of a line.

Asterisk, the character to the left of the
asterisk should match zero or more
consecutive times.

and so on, but not zo.
+
Plus sign, the character to the left of the
plus sign should match one or more

Hyphen. It connects two values (the
smaller one before it and the bigger one
after it) to indicate a range together with

For example, 1-9 means numbers from 1
to 9 (inclusive); a-h means from a to h
(inclusive).
[ ]
Square brackets. Specifies a range of
characters, and matches any character
in the specified range.
For example, [1-36A] can match a
string containing any character among
1, 2, 3, 6, and A.
( )
Parenthesis. Specifies 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.
That is, 12 can appear continuously and
it must at least appear once.
