Character Meaning Remarks
$
Ending sign, the string before
it appears only at the end of a
line.
Regular expression "user$”
matches a string ends with
“user”, not “userA”.
.
Full stop, a wildcard used in
place of any character,
including blank
None
*
Asterisk, used to match a
subexpression zero or
multiple times before it
zo* can map to “z” and “zoo”.
+
Addition, used to match a
subexpression one or
multiple times before it
zo+ can map to “zo” and “zoo”,
but not “z”.
-
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).
[ ]
Selects one character from
the group.
For example, [1-36A] can
match only one character
among 1, 2, 3, 6, and A.
( )
A group of characters. It is
usually used with “+” or “*”.
For example, (123A) means a
string “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.
