Basic CLI commands
display [ | [ by-linenum ] { begin | exclude | include } ]
Use display [ | [ by-linenum ] { begin | exclude | include } to filter the output from
a display command with a regular expression.
Syntax
display command [ | [ by-linenum ] { begin | exclude | include }
regular-expression ]&<1-128>

Parameters
command: Specifies the keywords and arguments of a display command. To display available
keywords and arguments, enter display ?.
[ | [ by-linenum ] { begin | exclude | include } regular-expression ]&<1-128>:
Specifies a maximum of 128 filter conditions.
•
by-linenum: Numbers the output lines. You need to specify this keyword in only one filter
condition.
•
begin: Displays the first line matching the specified regular expression and all subsequent
lines.
•
exclude: Displays all lines not matching the specified regular expression.
•
include: Displays all lines matching the specified regular expression.
•
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256
characters.
Usage guidelines
To quickly locate certain lines in the output from a display command, you can use regular
expressions to filter the output, and display a number before each output line. For more information
about regular expressions, see Fundamentals Configuration Guide.
If you specify multiple filter conditions, the system displays the output lines that meet all the
conditions.
A line number is a 5-character string and is typically followed by a colon (:). If you specify both the
by-linenum and begin regular-expression options, a line number might be followed by a
colon or a hyphen (-).
•
Colon—The line matches the regular expression.
•
Hyphen—The line does not match the regular expression.
Examples
# Display the lines that contain vlan in the running configuration.
<Sysname> display current-configuration | include vlan
vlan 1

display history-command
Use display history-command to display all commands that are saved in the command history
buffer for the current CLI session.
Syntax
display history-command
Views
Any view
Predefined user roles
network-admin
network-operator
Usage guidelines
The system automatically saves commands you have successfully executed to the command history
buffer for the current CLI session. You can view them and execute them again.
By default, the system can save up to 10 commands in the buffer. You can use the
history-command max-size command to change the buffer size. To buffer a new command
when the buffer is full, the system deletes the oldest command entry in the buffer.
All commands in the command history buffer for the current CLI session will be cleared when you log
out.
If the command history buffer contains password configuration commands, the passwords are
displayed as asterisks (******) for security purposes.
Examples
# Display all commands saved in the command history buffer for the current CLI session.
<Sysname> display history-command
system-view
vlan 2
quit

display history-command all
Use display history-command all to display all commands that are saved in the command
history buffer for all CLI sessions.
Syntax

Usage guidelines
The system automatically saves commands successfully executed by users to the command history
buffer for all CLI sessions. Users can view them but cannot recall them from the buffer.
Up to 1024 commands can be saved in the command history buffer. To buffer a new command when
the buffer is full, the system deletes the oldest command entry in the buffer.
A user logout does not cause the system to delete commands from the history buffer for all CLI
sessions.
If the command history buffer contains password configuration commands, the passwords are
displayed as asterisks (******) for security purposes.
Examples
# Display all commands saved in the command history buffer for all CLI sessions.
<Sysname> display history-command all

Usage guidelines
The device supports a set of hotkeys. Pressing a hotkey executes the command or function assigned
to the hotkey. You can configure all the hotkeys except Ctrl+].
A hotkey can correspond to only one command or function. If you assign multiple commands or
functions to the same hotkey, the most recently assigned command or function takes effect.
A command or function can be assigned to multiple hotkeys. You can use any of those hotkeys to
execute the command or function.
If a hotkey is also defined by the terminal software you are using to interact with the device, the
terminal software definition takes effect.
Examples
# Assign move_the_cursor_to_the_beginning_of_the_line function to hotkey Ctrl+U.
<Sysname> system-view
[Sysname] hotkey ctrl_u function move_the_cursor_to_the_beginning_of_the_line

Number of the most recently executed commands in the command history buffer specified by
the repeat command.
•
Size of the command history buffer specified by the history-command max-size
command.
•
Number of the commands in the command history buffer.

return
Use return to return to user view from any other view except Tcl configuration view and the Python
shell.
Syntax
return
Views
Any view except user view, Tcl configuration view, and the Python shell
Predefined user roles
network-admin
network-operator
Usage guidelines
In any view except user view, Tcl configuration view, and the Python shell, pressing Ctrl+Z has the
same effect as the return command.
To return to user view from Tcl configuration view, use the tclquit command.
To return to user view from the Python shell, use the exit() command.
Examples
# Return to user view from HundredGigE 1/0/1 interface view.
[Sysname-HundredGigE1/0/1] return
<Sysname>
screen-length disable
Use screen-length disable to disable pausing between screens of output for the current CLI
session.
Use undo screen-length disable to enable pausing between screens of output for the
current CLI session.
Syntax
screen-length disable
undo screen-length disable
Default
The default depends on the configuration of the screen-length command in user line view.
The following are the default settings for the screen-length command:
•
Pausing between screens of output.
•
Displaying up to 24 lines on a screen.
Views
User view
Predefined user roles
network-admin
12
Usage guidelines
If you disable pausing between screens of output, all output is displayed. The screen is refreshed
continuously until the final screen is displayed. As a best practice, disable pausing between screens
of output when you collect information and enable pausing between screens of output when you view
information.
This command takes effect only for the current CLI session. When you are logged out, the default is
restored.
Examples
# Disable pausing between screens of output for the current CLI session.
<Sysname> screen-length disable

Views
User view
Predefined user roles
network-admin
network-operator
Parameters
exclusive: Specifies exclusive-mode system view.
immediate: Specifies real-time-mode system view.
private: Specifies private-mode system view.
Usage guidelines
You can enter real-time-mode system view, exclusive-mode system view, or private-mode system
view.
•
In real-time-mode system view and its lower-level views, settings are written to the running
configuration and take effect immediately.
•
In exclusive-mode system view, private-mode system view, and their lower-level views, settings
are saved to the target configuration, which takes effect after being committed by using the
commit command.
Only one user can enter exclusive-mode system view or its lower-level views.
•
When a user is in an exclusive-mode view, users in private-mode views cannot commit their
target configuration command lines.
•
When no user is in an exclusive-mode view, users in private-mode views can commit their
respective target configuration command lines. However, only one user in a private-mode view
can commit target configuration command lines at a time.
Unless otherwise stated, entering system view refers to entering real-time-mode system view.
Private-mode views and exclusive-mode views have a leading tilde sign (~) in their prompts as
compared to their counterpart real-time-mode views.
