Dell Force10 E1200i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 43

Command History FTOS maintains a history of previously-entered commands for each mode. For example: • When you are in EXEC mode, the UP and DOWN arrow keys display the previously-entered EXEC mode commands. • When you are in CONFIGURATION mode, the UP or DOWN arrows keys recall the previously-entered CONFIGURATION mode commands. Filtering show Command Outputs Filter the output of a show command to display specific information by adding | [except | find | grep | no-more | save] specified_text after the command. The variable specified_text is the text for which you are filtering and it IS case sensitive unless the ignore-case sub-option is implemented. Starting with FTOS 7.8.1.0, the grep command accepts an ignore-case sub-option that forces the search to case-insensitive. For example, the commands: • show run | grep Ethernet returns a search result with instances containing a capitalized "Ethernet," such as interface GigabitEthernet 0/0. • show run | grep ethernet would not return that search result because it only searches for instances containing a non-capitalized "ethernet." Executing the command show run | grep Ethernet ignore-case would return instances containing both "Ethernet" and "ethernet." • grep displays only the lines containing specified text. The following example shows this command used in combination with the command show linecard all. FTOS(conf)#do show linecard all | grep 0 0 not present Note: FTOS accepts a space or no space before and after the pipe. To filter on a phrase with spaces, underscores, or ranges, enclose the phrase with double quotation marks. • except displays text that does not match the specified text. The following example shows this command used in combination with the command show linecard all.
