PATTERN MODIFIERS(开关)

i             Case-insensitive
m             Multiline   : allow the grep engine to match at  ^ and $ after and before at \r or \n.
s             Magic Dot   : allows . to match \r and \n
x             Free-spacing: ignore unescaped white space; allow inline comments in grep patterns.

(?imsx)       On
(?-imsx)      Off
(?i-msx)      Mixed
