only at the beginning of a line.

1 to 9 (inclusive); “a-h” means from a to h
(inclusive).

A range of characters, Matches
any character in the specified
range.
For example, [16A] can match a string
containing any character among 1, 6,
and A; [1-36A] can match a string
containing any character among 1, 2, 3,
6, and A (with - being a hyphen).
“]” can be matched only when it is put at
the beginning of [ ] if it is used as a
common character in [ ], for example
[ ]
string ]. There is no such limit on “[”.
( )
A character group. It is usually
used with “+” or “*”.
For example, (123A) means a character
group “123A”; “408(12)+” can match
40812 or 408121212. But it cannot
match 408.
