Description Ed Maste freebsd_committer 2014-10-16 01:28:07 UTC
\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% /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
