Description Volodymyr Kostyrko 2018-11-11 20:06:11 UTC 
The following code should pass both strings along, but passes none:

printf 'xxx\nyyy\n' | bsdgrep '\(xxx\|yyy\)'

Alternations ("|") are ERE feature (see 9.4.7 in http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html), so you need to run it as:

$ printf "xxx\nyyy\n" | bsdgrep -E 'xxx|yyy'
xxx
yyy

Thanks for clarification, was under impression that it should be working as it works on GNU grep. Sorry.
