Configuration Fundamentals | 43Filtering show Command OutputsFilter 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 arefiltering 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 tocase-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 instancescontaining 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. Figure 2-9 shows this command used incombination with the command show linecard all.Figure 2-9. Filtering Command Outputs with the grep Command• except displays text that does not match the specified text. Figure 2-10 shows this command used incombination with the command show linecard all.Figure 2-10. Filtering Command Outputs with the except CommandNote: 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.FTOS(conf)#do show linecard all | grep 00 not presentFTOS#show linecard all | except 0-- Line cards --Slot Status NxtBoot ReqTyp CurTyp Version Ports---------------------------------------------------------------------------2 not present3 not present4 not present5 not present6 not present
