Basic CLI commands
alias
Use alias to configure a command alias.
Use undo alias to delete a command alias.
Syntax
alias alias command
undo alias alias
Default
The device has a set of system-defined command aliases, as listed in Table 1.
Table 1 System-defined command aliases

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.

2
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:
•
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
Twenty-FiveGigE1/0/1 command, you only need to enter shinc interface
Twenty-FiveGigE1/0/1.
Examples
# Configure shiprt as the alias for the display ip routing-table command and verify the
configuration.
<Sysname> system-view
[Sysname] alias shiprt display ip routing-table

a display command with a regular expression.

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
vlan 999
port access vlan 999

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.

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

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.
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
