Command History
The Dell Networking OS 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 you use the ignore-case sub-
option.
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 0/0.
• 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 processes command.
Dell#show processes cpu cp | grep system
0 72000 7200 10000 17.97% 17.81% 17.96% 0 system
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 processes command.
Example of the except Keyword
Dell#show processes cpu cp | except system
