Use alias to configure a command alias.
Use undo alias to delete a command alias.
Syntax
alias alias command

Default
The device has a set of system-defined command aliases, as listed in Table 1.

Parameters
alias: Specifies an alias, a case-sensitive string of 1 to 20 characters. An alias cannot be alias or
contain spaces.
command: Specifies a command string. Make sure the command string meets the syntax
requirements.
Usage guidelines
System-defined command aliases cannot be deleted.
You can configure one or more aliases for a command or the starting keywords of commands. Then,
you can use the aliases to execute the command or commands. If the command or commands have
undo forms, you can also use the aliases to execute the undo command or commands.
For example, if you configure the alias shiprt for display ip routing-table, you can enter shiprt to
execute the display ip routing-table command. If you configure the alias ship for display ip, you
can use ship to execute all commands that start with display ip:

2
•
Enter ship routing-table to execute the display ip routing-table command.
•
Enter ship interface to execute the display ip interface command.
The command string can include up to nine parameters. Each parameter starts with the dollar sign
($) and a sequence number in the range of 1 to 9. For example, you can configure the alias shinc for
the display ip $1 | include $2 command. Then, to execute the display ip routing-table | include
Static command, you only need to enter shinc routing-table Static. To execute the display ip
interface | include GigabitEthernet0/0/1 command, you only need to enter shinc interface
GigabitEthernet0/0/1.
Examples
# Configure the alias shiprt for the display ip routing-table command and verify the configuration.
<Sysname> system-view
[Sysname] alias shiprt display ip routing-table

Parameters
command: Specifies the keywords and arguments of a display command. To display available
keywords and arguments, enter display ?.
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
Use the | { begin | exclude | include } regular-expression option with a display command to filter
the command output. For more information about regular expressions, see Fundamentals
Configuration Guide.
Examples
# Display the lines that contain vlan in the running configuration.
<Sysname> display current-configuration | include vlan
vlan 1
vlan 999
port access vlan 999
display | by-linenum
Use display | by-linenum to number each output line for a display command.

Parameters
command: Specifies the keywords and arguments of a display command. To display available
keywords and arguments, enter display ?.
Usage guidelines
By numbering each output line from a display command, you can easily identify the lines of interest.
Each line number is displayed as a 5-character string and might be followed by a colon (:) or hyphen
(-). If you specify both | by-linenum and | begin regular-expression for a display command, a
hyphen is displayed for all lines that do not match the regular expression.

Parameters
command: Specifies the keywords and arguments of a display command. To display available
keywords and arguments, enter display ?.
filename: Specifies the name of the file that is used to save the output, a string of 1 to 63 characters.
Usage guidelines
The display commands show the configuration, statistics, and states of the device. You can use the
display >command to save the output to a file.
If the specified file does not exist, the system creates the file and saves the output to the file. If the file
already exists, the system overwrites the file.
Examples
# Save VLAN 1 settings to a separate file named vlan.txt.
<Sysname> display vlan 1 > vlan.txt
# Check the content of the vlan.txt file.
<Sysname> more vlan.txt

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

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.
Examples
# Display all commands saved in the command history buffer for the current CLI session.
<Sysname> display history-command
system-view

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
display history-command all
Views
Any view
Predefined user roles
network-admin
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.

8
A user logout does not cause the system to delete commands from the history buffer for all CLI
sessions.
Examples
# Display all commands saved in the command history buffer for all CLI sessions.
<Sysname> display history-command all

Parameters
number: Specifies the number of the most recently executed commands in the command history
buffer for the current CLI session that you want to execute. The value range is 1 to 10. The default is
1.
count times: Specifies the number of times that you want to execute the commands. The value
range is 0 to 4294967295. The default is 0. If you do not specify this option, the system keeps
executing the commands until you press the escape key to terminate the execution.
delay seconds: Specifies the time (in seconds) for the system to wait before executing the
commands again. The value range is 0 to 4294967295. The default is 1.
Usage guidelines
To repeat a command, first enter the view for the command. To repeat multiple commands, first enter
the view for the first command.
The repeat command executes commands in the order they were executed.
The system waits for your interaction when it repeats an interactive command.
Examples
# Configure the system to execute the two most recently executed commands (display cpu and
display clock) three times at an interval of 10 seconds.
<Sysname> repeat 2 count 3 delay 10
