To display lines containing only a specified search string (similar to the include option for show
commands) press the plus sign key ( + ) at the --More-- prompt and then enter the search string.

The filtered results are displayed.

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.

.

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*
