To facilitate maintenance of the network device, a user may send commands through a command line interface. Generally, a user may access a network device to be maintained through a connection manner such as a console and telnet, and input a command (command, which is composed of several command parameters) through a command line interface (command line interface, which is an interactive terminal interface) to implement maintenance of the network device.
Since the commands for maintaining the network device by the user are more and more complicated at present, the user may not know the complete command parameters included in the command to be input when inputting a certain command. In order to solve the problem, a user can firstly check prompt information corresponding to command parameters forming the command through a command line interface and input a correct command based on the prompt information.
Therefore, a method for outputting command parameter prompt information based on a command line interface is needed.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items. It should also be understood that the word "if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination," depending on the context.
In the related art, the commands for maintaining the network devices are generally pre-defined by a developer. It should be noted that the above command generally consists of several command parameters; the command parameters may include fixed command parameters and variable command parameters; wherein, the fixed command parameter can represent the same content in different commands; for example, ip (a fixed parameter) may indicate the same content "ip address" in different commands. The variable command parameter generally indicates different contents in different commands, and the variable command parameter generally indicates a type of parameter having the same format characteristic. For example, a.b.c.d (variable parameter) may be used to represent a parameter having an IPv4 address format, YYYY-MM-DD may be used to represent a parameter having a date format, and ENUMNAME may be used to represent an interface number.
Usually, when defining a command, a developer will also define prompt information corresponding to the command parameters constituting the command. The prompt message can be used for explaining the meaning of the command parameter corresponding to the prompt message to the user.
When the command parameter corresponding to the prompt information is a fixed command parameter (the prompt information corresponding to the fixed command parameter is usually information that is not frequently modified), the prompt information may be defined in the description information (attribute information) corresponding to the fixed command parameter; when the command parameter is a variable command parameter, on one hand, when the prompt message is a prompt message that does not need to be modified frequently, the prompt message may be defined in the description information (attribute information) corresponding to the variable command parameter; on the other hand, when the prompt message is a prompt message that needs to be modified frequently (when the service requirement is increased, the prompt message is also changed accordingly), the variable command parameter and the corresponding prompt message may be defined in the configuration file corresponding to the command. In one embodiment, the configuration file may be a help function defined by a developer for ease of interpreting commands.
The following describes steps of a user querying for commands based on a command line interface (system commands are already maintained in the system, and reference to system commands in this application includes commands defined by developers, as well as commands included by the system itself).
When a user needs to query a command through the command line interface, the user may first input "command keyword a? "is used.
When the system operating the command line interface receives the query instruction, the system can screen out the commands comprising the command parameters A from the database, and display the next command parameter adjacent to the command keyword A and the corresponding prompt information in the commands meeting the conditions.
The user can continue to input "command keyword B? "a query instruction; the command keyword B is input by a user based on the displayed content, and the command keyword B includes the command keyword a and a next command parameter adjacent to the command keyword a.
When the system receives the query command continuously input by the user, the system can screen out the command comprising the command parameter B from the database, and display the next command parameter adjacent to the command keyword B and the corresponding prompt information in the command meeting the condition.
The user can repeatedly input the query instruction based on the display content until the self-required command is obtained.
It should be noted that, when the prompt information corresponding to the command parameter is obtained in the above step, the system may first determine whether the command parameter is a variable command parameter; if not, directly taking the description information corresponding to the command parameter as the prompt information of the command parameter; if so, matching the command parameter with the variable command parameter in the configuration file corresponding to the command, and if the command parameter is matched with any variable command parameter, taking the prompt information corresponding to the variable command parameter in the configuration file in the matching process as the prompt information corresponding to the command parameter.
