In text editors like EditPad Pro or GNU Emacs, and regex tools like PowerGREP, the caret and dollar always match at the start and end of each line. This makes sense because those applications are designed to work with entire files, rather than short strings. Your first regex really means: [\^a]b # match a literal '^' or 'a', followed by a 'b' Your second regex: ^b # match start of line followed by a 'b' What you really want for your first regex is: ^b|ab # match start of line followed by a 'b', # OR # an 'a' followed by a 'b'
