Bug ID: 194397
Summary: Base GNU grep does not handle \s in extended regex
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: ema...@freebsd.org
\s should match whitespace but does not:
FreeBSD 11.0-CURRENT from Sep. 21
joule% echo 'a b' | /usr/bin/grep -E '^a\sb'
joule%
joule% /usr/bin/grep --version
grep (GNU grep) 2.5.1-FreeBSD
GNU grep package works:
joule% echo 'a b' | /usr/local/bin/grep -E '^a\sb'
a b
joule% /usr/local/bin/grep --version
/usr/local/bin/grep (GNU grep) 2.20
BSD grep works:
echo 'a b' | /usr/bin/bsdgrep -E '^a\sb'
joule% /usr/bin/bsdgrep --version
bsdgrep (BSD grep) 2.5.1-FreeBSD
BSD grep and base GNU grep both link against /usr/lib/libgnuregex.so.5