For example, assume that the command that the user needs to query is "Enable interface ENUMNAME" (the command is maintained in the system). The command comprises 4 command parameters; wherein, the 'Enable' and 'interface' are fixed command parameters; "ENUMNAME" is a variable command parameter. The description information corresponding to "Enable" is "Enable interface" and the description information corresponding to interface "is null, and the correspondence between the variable command parameters and the prompt information in the configuration file corresponding to the command is shown in table 1.
| Variable command parameters | Prompt information |
| ENUMNAME | input 1-16 |
TABLE 1
When the user inputs "Enable? When the command is queried, the system can screen out a command ("Enable interface ENUMNAME") including a command parameter "Enable" by querying the database, and display the next command parameter (in this example, the command parameter is "interface") adjacent to the "Enable" and prompt information corresponding to the command parameter ("interface") in the eligible commands.
When the prompt message corresponding to the interface is obtained, because the interface is not a variable command parameter, the description message corresponding to the command parameter (if the description message corresponding to the fixed command parameter is empty, the prompt message corresponding to the fixed command parameter may not be displayed) may be directly used as the prompt message of the command parameter.
Thereafter, the user can continue to enter "Enable interface? "is used. When the system receives the query instruction, the database may include a command with a command parameter "Enable", and display a next command parameter (in this example, the command parameter is "ENUMNAME") adjacent to the interface among the commands that meet the condition, and prompt information corresponding to the command parameter ("ENUMNAME").
When the prompt information corresponding to "ENUMNAME" is acquired, since "ENUMNAME" is a variable command parameter, the command parameter is matched with the variable command parameter in the configuration file (as shown in table 1) corresponding to the command. In this example, "ENUMNAME" can match the variable command parameter "ENUMNAME" in the configuration file, and thus "input 1-16" can be used as the prompt information corresponding to the command parameter "ENUMNAME".
Thus, the user acquires the complete command "Enable interface ENUMNAME".
Therefore, through the steps, the user can obtain the command required by the user.
However, on the one hand, assume that the command that the user needs to query is "replace ip a.b.c.d with a.b.c.d" (the command is already maintained in the system). The command comprises 5 command parameters; wherein, the "place", "ip" and "with" are fixed command parameters; "a.b.c.d" is a variable command parameter. The description information corresponding to the place is place A with B; the description information corresponding to the 'ip' is 'ip address'; the description information corresponding to "with" is empty. The correspondence between the variable command parameters and the prompt information in the configuration file corresponding to the command "place ip a.b.c.d with a.b.c.d" is shown in table 2.
| Variable command parameters | Prompt information |
| A.B.C.D | input 192.168.1.1 |
| A.B.C.D | input 1.1.1.1 |
TABLE 2
When the user inputs "place ip? After the query instruction, the system needs to acquire the prompt information corresponding to the "a.b.c.d". Since "a.b.c.d" is a variable command parameter, the system needs to match "a.b.c.d" with a variable command parameter in a configuration file corresponding to the command, and if the command parameter matches any variable command parameter, take the prompt information corresponding to the matched variable command parameter in the configuration file as the prompt information corresponding to the command parameter. However, since the same variable command parameter "a.b.c.d" corresponds to different prompt information in the correspondence relationship shown in table 2, the system cannot determine which prompt information in the configuration file should be acquired as the prompt information corresponding to the variable command parameter "a.b.c.d".
On the other hand, since the variable command parameter is usually in the form of a character string, when the prompt information corresponding to the command parameter is determined by matching the variable command parameter in the configuration file corresponding to the command, the work efficiency is low.
Based on the above, the application provides a method for outputting command parameter prompt information based on a command line interface, which can be applied to an operating system. The method can mark the same command parameter in the command by using different command parameter identifications, so that the prompt message uniquely corresponding to the command parameter can be determined in the configuration file by the command parameter identification.
In implementation, please refer to fig. 1, where fig. 1 is a flowchart of a method for outputting command parameter prompt information based on a command line interface according to the present application. The method can be applied to an operating system, and command parameters included in system commands for system maintenance are respectively marked with command parameter identifiers; wherein, the same command parameters included in the system commands are respectively marked with different command parameter identifications; as shown in fig. 1, the method includes:
s101, acquiring a command keyword input by a user on the command line interface;
s102, responding to the command keyword, and determining a target system command of the system command maintained by the system, wherein the target system command comprises the command keyword;
s103, matching the command parameter identification marked by the target command parameter corresponding to the command keyword in the target system command with the prompt information identification in the configuration file corresponding to the target system command;
and S104, outputting the prompt information corresponding to the matched prompt information identifier as the prompt information of the target command parameter.
