The first one is fine, the second one complains. Aren't these both backed by the same regex lib? Why the difference? Which standard should apps in base adhere to? I prefer the former as allowing empty subexpressions saves a ton of space on the command line by not requiring the enumeration of the expansion. ls | egrep '^.+\.foo(\.bar|)$' find -sE . -regex '^\./.+\.foo(\.bar|)$' -maxdepth 1 find: -regex: ^\./.+\.foo(\.bar|)$: empty (sub)expression
