Preferably, further comprising the steps of before the document analysis step: that nondocument is converted to document files.

Most of file of the prior art is not a document file format, as html format, DBF form etc., because the limitation of UNIX/LINUX character terminal for the file that is not document file format, need be carried out format conversion.The method of described file layout conversion can adopt any conversion method of the prior art, for example, imports the content of nondocument form based on document file format; Perhaps, directly the extension name of nondocument is changed into the extension name (as .doc is directly changed to .txt) of document files; Perhaps, use software to change (as the READBOOK tool software) etc., the present invention does not limit described conversion method, those skilled in the art as required or experience select for use and get final product.

Preferably, described nondocument is converted to document files after, can also according to the line width that presets and row is high carry out paging again or arrangement, in order to when showing, to offer the friendly interface that meets user's request to content corresponding.

Preferably, in described transfer process, for the form in the nondocument, can be converted into character list, for example, with " | " and "+", the col width that meets former form, the character list that row is high formed in character such as "-" document.A kind of character representation intention as shown in Figure 2.And, for the picture file in the nondocument, in being converted to the process of document files, owing to general UNIX/LINUX character terminal does not show, so should remove.Those skilled in the art can also set up other various transformation rules as required on their own, for example, the video file in the removal nondocument, audio file etc., the present invention does not need this to limit.

If document files has had corresponding index information, then directly obtain this index information, with the index information of this index information as the document file; If document files does not have corresponding index information, perhaps, there are inconsistent situation in this index information and file, then document files are resolved, and generate the index information of described document files.

Specifically, the process of described generation index information is: by the heading message in the analytical documentation file, and set up corresponding relation between the content of heading message and document files.For example, suppose that the pairing page number of title " preface " is 4, then index information is a preface---the 4th page; Perhaps, suppose that the pairing page number of title " preface " is 22, capable number is 20, and then index information is a preface---the 22nd page, and the 20th page.Described heading message obtains after can being scanned byte by the UNIX/LINUX character terminal.For example, by scanning certain document files, the heading message that obtains file is " preface ", " basic theory ", " specific implementation " and " case detailed annotation " etc.Certainly, described heading message also can be the initial speech of paragraph, perhaps, keyword etc., it all is feasible that those skilled in the art are provided with any heading message, the present invention does not need this to limit.

Preferably, described index information can also comprise page setup information, for example, it is 80 bytes that pagewidth is set, and page height is 22 row, document Time Created, the index upgrade time, and document size etc., those skilled in the art as required or any setting of experience all be feasible, the present invention does not need this to limit.

The user selects for a plurality of files for convenience, in practice, can pass through the menu displaying heading message, described menu can adopt any method of the prior art to generate by those skilled in the art, for example, write editmenu with shell, in programming process, menu-driven interface is handled as two-dimentional form, the content of drop-down menu and the subroutine title called are left in respectively in these two bivariate tables, by reading of his-and-hers watches, realized that the control cursor moves, the purpose of choice menus content and call subroutine.Certainly, it also is feasible that those skilled in the art adopt other menu generating method, and the present invention does not limit this.

Preferably, described index information can comprise multiple index information, in this case, described heading message can comprise the heading message of all document files, can also comprise a plurality of heading messages in the single document files, in this case, thestep 102 of described displaying heading message can comprise following substep:

Substep B1, other heading message of the displaying first order;

Substep B2, the heading message of selecting according to the user are showed other heading message of next stage.

In practice, described substep B2 can carry out according to the actual conditions circulation.

For making those skilled in the art understand the present invention better, below by way of example the embodiment of the invention is elaborated.

For example: one, preparation process:

By a plurality of document files are resolved, the heading message that generates a plurality of files is:

1, this collection (The Hound of Baskervilles) of detecting of Fu Er evil spirit;

2, this collection of detecting of Fu Er evil spirit (four signatures);

3, this collection of detecting (research of blood word) of Fu Er evil spirit;

4, Swordman;

…

Also comprise heading message in the described index information " 2, this collection of detecting of Fu Er evil spirit (four sign) ":

One: the research of deduction;

Two: the statement of merit;

Three: seek answer;

Four: bareheaded people's story;

…

Corresponding relation between described heading message and the content is:

One: the research of deduction--------------the 4th page, eighth row;

Two: the statement of merit----------------the 122nd page, the 20th row;

Three: seek answer------------------the 304th page, the 12nd row;

Four: bareheaded people's story--------------the 514th page, the 6th row;

Five: the tragic incident of cherry natural pond villa------------the 646th page, the 16th row;

Six: Holmes judges----------the 871st page, the 14th goes;

Seven: the interlude of wooden barrel----------------the 999th page, the 22nd row;

…

Two, step display:

Show other heading message of the first order, as shown in Figure 3;
