Searching and filtering output at the --More-- prompt

The --More-- prompt displays when output extends beyond a single page. From this prompt, you can
press the Space bar to display the next page, the Return or Enter key to display the next line, or Ctrl
+C or Q to cancel the display. In addition, you can search and filter output from this prompt.

At the --More-- prompt, you can press the forward slash key ( / ) and then enter a search string. The
Brocade device displays output starting from the first line that contains the search string, similar to the
begin option for show commands. An example is given below.

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.
