A metacharacter is a character that has a special meaning to a computer program, such as a shell interpreter or a regular expression (regex) engine. In POSIX extended regular expressions, there are 14 metacharacters that must be escaped (preceded by a backslash (\)) in order to drop their special meaning and be treated literally inside an expression: opening and closing square brackets ([ and ]); backslash (\); caret (^); dollar sign ($); period/full stop/dot (.); vertical bar/pipe symbol (|); question mark (?); asterisk (*); plus and minus signs (+ and -); opening and closing curly brackets/braces ({ and }); and opening and closing parentheses (( and )). For example, to match the arithmetic expression (1+1)*3=6 with a regex, the correct regex is \(1\+1\)\*3=6; otherwise, the parentheses, plus sign, and asterisk will have special meanings. (Wikipedia).
