^ Match the beginning of the line if the word begins with ^ $ Match the end of the line if the word ends with $ Please escape them to search metacharacters-ed strings. For example, to search 'abc$' or '^abc', we should doubly escape these metacharacters like 'abc\\$' and '\\^abc' respectively. We could specify 'abc$$' and '^^abc' to get the effects; "searching 'abc$' at the end" or "searching '^abc' at the beginning". In other words, '^' and '$' will be escaped when they have *NOT* been placed at the beginning nor ending respectively. Signed-off-by: Takeshi Banse <email@example.com>
