Dell S6100, Configuration Manual

Page: 45 / 1743

The CLI prompt changes as you move up and down the levels of the command structure. Starting with CONFIGURATION mode, the
command prompt adds modifiers to further identify the mode. For more information about command modes, see
Command Modes .
Using the Keyword no Command
To disable, delete or return to default values, use the
no
form of the commands.
For most commands, if you type the keyword
no
in front of the command, you disable that command or delete it from the running
configuration. In this guide, the
no
form of the command is described in the Syntax portion of the command description.
Filtering show Commands
You can filter commands using the
show
command to find specific information, display certain information only, or begin the command
output at the first instance of a regular expression or phrase.
Execute a
show
command and a pipe ( | ), and one of the following parameters and a regular expression to show output that either
excludes or includes the specified parameters.
NOTE: The Dell Networking OS accepts a space before or after the pipe, no space before or after the pipe, or any combination.
For example:
command | grep gigabit |except regular-expression | find regular-expression
.
except Displays only the text that does not match the pattern (or regular expression).
find Searches for the first occurrence of a pattern.
grep Displays text that matches a pattern.
The
grep command option has an ignore-case suboption that makes the search case-insensitive. For example, the
commands:
show run |
grep Ethernet Returns a search result with instances containing a capitalized Ethernet , such as
interface TenGigabitEthernet 1/1/1/1
.
show run |
grep ethernet Does not return the previous search result because it only searches for instances
containing a noncapitalized
ethernet .
show run |
grep Ethernet
ignore-case Returns instances containing both Ethernet and ethernet .
no-more Does not paginate the display output.
save Copies the output to a file for future use.
Displaying All Output
Use the
no-more
option after the pipe to display all output at once — not one screen at a time. This operation is similar to
terminal
length screen-length
except that the
no-more
option affects the output of just the specified command. For example:
show
running-config|no-more
.
