Here's your answer.
>Traditional regex is what came before it
No, that's "ancient regex".
- trashb 7mo ago> No, that's "ancient regex". wouldn't the "ancient regex" be the ed "g/re/p" version? -E, --extended-regexp Interpret PATTERNS as extended regular expressions (EREs, see below). -G, --basic-regexp Interpret PATTERNS as basic regular expressions (BREs, see below). This is the default. -P, --perl-regexp Interpret I<PATTERNS> as Perl-compatible regular expressions (PCREs). This option is experimental when combined with the -z (--null-data) option, and grep -P may warn of unimplemented features. From the manpage it seems my grep make distinction between "Extended" "Basic" and "Perl" regexes.
