Remarks
For example, (string)\1 repeats string, and a
matching string must contain stringstring.
(string1)(string2)\2 repeats string2, and a
matching string must contain string1string2string2.
(string1)(string2)\1\2 repeats string1 and string2
respectively, and a matching string must contain
string1string2string1string2.
For example, [^16A] means to match a string
containing any character except 1, 6 or A, and the
matching string can also contain 1, 6 or A, but
cannot contain these three characters only. For
example, [^16A] matches "abc" and "m16", but
not 1, 16, or 16A.
For example, "\<do" matches word "domain" and
string "doa".
For example, "do\>" matches word "undo" and
string "abcdo".
For example, "\ba" matches "-a" with "-" being
character1, and "a" being character2, but it does
not match "2a" or "ba".
For example, "\Bt" matches "t" in "install", but not
"t" in "big top".
For example, "v\w" matches "vlan", with "v" being
character1, and "l" being character2. v\w also
matches "service", with "i" being character2.
For example, "\Wa" matches "-a", with "-" being
character1, and "a" being character2, but does not
match "2a" or "ba".
For example, "\\" matches a string containing "\",
"\^" matches a string containing "^", and "\\b"
matches a string containing "\b".
