To display lines that do not contain a specified search string (similar to the exclude option for show commands)
press the minus sign key ( - ) at the --More-- prompt and then enter the search string.
The filtered results are displayed:
As with the commands for filtering output from show commands, the search string is a regular expression
consisting of a single character or string of characters. You can use special characters to construct complex
regular expressions. See the next section for information on special characters used with regular expressions.
Using Special Characters in Regular Expressions
You use a regular expression to specify a single character or multiple characters as a search string. In addition,
you can include special characters that influence the way the software matches the output against the search
string. These special characters are listed in the following table.
Table 2.3: Special Characters for Regular Expressions
Character Operation
. The period matches on any single character, including a blank space.
For example, the following regular expression matches “aaz”, “abz”, “acz”, and so on, but
not just “az”:
a.z
* The asterisk matches on zero or more sequential instances of a pattern.
For example, the following regular expression matches output that contains the string
“abc”, followed by zero or more Xs:
abcX*
+ The plus sign matches on one or more sequential instances of a pattern.
For example, the following regular expression matches output that contains "de", followed
by a sequence of “g”s, such as “deg”, “degg”, “deggg”, and so on:
deg+
