GNU Parallel 20150109alpha released

Item posted by Ole Tange <tange> on Fri 09 Jan 2015 10:38:07 PM UTC.

GNU Parallel 20150109alpha has been released. It is available for download at:

To make remote execution send stderr to stderr a major change has been implemented in remote execution. If you use GNU Parallel for remote execution (--sshlogin) then please test this alpha release.

As always it passes the testsuite, so most functionality clearly works.

New in this release:

  • Remote jobs now send stderr (standard error) to stderr (standard error) instead of stdout (standard output).
  • Remote execution command is now packed using hex encoded bzip2. This means that big environments (app. 250 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).
  • 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.
  • Bug fixes and man page updates.

GNU Parallel - For people who live life in the parallel lane.
