Chapter 1 CLI Overview
Searching and Filtering CLI Output
To filter show command output, use one of the following commands in EXEC mode:
You can enter the Ctrl-Z key combination at any time to interrupt the output and return to EXEC mode.
For example, you can enter the show running-config | begin hostname command to start the display of
the running configuration file at the line containing the hostname setting, then use Ctrl-Z when you get
to the end of the information you are interested in capturing. See the “Searching and Filtering CLI
Output Examples” section on page 1-21.
Multiple Filter Commands
Cisco MDS SAN-OS Release 2.1(1a) supports using multiple filters in the same show command output.
This means you can use a combination of the available filters to format the output of any show command.
Note The maximum number of commands allowed is four. For example, you can enter a maximum of three
filter commands or two filter commands and a redirection.
Cisco MDS SAN-OS Release 2.1(1a) also supports both filters and redirection in the same command.
Now you can apply the required filters to the output of any command, and save the output using the file
redirection. See the next section, “Searching and Filtering CLI Output Examples” section on page 1-21.
Searching and Filtering CLI Output Examples
