray rewritten to work with old Perl libraries. * The file COPYING now contains the GNU General Public License 3 * Major rewrite to make the code more object oriented and easier to maintain in the future. 20101113 * Using -j myfile the number of jobs can be changed while GNU Parallel is running simply by changing the content of myfile. * Implemented --profile to use different .parallel/config for different situations. * Ugly newlines in $PARALLEL and .parallel/config are no longer needed. Instead you have to use \ in front of special shell characters. * --workdir puts the files transferred to remote machines in a specified directory. * $PARALLEL_PID is set to the process id of GNU Parallel. * $PARALLEL_SEQ is set to the sequence number of the job. * -v now only shows the command to run. Use -v -v to show the ssh/rsync wrapping. * Slow spawning error is now only a warning. * If stdin is a tty and input is read from stdin you now get a warning. * GNU sql: \n and \x0a in arguments is replaced with newline. * Patch for Debian package and spelling mistakes. Thanks to Rogério Brito * Mac OS X Homebrew package. Thanks to Jonathan Palardy * FreeBSD port. Thanks to Chris Howey * Pardus package. Thanks to Fethican Coşkuner * First review in Chinese.

Tyler Croy : http://unethicalblogger.com/posts/2010/11/gnuparallel_changed_my_life * 5000 views of the intro video: http://www.youtube.com/watch?v=OpaiGYxkSuQ * As usual a bunch of bugfixes and more usage examples in the man page. * GNU Parallel was presented at FSCONS 2010-11-07: http://www.fscons.org/fs/gnu-parallel Hopefully the video will be online soon. 20100922 * See GNU Parallel live at FSCONS 2010-11-07: http://www.fscons.org/fs/gnu-parallel * Untested Debian and xUbuntu packages available through OpenSUSE build service: https://build.opensuse.org/package/show?package=parallel&project=home%3Atange * Using --retries a job will be retried on another computer if it fails. This is useful if some jobs fail for no apparent reason (such as network failure). * BSD xargs -o (open /dev/tty) is now default for the job running in foreground. Useful for interactive commands like: ls | parallel -Xuj1 vi * GNU sql now supports SQLite. * Renamed .dburl.aliases to .sql/aliases and /etc/sql/aliases. * GNU sql now support --list-tables * Alias for DBURL can contain '?query' part with %-quoting. 20100906 * Using --shebang GNU Parallel can be used as the parser for a script. E.g: #!/usr/bin/parallel --shebang traceroute (followed by lines of hosts) * First community generated bugfixes * Alt Linux package of GNU Parallel. Thanks to Michael Shigorin * Sunfreeware package of GNU Parallel. Thanks to Steven M. Christensen * Untested CentOS, Fedora, Mandriva, RedHat, and SUSE packages available through OpenSUSE build service: https://build.opensuse.org/package/show?package=parallel&project=home%3Atange * Review of GNU Parallel. Thanks to Andrew McFague amcfague at wgen dot net http://www.andrew-mcfague.com/linux/utilities-linux/ commands-every-serious-nix-user-should-know/#parallel * First 1000 views of the intro video * sql - a small script to access sql bases from the command line which is a handy companion to parallel --colsep 20100822 * Counting semaphore functionality: start a job in the background. If N jobs are already running, wait for one to complete. Examples: sem 'sleep 2; echo foo'; sem 'sleep 1; echo bar'; sem --wait sem -j2 'sleep 2; echo foo'; sem -j2 'sleep 1; echo bar'; sem --wait * With --colsep a table can be used as input. Example: cat tab_sep_table | parallel --colsep '\t' echo col1 {1} col2 {2} * --trim can remove white space around arguments. * --sshloginfile '..' means use ~/.parallel/sshloginfile * Zero install package. Thanks to Tim Cuthbertson * OpenSUSE package. Thanks to Markus Ammer * NixOS package. Thanks to Ludovic Courtès * Web review http://oentend.blogspot.com/2010/08/gnu-parallel.html Thanks to Pavel Nuzhdin * Web review http://psung.blogspot.com/2010/08/gnu-parallel.html Thanks to Phil Sung 20100722 * Arguments can now be given on the command line. Example: parallel bzip2 ::: *.txt * xapply like functionality. Example: parallel diff {1} {2} :::: filelist1 filelist2 parallel diff {1} {2} ">"{1.}-{2.}.diff :::: filelist1 filelist2 * Arch Linux package. Thanks to Peter Simons * Mandriva package. Thanks to Sandro Cazzaniga * -L -l -n -s now implies -X unless -m is set 20100620 * New video showing the new options. http://www.youtube.com/watch?v=OpaiGYxkSuQ or at http://tinyogg.com/watch/TORaR/ and http://tinyogg.com/watch/hfxKj/ * 100% options complete with xargs. All options for xargs can now be used in GNU Parallel - even the more exotic. * --basefile for transferring basedata. When running jobs on remote computers --basefile will transfer files before the first jobs is run. It can be used to transfer data that remains the same for each job such as scripts or lookup tables. * --progress shows progress. To see how many jobs is running on each server use --progress. It can be turned on even after GNU Parallel is started. * --eta shows estimated time left in seconds. * --halt-on-error stops if an error occurs. GNU Parallel will default to run all jobs - even if some of them fail. With --halt-on-error GNU Parallel can ignore errors, wait for the currently running jobs to finish, or stop immediately when an error occurs. 20100601 * GNU Parallel now has support for running jobs on remote machines * Intro video http://www.youtube.com/watch?v=LlXDtd_pRaY http://openvideo.dailymotion.com/video/xdmqwz_gnu-parallel-script-processing-and_tech 20100424 * GNU Parallel is now official GNU software
