Command History

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

specified_text after the command.

The variable specified_text is the text for which you are ltering 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 would 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 specied text. The following example shows this command used in combination with

the

do show stack-unit all stack-ports all pfc details | grep 0 command.

Dell(conf)#do show stack-unit all stack-ports all pfc details | grep 0

stack unit 0 stack-port all

0 Pause Tx pkts, 0 Pause Rx pkts

NOTE

: Dell Networking OS accepts a space or no space before and after the pipe. To lter a phrase with spaces, underscores, or

ranges, enclose the phrase with double quotation marks.

The except keyword displays text that does not match the specied text. The following example shows this command used in

combination with the

do show stack-unit all stack-ports all pfc details | except 0 command.
