Description
Technical field
The application relates to computer systems technology field, particularly the method for information sifting and device in a kind of linux system.
Background technology
Linux as one stable and efficiently computer operating system be widely used always.There is very many fill orders in linux system itself, application software under this system and application program are also run based on fill order mostly, these fill orders have abundant parameter and combine available, therefore, can realize various powerful function by fill order.
But, when utilizing these fill orders to carry out information sifting, often have the following disadvantages:
1, fill order is too many, and the spelling title of the quantity of parameters especially in fill order, usage form, array mode and corresponding function etc. are all very numerous and diverse, and user is difficult to all memories and skillfully uses.Particularly for the vast user getting used to the operation of Windows graphical interfacesization, not easy to operate especially, thus cause the power of application software to make full use of;
2, software existing capability is not enough, such as: fill order is only just performed usually after user initiatively input, and the object of process is often more single;
3, software function is generally in order to the particular demands meeting user is developed, and therefore, application surface relative narrower, in the process that user uses in reality, often needs many moneys software to cooperatively interact a certain work; Or, also have some function items compare shortcoming or have deviation with the individual demand of user, in the process that user uses in reality, need to be replaced by some function items in other software.
In order to overcome above deficiency, prior art has following two kinds of processing modes usually:
1, the source code of original software systems is directly revised.But which is only applicable to the software of increasing income, need secondary development personnel to have enough abilities carefully to study carefully original source code, understand fully the system architecture of software, data structure, operation flow, code logic, functions of modules, interface parameters etc., even carefully all need to know its function to every line code.This mode workload is large, and the cycle is long, and risk is high, after particularly revising core source code, cause existing function to occur mistake or fluctuation of service possibly, after manufacturer's standardized product upgrading, directly can not carry out covering upgrading, needs are reintegrated, and this situation will be catastrophic;
2, the script utilizing software itself to provide or external DLL (dynamic link library) carry out secondary development.But which is only applicable to the software that those provide script or external interface, support secondary development, original software can be regarded as the development kit that encapsulates some application function implementation procedure, need secondary development personnel to be familiar with the logic function, service condition, parameter meaning, mutual relationship etc. of associated script language or interface function.Whether this kind of mode be feasible depends on whether original software is supported script or whether provide external interface, due to the difference of script or interface language type, data platform, data layout, communications protocol etc., this secondary development mode makes each software collaboration work there is certain difficulty for the function integrating multiple existing software.
As can be seen here, when screening the information in linux system, all there is the problem of different aspects in these processing modes above-mentioned.For these problems above-mentioned, at present effective solution is not yet proposed.
Above it should be noted that, just conveniently to the technical scheme of the application, clear, complete explanation is carried out to the introduction of technical background, and facilitate the understanding of those skilled in the art to set forth.Only can not think that technique scheme is conventionally known to one of skill in the art because these schemes have carried out setting forth in the background technology part of the application.

Embodiment
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all should belong to the scope of the application's protection.
The process flow diagram of the method for information sifting in a kind of linux system that Fig. 1 provides for the embodiment of the present application.Although hereafter describe flow process to comprise the multiple operations occurred with particular order, but should have a clear understanding of, these processes can comprise more or less operation, and these operations can sequentially perform or executed in parallel (such as using parallel processor or multi-thread environment).As shown in Figure 1, described method comprises:
S1: restrictive condition is set to visual button, and according to the type of described restrictive condition, the fill order of predetermined number is associated on described restrictive condition.
In linux system, fill order often has a lot, remembers these fill orders to user, and correctly inputs these fill orders, often there is a lot of difficulty.In the embodiment of the present application, user can be compared the restrictive condition of easy understand to be associated with the fill order in linux system relation, like this when user assigns operational order, some restrictive conditions can be disassembled out from operational order, linux system can according to the incidence relation between the restrictive condition set up in advance and fill order, the fill order that Automatically invoked is associated with the restrictive condition in the operational order of user, so just can realize the operational order of user's input easily.Particularly, by the storage mode of key-value, using restrictive condition as key, the fill order relevant to this restrictive condition can be stored as value, such linux system can by the restrictive condition of input, and fast query is to the fill order corresponding with this restrictive condition.
In the application one preferred embodiment, graphical user interface (GraphicalUserInterface can be utilized, GUI) restrictive condition is set to visual button by instrument, and according to the type of described restrictive condition, the fill order of predetermined number is associated on described restrictive condition.Particularly, can adopt the developing instrument Qt of GUI that various restrictive condition is set to visual button, user can be made like this can to assign operational order to linux system more easily.Such as, the operational order of user can be " after searching on June 5th, 2015 the lower document upgraded of sound code file folder ", in this operational order, two restrictive conditions can be disassembled out, first restrictive condition can be " searching the document under sound code file folder ", and second restrictive condition can be " updated after 5 days June in 2015 ".In the embodiment of the present application, can adopt Qt that these two restrictive conditions are set to visual button, such as first button is " SearchCommittedFiles ", user is after this button of click, follow-up dialog box can be ejected, second button " LimittheTime " can be set in this dialog box.Like this, by two buttons, such instruction that user just can assign to linux system " searching the lower document upgraded of sound code file folder after on June 5th, 2015 ".
