Problems solved by technology

[0002] With the development of computer technology, the built-in system version of CD-ROM products is also constantly changing. For example, in the Centos6.x operating system version, each version has different changes. The later the version, the more content is added. Now Centos 7.0 It can also be compared with the Centos7.1 image file, but the staff cannot quickly and intuitively discover the similarities and differences between all CD product systems, which makes the staff unable to use it in a timely and rapid manner based on its improvement, and the use efficiency is not high. The difference between image files between CentOS6.x or Centos7.x, the present invention provides a method for comparing the similarities and differences of linux system disc iso

Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific examples.

[0026] The present invention provides a method for comparing the similarities and differences of Linux system CD ISOs, the realization process of which is as follows:

[0027] Mainly for the comparison of files in the Linux system CD, including the comparison of the directory where the files are located, the comparison of the two parts of the rpm package content, etc. Benming proposed an intelligent similarity analysis algorithm to detect the similarities and differences between different types of CDs or different versions of the same type of CDs, so as to provide a side reference for the similarities and differences of using different Linux system CDs to build operating systems.

[0028] The content of the two parts is the comparison of the directory where the files are located. It is necessary to traverse all the files in the CD, perform multi-level comparisons with comparab...

Abstract

The invention discloses a method to compare iso similarities and differences of linux system discs. Detailed realization process is as follows. Two installation iso discs are mounted on an operating system and comparison is carried out aiming at the above-mentioned discs. Firstly, directories of all files in each disc are compared, i.e., all files in each disc are traversed and two discs are compared for intelligent collection and similarity analysis. Secondly, contents of rpm packages are compared: comparison of contents of rpm packages from each disc is carried out for intelligent collection and similarity analysis. Compared with the existing technology of comparing iso similarities and differences of linux system discs, differences among small versions or large versions of Centos from the aspect of image internal files are compared and analyzed, which facilitates the user to use the discs more quickly and accurately according to the contents of each version, improves the efficiency of the use of disc products, and facilitates the user to choose different system versions for installation according to their own needs, the method is practical and liable to promote.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for comparing the similarities and differences of Linux system CD ISOs with strong practicability. Background technique [0002] With the development of computer technology, the built-in system version of CD-ROM products is also constantly changing. For example, in the Centos6.x operating system version, each version has different changes. The later the version, the more content is added. Now Centos 7.0 It can also be compared with the Centos7.1 image file, but the staff cannot quickly and intuitively discover the similarities and differences between all CD product systems, which makes the staff unable to use it in a timely and rapid manner based on its improvement, and the use efficiency is not high. For the difference in image files between CentOS6.x or Centos7.x, the present invention provides a method for comparing the similarities and differences of Linux system C...
