If there is no match at all, the system does not modify the incomplete keyword and displays it again in the next line.

^string

Starting sign, string appears only at the beginning of a line.

For example, regular expression “^user” only matches a string beginning with “user”, not “Auser”.

string$

Ending sign, string appears only at the end of a line.

For example, regular expression "user$” only matches a string ending with “user”, not “userA”.

.

Full stop, a wildcard used in place of any character, including single character, special character and blank.

For example, “.l” can match “vlan” or “mpls”.

*

Asterisk, used to match a character or character group before it zero or multiple times.

For example, “zo*” can match “z” and “zoo”; (zo)* can match “zo” and “zozo”.

+

Addition, used to match a character or character group one or multiple times before it

For example, “zo+” can match “zo” and “zoo”, but not “z”.

|

Vertical bar, used to match the whole string on the left or right of it

For example, “def|int” can only match a character string containing “def” or “int”.

_

Underline. If it is at the beginning or the end of a regular expression, it equals ^ or $; in other cases, it equals comma, space, round bracket, or curly bracket.

For example, “a_b” can match “a b” or “a(b”; “_ab” can only match a line starting with “ab”; “ab_” can only match a line ending with “ab”.

-

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).

[ ]

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.

\index

Repeats a specified character group for once. A character group refers to the string in () before \. index refers to the sequence number (starting from 1 from left to right) of the character group before \: if only one character group appears before \, then index can only be 1; if n character groups appear before index, then index can be any integer from 1 to n.

For example, (string)\1 means to repeat string for once, and (string)\1 must match a string containing stringstring; (string1)(string2)\2 means to repeat string2 for once, and (string1)(string2)\2 must match a string containing string1string2string2; (string1)(string2)\1\2 means to repeat string1 for once first, and then repeat string2 for once, and (string1)(string2)\1\2 must match a string containing string1string2string1string2.

[^]

Used to match any character not in a specified range.

For example, [^16A] means to match a string containing any character except 1, 6 or A, and the string can also contain 1, 6 or A, but cannot contain these three characters only. For example, [^16A] can match “abc” and “m16”, but not 1, 16, or 16A.

\<string

Used to match a character string starting with string.

For example, “\<do” can match word “domain” or string “doa”.

string\>

Used to match a character string ending with string.

For example, “do\>” can match word “undo” or string “abcdo”.

\bcharacter2

Used to match character1character2. character1 can be any character except number, letter or underline, and \b equals [^A-Za-z0-9_].

For example, \ba can match -a, with - represents character1, and a represents character2; while \ba cannot match “2a” or “ba”.

\Bcharacter

It must match a string containing character, and there can no spaces before character.

For example, “\Bt” can match “t” in “install”, but not “t” in “big top”.

character1\w

Used to match character1character2. character2 must be a number, letter or underline, and \w equals [^A-Za-z0-9_].

For example, “v\w” can match “vlan”, with “v” being character1, and “l” being character2. v\w can also match “service”, with “i” being character2.

\W

Equals \b.

For example, “\Wa” can match “-a”, with “-” representing character1, and “a” representing character2; while “\ba” cannot match “2a” or “ba”.

\

Escape character. If single special characters listed in this table follow \, the specific meanings of the characters will be removed.

For example, “\\” can match a string containing “\”, “\^” can match a string containing “^”, and “\\b” can match a string containing “\b”.
