Searching and Filtering CLI Output Chapter 1 CLI Overview Send documentation comments to [email protected] Searching and Filtering CLI Output The Cisco MDS SAN-OS CLI provides ways of searching through large amounts of command output and filtering output to exclude information you do not need. These features are enabled for the show command, which generally displays large amounts of data. Note The show command is always entered in EXEC mode. When output continues beyond what is displayed on your screen, the Cisco MDS SAN-OS CLI displays a --More-- prompt. Pressing Return displays the next line; pressing the Spacebar displays the next screen of output. To search the show command output, use the following command in EXEC mode: Command switch# show any-command | begin pattern Purpose Begins unfiltered output of the show command with the first line that contains the pattern. Note Cisco MDS SAN-OS documentation generally uses the vertical bar to indicate a choice of syntax. However, to search the output of the show command, you need to enter the pipe character (the vertical bar). In this section the pipe appears in bold (|) to indicate that you should enter this character. To filter show command output, use one of the following commands in EXEC mode: Command Purpose switch# show any-command | exclude pattern Displays output lines that do not contain the pattern. switch# show any-command | include pattern Displays output lines that contain the pattern. switch# show any-command | include "pattern1|pattern2" Displays output lines that contain either pattern1 or pattern2. Note The alternation patterns, "pattern1|pattern2", must appear within double quotes. switch# show any-command | include pattern [next number] [prev number] Displays output lines that contain the pattern. Optionally, using the next or prev parameter followed by a number also displays the designated number of lines. switch# show any-command | count number Displays the number lines of output in the display. 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.
