Description

A method of processing command line output information based on regular matching

technical field

The invention relates to a command line output information processing method, in particular to a command line output information processing method based on regular matching.

Background technique

The run command is mainly the operation mode of the DOS operating system. Regardless of the windows system or the Linux system, both support the running command mode to obtain the running result information of the system. Especially for various network devices, the device interaction interface provided by the manufacturer basically includes the command mode.

Tools such as SHH and telnet support remote running commands and display the running results of the remote system on the client.

This type of tool generally requires the user to manually input a remote command, and when the remote system executes the command, the display terminal outputs the command execution result.

The command line method can obtain the basic configuration information of the operating system (network device). In a network environment, the remote command line method is a commonly used method to obtain the basic configuration of the operating system.

This approach has the following disadvantages:

1. The user needs to manually input each command line to save the original text data. 2. Different systems or devices require different command lines for the same data results, and the original text data is also different. 3. The user's final result data changes with the specific business. 4. Based on the second shortcoming, the automation program is faced with the problem of how to achieve support for new systems and equipment with maximum ergonomics.

Therefore, it is necessary to improve the prior art.

Description of drawings

The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

FIG. 1 is a schematic flowchart of a method for processing command line output information based on regular matching in the present invention.

Detailed ways

The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

Embodiment 1, the command line output information processing method based on regular matching, as shown in Figure 1, comprises the following steps:

S1. Make a command line list file, a command line regular expression matching table, and a command line result matching table according to the requirements of the corresponding system (equipment). In step S1, the data of the three tables need to be manually set before step S2 can be performed.

Each piece of data in each table contains the following attributes:

The command line list data in the command line list file: the unique identification ID of the command line, the name of the command line, the specific text command of the command line, and the waiting time for the command to expire.

The command line list data of the command line list file only works in the S2 step, and its functions are as follows:

Command line unique ID: generated incrementally, corresponding to the command line unique ID of the command line regular expression matching table; after step S2 is executed, it is saved together with the text result as the original result data. A single piece of data in the command line list file corresponds to multiple pieces of command line regular expression matching table data.

The name of the command line: defines the function type of the command line. After step S2 is executed, it is saved together with the text result as the original result data. Command line names are different, and command execution methods are also different. For example, to log in to the system, you need to enter a user name and password; to obtain system configuration functions, you need to enter commands.

Concrete textual command of the command line: the textual representation of the command line. After step S2 is executed, it is saved together with the text result as the original result data.

Waiting command expiration time: set the maximum time for waiting for the command line to run in step S2. It only applies to the command execution process and is not saved as the original result data.

Command line regular expression matching table data in the command line regular expression matching table: result item name, command line unique identification ID, result item default result value, program method identification symbol, program parameter list, regular expression, intermediate data identifier name.

Each attribute of the command line regular expression matching table works in steps S3 to S8, and its effect is as follows:

Result item name: corresponds to the result item name in the command line result matching table. The set of result item names in the command line result match table is a subset of the result item name set in the command line regular expression match table. Result item names are unique.

Command line unique identification ID: corresponds to the command line unique identification ID of the command line list file. A command line list data must be found through this property.

Result item default result value: save the default processing result data. Used when parsing raw data yields no results.

Program method identification symbol: Different regular expressions have different processing methods, and identification symbols are used to select the processing method.

Program parameter list: parameters passed in when using regular expressions to process data. Different processing methods have different parameters (parameter types and numbers are different), which determine the original data processing method together with the program method identification symbol and regular expression.

Regular expression: The regular expression used to process raw data, together with the program parameter list and program method identifier, determines the raw data processing method.

Intermediate data identification name: When the intermediate data identification name is not empty, the processed data can be saved as intermediate data. The intermediate data is distinguished by the intermediate data identification name. The intermediate data identification name is unique.

The data of the command line list file is created based on the command line list data.

Command line result matching table data in the command line result matching table: result item name, description, result expression format, and whether to display the flag.

Each attribute of the command line result matching table plays a role in steps S3 to S9, and its effect is as follows:

The functions of each attribute of the command line result matching table are as follows:

Result item name: corresponds to the result item name in the command line regular expression matching table. If a certain result depends on other detection results, the command line result matching table needs to add the dependent result item name.

