Happy Hacking! - Assaf Gordon ================================================================== Here are the compressed sources and a GPG detached signature[*]: https://ftp.gnu.org/gnu/datamash/datamash-1.5.tar.gz https://ftp.gnu.org/gnu/datamash/datamash-1.5.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/datamash/datamash-1.5.tar.gz https://ftpmirror.gnu.org/datamash/datamash-1.5.tar.gz.sig [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify datamash-1.5.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 0A11B61D3657B901 and rerun the 'gpg --verify' command. ================================================================== The checksums of the archive are: $ sha1sum datamash-1.5.tar.gz ba35ed8130005a8a2bb0869f0e67b67378b7d1ce datamash-1.5.tar.gz $ sha256sum datamash-1.5.tar.gz 226249d5fe54024f96404798778f45963a3041714229d4225cd5d9acdaba21ad datamash-1.5.tar.gz $ sha512sum datamash-1.5.tar.gz 9f7bff0858a7519ef8efc30ef39c3e99f17e81ed847f1edce6ff28e1191d52fbc173baa5d21d6852effbbf2af800604920d92d412f45519700a9b5809da0e8fa datamash-1.5.tar.gz $ b2sum datamash-1.5.tar.gz 3b377d5886ac7de0066c30ffa7a8923230b928514274be10b213d1a0631709b1c940a4da07709d0cb67a6719f5da9b9f045b8a5bb519370b64a677d20547aa17 datamash-1.5.tar.gz ================================================================== NEWS ** New Features Datamash now accepts backslash-escaped characters in field names. This allows working with named fields containing dash/mins,colons,commas or field names starting with digits (Note the interplay between backslash and shell quoting). The following are equivalent, and sum an input field named 'FOO-BAR': datamash -H sum FOO\\-BAR < input.txt datamash -H sum 'FOO\-BAR' < input.txt datamash -H sum "FOO\\-BAR" < input.txt New operations: dirname, basename These behave just like dirname(1) and basename(1): $ echo /home/foo/bar.txt | datamash dirname 1 basename 1 /home/foo bar.txt New operations: extname, barename 'extname' extract the extension of the file name. 'barename' (not to be confused with 'basename') extract the basename without the extension. Example: $ echo /home/foo/bar.tar.gz | datamash barename 1 extame 1 bar tar.gz New operation: getnum This operation extracts a number from a string. 'getnum' accepts an optional single letter option: getnum:n - natural numbers (positive integers, including zero) getnum:i - integers getnum:d - decimal point numbers getnum:p - positive decimal point numbers (this is the default) getnum:h - hex numbers getnum:o - octal numbers Examples: $ echo foo-42.0-bar | datamash getnum 1 42.0 $ echo foo-42.0-bar | datamash getnum:n 1 42 $ echo foo-42.0-bar | datamash getnum:i 1 -42 $ echo foo-42.0-bar | datamash getnum:d 1 -42.0 New operation: cut Similar to cut(1), it copies the input field to the output as-is. The advantage over cut(1) is that combined with datamash's other features, input fields can be specified by name instead of column number, and output fields can be re-ordered and duplicated. Example: $ printf "a b c\n1 X 6\n" | datamash -W -H cut c,a,c cut(c) cut(a) cut(c) 6 1 6 ** Bug fixes Datamash now correctly calculates mode/antimode for negative values. In version 1.4 and earlier, the following produced incorrect results: $ echo -1 | datamash-1.4 mode 1 1.844674407371e+19 -- If you have a working or partly working program that you'd like to offer to the GNU project as a GNU package, see https://www.gnu.org/help/evaluation.html.
