Searching and filtering output
You can filter CLI output from show commands and at the --More-- prompt. You can search for
individual characters, strings, or construct complex regular expressions to filter the output.
Searching and filtering output from show commands
You can filter output from show commands to display lines containing a specified string, lines that
do not contain a specified string, or output starting with a line containing a specified string. 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. Refer to
“Using special characters
in regular expressions” on page 12 for information on special characters used with regular
expressions.
