Filtering Show Command Outputs; Example Of The Grep Keyword - Dell S4048T Configuration Manual

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 you use the
ignore-case sub-option.
Starting with Dell Networking OS version 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 TenGigabitEthernet 1/1.
• show run | grep ethernet does not return that search result because it only searches for instances
containing a non-capitalized "ethernet."
• show run | grep Ethernet ignore-case returns instances containing both "Ethernet" and
"ethernet."
The grep command displays only the lines containing specified text. The following example shows this
command used in combination with the show system brief command.
Example of the
Dell(conf)#do show system brief | grep 0
0 not present
NOTE: Dell Networking OS accepts a space or no space before and after the pipe. To filter a phrase with
spaces, underscores, or ranges, enclose the phrase with double quotation marks.
The except keyword displays text that does not match the specified text. The following example shows this
command used in combination with the show system brief command.
Example of the except Keyword
Dell#show system brief | except 1
Stack MAC
Reload-Type
The find keyword displays the output of the show command beginning from the first occurrence of
specified text. The following example shows this command used in combination with the show system
brief command.
Example of the find Keyword
The display command displays additional configuration information.
The no-more command displays the output all at once rather than one screen at a time. This is similar to the
terminal length command except that the no-more option affects the output of the specified command
only.