According to the scheme, the command parameter identifications are respectively marked due to the command parameters included in the system commands for system maintenance; when the prompt information corresponding to the target command parameter is obtained through the configuration file, the command parameter identifier marked by the command parameter is matched with the prompt information identifier in the configuration file, and the prompt information corresponding to the matched prompt information identifier is output as the prompt information of the target command parameter, so that the prompt information corresponding to the command parameter in the configuration file can be definitely determined, and the situation that the prompt information corresponding to the command parameter in the configuration file cannot be determined is avoided.
This embodiment will be described below with reference to specific examples.
Referring to fig. 2, fig. 2 is a structural diagram of an operating system according to the present application. As shown in FIG. 2, the operating system may include a command line page module 210, a hints information determination module 220 coupled to the command line page module 210, and a command set module 230 coupled to the hints information determination module 220. The functions of the modules may be crossed, and are not limited herein.
The command line page module 210 may be configured to receive command keyword information input by a user, and display command parameter prompt information corresponding to the command keyword. For example, a user may enter "command parameters? ".
The prompt information determining module 220 may be configured to determine a command parameter to be prompted according to the command received by the command line page module 210, and prompt information corresponding to the command parameter.
The command set module 230 may store commands defined in the operating system and commands carried by the operating system.
Here, it is necessary to describe a procedure of defining a command and defining prompt information corresponding to command parameters constituting the command in the present embodiment. The prompt information may be used to interpret the corresponding command parameter.
When defining a command, the command parameters included in the command can be marked with command parameter identifications respectively; wherein, the same command parameters included in the system command are respectively marked with different command parameters. In an embodiment, in order to improve the work efficiency of determining the prompt information corresponding to the command parameter by matching the prompt information identifier in the configuration file, a character may be used as the command parameter identifier.
For example, assume that when defining a command of "replace ip a.b.c.d with a.b.c.d", a character "0" may be selected to correspond to "replace", a character "1" may correspond to "ip", a character "i" may correspond to a previous command parameter "a.b.c.d", a character "3" may correspond to "with", and a character "j" may correspond to a next "a.b.c.d". In an embodiment, the identifiers may form an identifier set, and the identifiers in the identifier set may be global variables. In the above situation, the "place ip a.b.c.d with a.b.c.d" command may correspond to an identification set {0, 1, 'i', 3, 'j' } composed of global variable identifications, and command parameters in the command correspond to elements in the identification set one to one. The characters corresponding to the command parameters in the command may be any characters, and the same command parameter in the same command needs to correspond to different characters.
After the command definition is completed, prompt information corresponding to command parameters forming the command can be defined. The prompt message can be used for explaining the meaning of the command parameter corresponding to the prompt message to the user.
When defining the prompt information corresponding to the command parameters constituting the command, it may be determined whether the prompt information corresponding to the command parameters constituting the command needs to be modified frequently.
When the prompt information of the command parameter does not need to be modified frequently, the prompt information corresponding to the command parameter can be defined in the description information (attribute information) corresponding to the command parameter;
when the prompt information of the command parameter needs to be modified frequently, the prompt information corresponding to the command parameter can be defined in the configuration file corresponding to the command. Specifically, a command parameter identifier corresponding to the command parameter may be used as a prompt information identifier, and corresponds to the prompt information of the command parameter; then, the prompt message identifier and the prompt message of the command parameter are defined in the configuration file.
For example, assume that a command "place ip a.b.c.d with a.b.c.d" has been defined; the command corresponds to a flag set of {0, 1, 'i', 3, 'j' }. In the above command, the prompt information corresponding to "place" is "place a with B"; the prompt message corresponding to the 'ip' is 'ip address'; the prompt message corresponding to the "with" is empty; the prompt information corresponding to the former "a.b.c.d" is "input 192.168.1.1", and the prompt information corresponding to the latter "a.b.c.d" is "input 1.1.1.1"; the prompt messages of the "place", "ip" and "with" are prompt messages which do not need to be modified frequently; the hint information of "a.b.c.d" is hint information that needs to be modified often.
