Here is the GNU grep home page:

    http://gnu.org/s/grep/



For a summary of changes and contributors, see:

  http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v3.9

or run this command from a git-cloned grep directory:

  git shortlog v3.8..v3.9



Here are the compressed sources:

  https://ftp.gnu.org/gnu/grep/grep-3.9.tar.gz   (2.7MB)

Here are the GPG detached signatures:

Here are the SHA1 and SHA256 checksums:

  q80RQJ7iPUyvNf60IuU7ushnAUz+7TE7tfSIrKFwtZk=  grep-3.9.tar.xz



Verify the base64 SHA256 checksum with cksum -a sha256 --check

from coreutils-9.2 or OpenBSD's cksum since 2007.



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 grep-3.9.tar.gz.sig



The signature should match the fingerprint of the following key:



  pub   rsa4096/0x7FD9FCCB000BEEEE 2010-06-14 [SCEA]

        Key fingerprint = 155D 3FC5 00C8 3448 6D1E  EA67 7FD9 FCCB 000B EEEE

  uid                   [ unknown] Jim Meyering 

  uid                   [ unknown] Jim Meyering 

  uid                   [ unknown] Jim Meyering 



If that command fails because you don't have the required public key,

or that public key has expired, try the following commands to retrieve

or refresh it, and then rerun the 'gpg --verify' command.



  gpg --locate-external-key jim@meyering.net



  gpg --recv-keys 7FD9FCCB000BEEEE



  wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=grep&download=1' | gpg --import -



As a last resort to find the key, you can try the official GNU

keyring:



  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg

  gpg --keyring gnu-keyring.gpg --verify grep-3.9.tar.gz.sig



This release was bootstrapped with the following tools:

  Autoconf 2.72a.65-d081

  Automake 1.16i

  Gnulib v0.1-5861-g2ba7c75ed1

* Noteworthy changes in release 3.9 (2023-03-05) [stable]



** Bug fixes



  With -P, some non-ASCII UTF8 characters were not recognized as

  word-constituent due to our omission of the PCRE2_UCP flag. E.g.,

  given f(){ echo Perú|LC_ALL=en_US.UTF-8 grep -Po "$1"; } and

  this command, echo $(f 'r\w'):$(f '.\b'), before it would print ":r".

  After the fix, it prints the correct results: "rú:ú".



  When given multiple patterns the last of which has a back-reference,

  grep no longer sometimes mistakenly matches lines in some cases.

  [Bug#36148#13 introduced in grep 3.4]
