Subject: GNU Parallel 20210222 ('AngSangSuKyi<<>>') released <<[stable]>>

GNU Parallel 20210222 ('') <<[stable]>> has been released. It is available for download at: http://ftpmirror.gnu.org/parallel/

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

Please help spreading GNU Parallel by making a testimonial video like Juan Sierra Pons: http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4

It does not have to be as detailed as Juan's. It is perfectly fine if you just say your name, and what field you are using GNU Parallel for.

Quote of the month:

  GNU Parallel is a priceless timesaver
    -- June "Wakalix" @TWakalix@twitter

  
New in this release:

* --filter only run jobs where the filter is true. The filter can contain replacement strings and Perl code such as: '{1} < {2}+1'

* --template takes a text file as a template with replacement strings. Then it replaces the replacement strings and saves it under a new filename.

* --plus implements {0%} {0#} replacement string for zero padded slot and sequence.

* Warn that you probably mean -d '\r\n' if the first 3 values end in \r\n (DOS newline).

* {= perlexpression =} must return the same value, if run twice on the same input.

* Man pages available as .rst-format.

* Bug fixes and man page updates.

If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.


= 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.

For example you can run this to convert all jpeg files into png and gif files and have a progress bar:

  parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif

Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:

  find . -name '*.jpg' |
    parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200

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 || lynx -source pi.dk/3 || curl pi.dk/3/ || \
       fetch -o - http://pi.dk/3 ) > install.sh
    $ sha1sum install.sh | grep 3374ec53bacb199b245af2dda86df6c9

= 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.
