Searching and filtering output
1
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. For example, to filter on output
containing an asterisk, enter the asterisk portion of the regular expression as “\*”.

Allowable characters for LAG names
When creating a LAG name, you can use spaces in a file or subdirectory name if you enclose the
name in double quotes. For example, to specify a subdirectory name that contains spaces, enter a
string such as the following: “a long subdirectory name”. The maximum length for a string is 64
characters.
^ A caret (when not used within brackets) matches on the beginning of an input string.
For example, the following regular expression matches output that begins with “deg”:
^deg
$ A dollar sign matches on the end of an input string.
For example, the following regular expression matches output that ends with “deg”:
deg$
_ An underscore matches on one or more of the following:
•
, (comma)
•
{ (left curly brace)
•
} (right curly brace)
•
( (left parenthesis)
•
) (right parenthesis)
•
The beginning of the input string
•
The end of the input string
•
A blank space
For example, the following regular expression matches on “100” but not on “1002”, “2100”, and
so on.
[ ] 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)?)
