https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287396 Bug ID: 287396 Summary: grep(1): BSD grep \w matches differently from GNU grep Product: Base System Version: 14.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: elfham+freebsd@gmail.com It seems that the \w character class in BSD grep matches differently compared to GNU grep. Specifically, GNU grep's \w matches the underscore (_), whereas BSD grep does not. Is this behavior intentional? admin@freebsd14:~ $ cat /etc/os-release NAME=FreeBSD VERSION="14.3-RELEASE" VERSION_ID="14.3" ID=freebsd ANSI_COLOR="0;31" PRETTY_NAME="FreeBSD 14.3-RELEASE" CPE_NAME="cpe:/o:freebsd:freebsd:14.3" HOME_URL="https://FreeBSD.org/" BUG_REPORT_URL="https://bugs.FreeBSD.org/" admin@freebsd14:~ $ echo $LANG C.UTF-8 admin@freebsd14:~ $ grep --version grep (BSD grep, GNU compatible) 2.6.0-FreeBSD admin@freebsd14:~ $ echo a_ | grep -o '\w*' a admin@freebsd14:~ $ ggrep --version ggrep (GNU grep) 3.11 Copyright (C) 2023 Free Software Foundation, Inc.
