Version 20121022 ('Hanne Vilmann') of GNU Parallel
Release Notes: --results now structures output files so that they can be imported using Pandas (http://pandas.pydata.org/). This is useful when doing simulations to select output from some arguments. --env can be used to transfer environment variables through ssh to remote machines.
Other releases
Release Notes: The software can now be installed in 10 seconds by running wget -O - pi.dk/3 | sh. CPU detection was added for HURD, IRIX, SCO OpenServer, and HPUX. --ctrlc will send SIGINT to tasks running on remote computers and thus kill them. --load now uses 'ps' to find the number of running processes instead of 'uptime' and is much faster. CentOS 3.9 and FreeBSD 7 compatibility bugs were fixed. Some of these required quite extensive changes, making this release beta quality. --retries now works with --onall. The new --load computation now works on FreeBSD 7. --nice works under tcsh.
Release Notes: --resume works with --pipe. --resume-failed will go through --joblog, redo the failed jobs, and then continue like --resume. Negative positional arguments count from the end: {-1} means the last argument, {-2} the second to last. NetBSD CPU detection. --blocksize increases exponentially if it smaller than a full record. Processing n-line records (--pipe -L n) is now much faster. --tollef is obsoleted after discussion on the mailing list.
Release Notes: --sshdelay delays starting the next SSH by the specified number of seconds. The value can be less than 1 second.
Release Notes: --shebang-wrap now makes it possible to parallelize scripts by putting "parallel" in the shebang line (the first #! line in scripts). --delay adds a delay after starting each job (useful to avoid raceconditions and thundering herd problems). --results now uses "/" as a separator instead of TAB, and thus creates subdirectories. OpenBSD CPU detection is now performed. niceload --sensor allows negative numbers to signify a lower number, meaning the limit is lower. niceload --prg suspends a named program which is already running. niceload multiple --pid suspends process ids which are already running.
Release Notes: niceload --sensor makes it possible to use a program to control whether a program should be suspended.
