Yeah, that's annoying. It makes me want to use Perl sometimes. However, GNU grep does have a --perl-regexp (-P) option, so this would work, $ printf 'x\t'|grep -P '\t' x but it's not portable enough. Even among systems with recent GNU grep, some compile it out, e.g. Debian's grep says this: grep: Support for the -P option is not compiled into this --disable-perl-regexp binary
