The regular expression is a string of 1 to 256 characters, case sensitive, and space allowed. It supports
multiple mapping rules:
z begin : Displays the configuration beginning with the specified regular expression.
z exclude : Displays the configuration excluding the specified regular expression.
z include : Displays the configuration including the specified regular expression.
The regular expression also supports special characters as shown in Table 60-5 .
Table 60-5 Special characters in a regular expression
Character Meaning Remarks
^
Starting sign, the string following it appears only
at the beginning of a line. Regular expression “^user” matches a
string begins with “user”, not “Auser”.
$
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.
