Table 9. Special characters for regular expressions (continued)
Character Operation
[ ]
Square brackets enclose a range of single-character patterns.
For example, the following regular expression matches output that contains
“1”, “2”, “3”, “4”, or “5”:
[1-5]
You can use the following expression symbols within the brackets. These
symbols are allowed only inside the brackets.
^ - The caret matches on any characters except the ones in the brackets. For
example, the following regular expression matches output that does not
contain “1”, “2”, “3”, “4”, or “5”:
[^1-5]
- The hyphen separates the beginning and ending of a range of characters.
A match occurs if any of the characters within the range is present. See the
example above.
|
A vertical bar separates two alternative values or sets of values. The output
can match one or the other value.
For example, the following regular expression matches output that contains
either “abc” or “defg”:
abc|defg
( )
Parentheses allow you to create complex expressions.
For example, the following complex expression matches on “abc”, “abcabc”,
or “defg”, but not on “abcdefgdefg”:
((abc)+)|((defg)?)
If you want to filter for a special character instead of using the special character as
described in the table above, enter “
\ ” (backslash) in front of the character.
