find
searches for the first occurrence of a pattern
grep
displays text that matches a pattern.
no-more
does not paginate the display output
save
copies the output to a file for future use
The grep command option has an ignore-case sub-option that makes the search case-insensitive. For
example, the commands:
Displaying All Output
To display the output all at once (not one screen at a time), use the
no-more
option after the pipe. This
operation is similar to the
terminal length screen-length
command except that the
no-more
option affects the output of just the specified command. For example:
Dell#show running-config|
no-more
.
Filtering the Command Output Multiple Times
You can filter a single command output multiple times. To filter a command output multiple times, place
the
save
option as the last filter. For example:
Dell# command | grep regular-expression |
except regular-expression | grep other-regular-expression | find regular-
expression | no-more | save
.
Command Modes
To navigate and launch various CLI modes, use specific commands. Navigation to these modes is
described in the following sections.
EXEC Mode
When you initially log in to the switch, by default, you are logged in to EXEC mode. This mode allows you
to view settings and enter EXEC Privilege mode, which is used to configure the device.
When you are in EXEC mode, the > prompt is displayed following the host name prompt, which is “Dell”
by default. You can change the host name prompt using the
hostname
command.
NOTE: Each mode prompt is preceded by the host name.
EXEC Privilege Mode
The
enable
command accesses EXEC Privilege mode. If an administrator has configured an “Enable”
password, you are prompted to enter it.
EXEC Privilege mode allows you to access all the commands accessible in EXEC mode, plus other
commands, such as to clear address resolution protocol (ARP) entries and IP addresses. In addition, you
can access CONFIGURATION mode to configure interfaces, routes and protocols on the switch. While
you are logged in to EXEC Privilege mode, the # prompt displays.
