By two installation iso CD carries in some operating system；
Above-mentioned CD is compared, compares catalogue where the file of CD first, i.e., all texts in each CD
Part is all traversed, then more all CDs, carries out smartphone and similarity analysis；
Then compare rpm packet content, the content in the rpm packet for including in each CD is compared, carry out intelligent receipts
Collection and similarity analysis.
The process of catalogue where comparing optical file are as follows: the multiple CDs of carry first, then in each CD of order traversal
All Files directory address；The address where file directory in all CDs of intellectual analysis；It finds in each CD
Main comparable file and be compared.
The detailed process of catalogue where traversing the file of CD are as follows:
It is divided into two parts when traversal, first part is subdirectory, and sub- subdirectory and sub- Ziwen are further divided under subdirectory
Part ...；
Second part is file, and file no longer divides, that is, encounters file when traversing and be recorded, encounter catalogue and traverse mesh
File under record；
When traversal when encounter be empty list when, be just deleted, do not note down, at the same using each file big small tenon
Remember path file, data preparation is at document；
The content similarities and differences in document that last all traversal CDs of intellectual analysis are organized into.
The intellectual analysis process of the document content similarities and differences are as follows:
Select the root name of first file name traversed in the above-mentioned document being organized into, i.e. the first of file name
A field is as intellectual analysis target, if without corresponding text under the same directory in the document that second CD is organized into
Part, then label is no file after file path in first document, does not mark any file in second document；
If finding a corresponding file under the same directory in the document that second CD is organized into, and this file
Identical with the file name of first file, then marking after file path in first document is same, second
This document is labeled as pass in a document；If not exactly the same, perform the next step；
If finding a corresponding file under the same directory in the document that second CD is organized into, this file with
First file name is not exactly the same, then relatively more secondary file name, i.e. the first character section of file name, if identical,
Compare time time file name, i.e. the second of file name field compares, if identical, compares time time time file name, i.e.,
The third field ... of file name until comparing field initial character for number, then in the first document after file path together
Labeled as no same version, while in second document, this document is labeled as no same version；
If the name field initial character ratio of the file in the title of the file found in the second document and the first document
Compared with when, just different before encountering number, then it is 2 no file that the file name in the path is marked in the first document of label,
Comparison document in second document does not make marks；
It is compared according to the file in the first document copy copy always, has traversed all files, after the completion of traversal,
List label result；
1 no file is labeled as if the file of unmarked pass in the second document copy copy；
It is file to label in two parts of copy copies, the same, no same version, 1 no file
File is arranged, and finds comparable file to be same version labeled as label in the copy copy of the first document
File.
Compare the detailed process of rpm packet content are as follows: opened in advance to rpm packet, record the file pre-placing mesh in rpm packet
Record, i.e., select the file found in above-mentioned steps, if suffix is not rpm packet, individually list；If it is rpm packet,
Rpm packet described in the copy copy of the first document is opened, rpm packet described in the copy copy of the second document is opened in comparison,
And compare the difference opened in advance twice, result is listed after record.
A kind of method of relatively Linux system CD iso similarities and differences of the invention, has the advantage that
A kind of method of relatively Linux system CD iso similarities and differences of the invention, passes through the angle changing rate of mirror image internal file

Specific embodiment
The present invention is further explained in the light of specific embodiments.
The present invention provides a kind of method of relatively Linux system CD iso similarities and differences, realizes process are as follows:
The comparison carried out mainly for the file in Linux system CD is compared including catalogue where file,
The contents such as comparison two parts of rpm packet content.This is clearly demarcated to propose similarity intelligent analysis process, come detect different types of optical disks it
Between or same class CD different editions between the similarities and differences, thus to using different Linux system CDs to build operating system
The similarities and differences, the reference frame of a side is provided.
Catalogue where two parts content is file is relatively that the All Files in CD is needed to be traversed, and comparable
CD carry out multi-level ratio and convert, and carry out smartphone and similarity analysis；The comparison of rpm packet content, is in CD
The rpm packet for including in carry out smartphone and similarity analysis comprising content and comparable CD.
Based on above-mentioned steps, specific implementation process of the invention are as follows:
Carry CD 1 and CD 2；Traverse CD 1 in All Files directory address；It traverses all in CD 2
File directory address；The address where file directory in intellectual analysis CD 1 and CD 2；Find CD 1 and CD 2
In main comparable file；Rpm packet is opened in advance, records the file pre-placing catalogue in rpm packet；Summarized results.
In more detail, above-mentioned steps are as follows:
Step 1, installation iso CD carry in certain operating system, carry is carried out to the two systems CD to be compared,
System CD 1, system CD 2.
Step 2, the file and catalogue for traversing CD 1 are divided into two parts, first part is subdirectory, subdirectory when traversal
Under be further divided into sub- subdirectory and sub- subfile ..., second part is file, and file no longer divides, i.e.,；File is encountered when traversal
It is recorded, encounters the file under catalogue i.e. traversing directories.If it is empty list, that is, it is deleted, is not recorded.Simultaneously using each
The size path label file of a file, data preparation is at document 1.
Step 3, with the operation in step 2, traverse the file and catalogue of CD 2, data preparation is at document 2.
The similarities and differences of content in step 4, intellectual analysis document 1 and document 2: it is made reference with the copy copy of document 1 and document 2
Pass is marked in document, the file detected in the copy copy of document 1.
Select the root name (the first character section of file name) of traverse in document 1 first file name as intelligence
Target can be analyzed, if label is after file path in document 1 without corresponding file under the same directory in document 2
No file does not mark any file in document 2.
If finding a corresponding file under the same directory in document 2, and the text of this file and first file
Part title is identical, then label is same after file path in document 1, and this document is labeled as pass in document 2；Such as
Fruit is not exactly the same, then performs the next step.
If finding a corresponding file under the same directory in document 2, this file and first file name are not
Identical, then relatively more secondary file name (the first character section of file name) compares time time file name if identical
(file name the and a field) compares, if identical, relatively time time time file name (the third word of file name
Section) ... until comparing field initial character together for number (only digital difference), then marked after file path in document 1
For no same version, respective version number can be listed respectively if needed, while this document is labeled as no in document 2
same version。
If the title of the file found in document 2 is compared with the name field initial character of the file in document 1,
Encounter just different before number, then it is 2 no file that the file name in the path is marked in marking document 1, the ratio in document 2
It does not make marks compared with file.
The file in copy is copied according to document 1 always to be compared, traverse all files, after the completion of traversal, is arranged
Result is marked out.
File mark as document 2 copies unmarked pass in copy is 1 no file.
It is file to label in two parts of copy copies, the same, no same version, 1 no file
File is arranged.
Step 5 finds comparable file to be same version labeled as label in the copy copy of document 1
File, this document are mostly rpm packet.
Step 6 selects the file found in step 5, if suffix is not rpm packet, individually lists；If it is
Rpm packet opens rpm packet described in the copy copy of document 1, such as A.1.rpm A.rpm then executes rpm-qpl, and comparison is beaten
Rpm packet described in the copy copy of document 2 is opened, such as rpm-qpl is A.2.rpm, and compare the difference opened in advance twice, remembered
Record is in rpm packet is opened relatively in advance.
The data of step 7, aggregation step 4 and step 6, intelligently list correlated results.
By the above method, two Linux system CD iso can be quickly provided, two linux light can be quickly summed up
The difference and something in common of disk.
