Problems solved by technology

[0003] Shell commands are usually implemented in the Linux system and require the support of the Linux kernel, and the developed Shell commands need to be installed, that is, corresponding installation packages need to be developed, whether it is a personal computer (Personal Computer, PC) application or an embedded Linux Shell, This is the case, the development workload is heavy, and it involves Linux kernel calls, which makes the system complicated
[0004] For small chips, it is usually unable to carry the Linux system, so small chips generally use a real-time operating system (Real Time Operating System, RTOS). Realize the processing of Shell commands

Abstract

Embodiments of the invention provide a method and an apparatus for processing a computer Shell command. The method for processing the computer Shell command comprises the steps of obtaining the Shellcommand; according to the Shell command, searching for an executive function corresponding to the Shell command in a preset mapping table; and calling the executive function corresponding to the Shellcommand, wherein the preset mapping table comprises a corresponding relationship between the Shell command and the executive function. The Shell command can be processed; for example, the Shell command is processed in a real-time operation system; the executive function corresponding to the Shell command is determined according to the preset mapping table; system files do not need to be installedand called; the realization is simple and convenient; a small chip also can use the Shell command to realize program fault debugging; and the method and the apparatus are suitable to test different software projects.

Description

technical field [0001] The embodiment of the present invention relates to embedded development technology, in particular to a method and device for processing shell commands of a computer. Background technique [0002] As a command language, the computer shell (Shell) interactively interprets and executes commands entered by users, or automatically interprets and executes a series of preset commands. [0003] Shell commands are usually implemented in the Linux system and require the support of the Linux kernel, and the developed Shell commands need to be installed, that is, corresponding installation packages need to be developed, whether it is a personal computer (Personal Computer, PC) application or an embedded Linux Shell, This is the case, the development workload is heavy, and it involves calling the Linux kernel, which makes the system complicated. [0004] For small chips, it is usually unable to carry the Linux system, so small chips generally use a real-time opera...