When defining the prompt information corresponding to the command parameters constituting the command, the prompt information of "place", "ip", and "with" may be defined in the description information corresponding to each of the command parameters, respectively; the previous prompt message "input 192.168.1.1" of "a.b.c.d" may correspond to the prompt message identifier "i" and be defined in the configuration file corresponding to the command, and the next prompt message "input 1.1.1.1" of "a.b.c.d" may correspond to the prompt message identifier "j" and be defined in the configuration file corresponding to the command. The corresponding relationship between the prompt information identifier and the prompt information in the configuration file may be as shown in table 3.
| Prompt message identification | Prompt information |
| i | 192.168.1.1 |
| j | 1.1.1.1 |
TABLE 3
The following steps for a user to query for commands based on the command line interface.
Specifically, when the user needs to view the prompt information through the command line interface, the user can input "command keyword a? ". For example, a user may enter "replace" through the command line page module 210 described above? ".
At this time, the prompt information determining module 220 may execute S101, acquire a command keyword a input by the user on the command line interface, and then determine, in response to the command keyword a, a target system command including the command keyword a in the system commands maintained by the system.
In implementation, after the completion of the execution of S101, the prompt information determination module 220 may access the command set module 230 to obtain the command including the command keyword a from the commands stored in the command set module. For example, a user enters "place? After that, the prompt information determining module 220 may obtain a "replace ip a.b.c.d with a.b.c.d" command.
The hint information determination module 220 may then determine a target command parameter corresponding to the command key a in the target system command. In an embodiment, the target command parameter corresponding to the command keyword a in the target system command is a next command parameter adjacent to the command keyword a in the target system command.
After determining the target command parameter, matching the command parameter identifier marked by the target command parameter with the prompt information identifier in the configuration file corresponding to the target system command;
if the target command parameter is marked by the command parameter identifier and matches any prompt message identifier in the configuration file, outputting the prompt message corresponding to the matched prompt message identifier as the prompt message of the target command parameter;
and if the target command parameter is marked by the command parameter identifier and is not matched with any prompt information identifier in the configuration file, outputting the description information corresponding to the target command parameter as the prompt information of the target command parameter.
After determining the prompt information, the prompt information determining module 220 may output the prompt information to the command line interface module 210 to display the prompt information.
After the user sees the display information, the user can continue to input "command keyword B? "is a query instruction; the command keyword B is input by a user based on the displayed content, and the command keyword B includes the command keyword a and a next command parameter adjacent to the command keyword a. After the user inputs the query instruction, the command line page module 210, the prompt information determination module 220, and the command set module 230 may perform the foregoing steps in a coordinated manner until new prompt content is displayed, and the user may repeatedly input the query instruction based on the new prompt content until a command required by the user is obtained. Therefore, the user can obtain the command which needs to be inquired.
For example, assume that the command "replace ip a.b.c.d with a.b.c.d" has been maintained in the system; the identification set corresponding to the command is {0, 1, 'i', 3, 'j' }; in the above command, the description information corresponding to "place" is "place a with B"; the description information corresponding to the 'ip' is 'ip address'; the description information corresponding to "with" is null; the corresponding relationship between the prompt information identifier and the prompt information in the configuration file corresponding to the command is shown in table 3.
In the above situation, the user inputs "place? After that, the prompt information determining module 220 may obtain a "replace ip a.b.c.d with a.b.c.d" command. Then, the prompt information determining module 220 may determine that the target command parameter is "ip", and match a character "1" corresponding to "ip" with the prompt information identifier in the configuration file; since the hint information identifier in table 3 does not have the character "1", the hint information corresponding to "ip" is the description information "ip address" of the command parameter. After determining the prompt information, the prompt information determining module 220 may output the prompt information to the command line interface module 210 to display the prompt information. At this time, the user will see the prompt contents of "ip" and "ip address".