Description: Description of the meaning of the result data.

Result expression: the data format used when the result data is output.

Whether the result shows a flag: Some results are used as intermediate results of other results, and the flag is used to determine whether output is required.

Whether the result of the command line result matching table shows the flag has nothing to do with the intermediate data identification name of the command line regular expression matching table. The former is used for the output of the final result, and the latter is used to judge whether the processed command result can be used as intermediate data.

S2. Cycle through and execute each command in the command line list file (the specific text command attribute of the command line is saved), and obtain the text result of the command execution. If the time spent executing a single command exceeds the waiting command expiration time, the command is interrupted, and empty text is used as the text result of the command execution; if the time spent executing a single command does not exceed the waiting command expiration time, the result text is used as the text result of the command execution.

The list data of each command line and the text result of command execution are saved to the original data collection as the original result data. The raw data set works in steps S3 to S8.

Each piece of original result data includes the unique identification ID of the command line, the name of the command line, the specific text of the command line, and the text result of the command execution, excluding the waiting time for the command to expire.

S3. Extract the data in the command line result matching table, and create a result acquisition circular list (equivalent to a sub-table of the command line result matching table). Through the result item name of a single piece of data in the sub-table, find the command line unique identification ID, regular expression, program method identification symbol, program parameter list, result item default result value and intermediate corresponding to the command line regular expression matching table data The data identifier name. In the process of S2, all command execution results have been obtained, and in S3, the execution result corresponding to each result is determined in reverse by the command line result matching table.

Search the original result data in S2 according to the unique identification ID of the command line, and obtain the text result of the execution of the corresponding command in S2. If the corresponding original result data can be found, execute step S4; otherwise, obtain the data of the next item in the circular list (command line unique identification ID) and retest;

S4. Construct the processing method corresponding to the original data obtained in S3 according to the program method identification symbol, program parameter list, and regular expression determined in S3, analyze and process the text result of the command execution in the original result data according to the processing method, and obtain Parse and process data. Judging whether the parsing and processing data is the final result according to whether the result of obtaining the circular list displays a flag. If it is the final result, the circular list deletes the corresponding result item corresponding to the result item name, and saves the parsing and processing data into the final data, and then executes step S5;

In step S3, the method, parameters, and running results are determined, and in s4, a specific method is constructed through the method parameter template to process the original data corresponding to the result in S3.

If there is a lack of data during the parsing process, such as the lack of intermediate data identification names required for parsing (parsing depends on the execution results of other commands, and the results are not yet in the parsing process), look for the intermediate result data set in the original result data, if not found Intermediate result data, go to step S7.

The final data includes: result item name and parsing and processing data.

S5. According to the intermediate data identification name, judge whether the final result obtained in step S4 can be used as a result to obtain the original data of other result matching items in the circular list, if the intermediate data identification name is not empty, perform step S6; if the intermediate data identification name is empty, go to step S7;

S6. Saving the analysis and processing data of the final data and the corresponding intermediate data identification name into the original data as the intermediate data identification name;

The original data set is divided into two parts, one part is the original result data generated by the S1 step, and the other part is the intermediate result data.

The intermediate result data includes the identification name of the intermediate data and the parsing and processing data in step S4. Intermediate result data are used as parameters by the partial parsing process.

S7. Obtaining the result obtains the unprocessed result item in the circular list (the processed result item has been removed in step S4);

S8. Judging whether the result acquisition cycle list has been completely processed (the list is empty), and the unprocessed data (the list is not empty) jumps to step S3; after processing, execute step S9;

S9. Determine whether the item of data is output data according to whether the result of each item of data in the command line result matching table displays a flag. If it is output data, find the analysis and processing data of the final data through the result item name. Reformat, analyze and process data according to the result expression, and obtain a new final result for each item of data.

Changeable configuration files: command line list, command line regular expression matching table, command result matching table.

The internal specific data format of the command line regular expression matching table and the result command line matching table may vary. The representation forms of the command line regular expression matching table and the result command line matching table may also be different, such as XML files, text files, JSON format files, or database file formats.

Finally, it should be noted that the above examples are only some specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention should be considered as the protection scope of the present invention.
