Command History
The Dell EMC 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 specic 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 ltering and it IS case sensitive unless you use the ignore-case sub-
option.
Starting with Dell EMC 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
GigabitEthernet 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 specied text. The following example shows this command used in combination with
the
show system brief command.
Example of the grep Keyword
DellEMC(conf)#do show system brief | grep 0
0 not present
NOTE
: Dell EMC 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.