After obtaining the prompt content, the user can continue to input "replace ip? ". When the prompt information corresponding to the previous "a.b.c.d" needs to be acquired (the previous steps are not described in detail), since the command parameter identifier "i" corresponding to the "a.b.c.d" matches with the prompt information identifier "i" in the configuration file corresponding to the command, "input 192.168.1.1" will be prompted as the prompt information of the previous command parameter "a.b.c.d". At this time, the user will see the prompt contents of "a.b.c.d", "input 192.168.1.1".
After that, the user may repeatedly input the query instruction based on the new prompt content, and when determining the prompt information corresponding to the next "a.b.c.d" (the previous steps are not described in detail), since the command parameter identifier "i" corresponding to the "a.b.c.d" matches with the prompt information identifier "j" in the configuration file corresponding to the command, "input 1.1.1.1" will be prompted as the prompt information of the next command parameter "a.b.c.d". At this time, the user will see the prompt contents of "a.b.c.d", "input 1.1.1.1".
Until the command 'place ip A.B.C.D with A.B.C.D' required by the user is obtained.
Here, it should be noted that, when using the above commands, the user can input "place ip 192.168.1.1with 1.1.1.1" in the command line interface to input valid commands.
According to the scheme, on one hand, the command parameter identifications are marked respectively due to the command parameters included in the system commands for system maintenance; when the prompt information corresponding to the target command parameter is obtained through the configuration file, the command parameter identifier marked by the command parameter is matched with the prompt information identifier in the configuration file, and the prompt information corresponding to the matched prompt information identifier is output as the prompt information of the target command parameter, so that the prompt information corresponding to the command parameter in the configuration file can be definitely determined, and the situation that the prompt information corresponding to the command parameter in the configuration file cannot be determined is avoided.
On the other hand, because the command parameter identifier and the prompt message identifier may be characters, the work efficiency may be greatly improved when determining the prompt message corresponding to the command parameter through the configuration file corresponding to the command and the configuration file corresponding to the command.
In an embodiment, the command parameter identifier may indicate that the command parameter identifier corresponds to a command parameter at a position in the command including the command parameter. By distinguishing the same command parameter by using different position identifiers, the prompt message uniquely corresponding to the command parameter can be determined by the command parameter identifier.
In an embodiment, in order to make the method provided by the present application compatible, the prompt information for obtaining the target command parameter may be compatible with the existing related technologies, after S101-S102 is completed, it may be determined whether the identifier set corresponding to the command is an empty set, and if not, the steps of S101-S104 are performed; if it is an empty set, the existing correlation technique is performed.
In an embodiment, a specific flag may be preset, and after the execution of S101 to S102 is completed, it may be determined whether a command parameter flag indicating a target command parameter corresponding to the command keyword in the target system command is the specific flag.
If the command parameter identification marked by the target command parameter is not the specific identification, executing S103-S104;
matching the command parameter identification marked by the target command parameter corresponding to the command keyword in the target system command with the prompt information identification in the configuration file corresponding to the target system command;
if the command parameter mark marked by the target command parameter is the specific mark, the description information corresponding to the target command parameter is output as the prompt information of the target command parameter.
As can be seen from the above steps, when the command parameter identifier marked by the target command parameter is the specific identifier, the steps S103-S104 do not need to be executed, and the description information corresponding to the target command parameter is acquired as a prompt to you, so that the efficiency of acquiring the prompt information corresponding to the command parameter can be effectively improved.
Corresponding to the above method embodiment, the present application further provides a device for outputting prompt information based on a command line interface, which is applied to an operating system, and command parameters included in system commands maintained by the system are respectively marked with command parameter identifiers; wherein, the same command parameters included in the system command are respectively marked with different command parameter identifications.

In an embodiment, the command parameter identifier and the prompt information identifier are character identifiers.

if the command parameter mark marked by the target command parameter is the specific mark, the description information corresponding to the target command parameter is output as the prompt information of the target command parameter.
