Command execution result analysis method and system based on virtual terminal

Abstract

The invention discloses a command execution result analysis method and system based on a virtual terminal, belongs to the technical field of command batch processing, and aims to solve the technical problems of how to analyze a command execution result, remove invalid characters, process a data dependency relationship between commands and effectively extract valid data. Comprising the following steps: after a command is sent to target equipment, creating a virtual terminal window in a memory; the returned command execution result data is added to the virtual terminal window, the command execution result data comprises text characters and control characters, and the control characters comprise characters in an ANSI format and a VT100 format; analyzing and screening the command execution result data, removing the control characters, retaining the extracted text characters in the memory, and formatting the text characters based on the control characters to obtain final command execution result data; and analyzing the final command execution result data, and extracting effective command execution result information.

Description

technical field [0001] The invention relates to the technical field of command batch processing, in particular to a method and system for analyzing command execution results based on a virtual terminal. Background technique [0002] In the communication network operation and maintenance work, it is often necessary to perform batch processing operations on multiple network devices or host devices. A common operation is to automatically execute a batch of commands in an unattended manner. The general steps of traditional batch processing operations are to issue a command, receive the command result and judge whether it contains the command terminator, and if it contains the command terminator, issue the next command, and so on, until all commands are executed. The traditional batch processing method is convenient to implement, but there are several problems, such as: [0003] (1) When there is no command terminator in the execution result or the command terminator is included...

AI Technical Summary

Problems solved by technology

[0003] (1) When there is no command terminator in the execution result or the command terminator is included in other positions in the result, the position of the terminator cannot be effectively judged, resulting in incomplete command results or out-of-order batch execution;

[0004] (2) The execution result contains not only readable text characters, but also ANSI and VT100 terminal control characters. These control characters are mixed in the normal text results, which not only interfere with the judgment of the command terminator, but also cause a large number of recorded results to appear The garbled characters are not conducive to analyzing the command execution results;

[0005] (3) The data dependencies between commands cannot be handled. Sometimes, the input parameters when the next command is executed depend on the data in the execution result of the previous command
