NEWS

• Noteworthy changes in release 1.8 (2022-07-23) [stable]

• • Changes in Behavior

  Schedule -f/–full combined with non-linewise operations for deprecation.

  In a future release, -f/–full will only be usable with operations where

  it makes sense. For now, we print a warning to stderr when -f/–full is

  used with non-linewise operations, and such usage will no longer be

  supported.

  The bin operation now uses more intuitive bins. Previously, a command

  such as `datamash bin 1 <<< -0` would output -100; and -100 did not fall

  in its own bin. We now require all bins to take the form `[nx,(n+1)x)`

  with integer n and bin width x. We discard the sign on -0 and gate such

  inputs into the [0,x) bin.

  Operations taking more than one argument now provide more complete output

  with –header-out. Previously, an operation such as `pcov x:y` would

  produce an output header like `pcov(y)`, discarding the `x`. The new

  behavior will output header `pcov(x,y)`.

  datamash(1) no longer ignores –output-delimiter with the rmdup operation.

• • New Features

  New datamash option –sort-cmd argument to specify the program used

  by the -s option to sort input, plus enhancements to the security and

  portability of building sort command lines.

  New datamash option -c/–collapse-delimiter=X argument uses character

  X instead of comma between values in collapse and unique lists.

  New datamash operations: mean square (ms) and root mean square (rms).

  Decorate now supports sorting IP addresses of both versions 4 and 6

  together. IPv4 addresses are logically converted to IPv6 addresses,

  either as IPv4-Mapped (ipv6v4map) or IPv4-Compatible (ipv6v4comp)

  addresses.

  Add two command aliases:

    ‘echo’ may now be used instead of ‘cut’.

    ‘uniq’ may now be used instead of ‘unique’.

• • Improvements

  Updated the bash completion script to reflect recent additions.

• • Bug Fixes

  Datamash now passes the -z/–zero-terminated flag to the sort(1) child

  process when used with “–sort –zero-terminated”. Additionally,

  if the system’s sort(1) does not support -z, datamash reports the error

  and exits. Previously it would omit the “-z” when running sort(1),

  resulting in incorrect results.

  Documentation fixes and spelling corrections.

  Incorrect format in a decorate(1) error breaking compilation on some

  systems.

  datamash(1), decorate(1): Fix some minor memory leaks.

  datamash(1) no longer crashes when the unique or countunique operations

  are used with input data containing NUL bytes.  The problem was reported

  in https://lists.gnu.org/archive/html/bug-datamash/2020-11/msg00001.html

  by Catalin Patulea.

  datamash(1) no longer crashes when crosstab with –header-in is called

  by field name instead of index. I.e. `datamash –header-in ct x,y` now

  works as expected.