After restrictive condition is set to visual button, the embodiment of the present application can according to the type of restrictive condition, for it associates corresponding fill order.Such as, for " SearchCommittedFiles " this restrictive condition, just this system call function of " system " in Linux can be associated with it as a fill order, popen (" CVSlog ") this fill order calling " CVSlog " can also be associated with it in addition.
Like this, the embodiment of the present application just can provide a visual graphical interfaces for user, facilitates user to assign various operational order to linux system.
S2: in response to the first restrictive condition in operational order, calls the fill order be associated with described first restrictive condition.
As described in step S1, user is after assigning operational order to linux system, and this operational order can be disassembled as some restrictive conditions by linux system.The process of described tear down operations instruction can be that designer pre-sets.Such as the operational order of similar " after searching on June 5th, 2015 the lower document upgraded of sound code file folder ", designer can utilize GUI developing instrument to be disassembled as " SearchCommittedFiles " and " LimittheTime " these two restrictive conditions.When user clicks " SearchCommittedFiles " this restrictive condition, linux system just can the fill order that is associated with this restrictive condition of Automatically invoked, such as " system " call function and popen (" CVSlog ") call function.Like this, by the first restrictive condition in operation response instruction, linux system just can associated the first fill order of Automatically invoked.Here it should be noted that, described first fill order can comprise one or more fill order, and described fill order can be (SuSE) Linux OS, and may also be is Linux application software, and the application does not limit this.
S3: the fill order be associated with described first restrictive condition according to calling obtains first information collection.
After linux system calls the first fill order be associated with the first restrictive condition, by performing this first fill order, just can get first information collection.Described first information collection is corresponding with described first restrictive condition.Such as, for " SearchCommittedFiles " this restrictive condition, linux system just can by popen (" CVSlog be for the sound code file folder pathname of search ", " r ") this function is as fill order, search the document under sound code file folder path, the document just can as the first information collection corresponding with " SearchCommittedFiles " this restrictive condition.But, in some cases, can not get by a restrictive condition information set that user wishes, or the information of the information set got is more, needs to screen it.Therefore, the embodiment of the present application is further comprising the steps of:
S4: judge whether described first information collection meets pre-conditioned, if do not meet, then in response to the second restrictive condition in described operational order, and calls the fill order be associated with described second restrictive condition.
Describedly judge whether first information collection meets pre-conditioned process, the information content can concentrated by scanning the described first information has come.Particularly, the embodiment of the present application can pre-set the threshold value of information content, and being less than or equal to this threshold value just can for described pre-conditioned.After getting first information collection, linux system can scan the quantity of this first information collection, when the quantity scanned is less than or equal to this threshold value, just first information collection can be exported as net result; When the quantity scanned is greater than this threshold value, just judge that described first information collection does not meet pre-conditioned, so in response to the second restrictive condition in described operational order and according to described restrictive condition and exectorial incidence relation, the second fill order be associated with described second restrictive condition can be called.Such as " after searching on June 5th, 2015 the lower document upgraded of sound code file folder " this operational order, described second restrictive condition can be " after 5 days June in 2015 " this time restriction.Correspond to this time restriction, designer can pre-set button " LimittheTime ", and user can be allowed to arrange the time point of restriction.Now the second restrictive condition can be regarded as the screening conditions to first information collection, thus using the fill order relevant to screening as the second fill order, and can be associated with the second restrictive condition.Such as, the function of this for QRegExp regular expression class can associate as the second fill order with the second restrictive condition by the embodiment of the present application.So linux system just in response to the second restrictive condition, can call the second fill order associated with it.Same, described second fill order can comprise one or more fill order, and described fill order can be (SuSE) Linux OS, and may also be is Linux application software, and the application does not limit this.
S5: utilize the fill order be associated with described second restrictive condition called to screen described first information collection, obtains the second information set after screening.
After calling the second fill order be associated with described second restrictive condition, described second fill order just can be utilized to screen described first information collection, obtain the second information set after screening.In the application one preferred embodiment, this step can be completed by following two steps:
S51: generate regular expression according to described second restrictive condition.
Regular expression can use single character string to describe, mate a series of character string meeting certain syntactic rule.Suppose there is a file test.txt and comprise following a few row content:
heisarat
heisinarut
thefoodisRotten
Ilikerootbeer
Now, if the character string of a r then any one character then t again will be filtered out from this test file, so just regular expression can be generated: r.t.Then grep order just can be used to test this regular expression, and grep order can use regular expression to go to attempt the every a line in coupling appointment test file, and all row that will have at least place's matching expression show.This order can be grepr.ttest.txt, and so rat and rut in test file can mate out by this order, but but can not mate the Rot in Rotten, because regular expression is case sensitive.Want to mate upper case and lower case letter simultaneously, metacharacter between character area should be used.Regular expression [Rr] can mate R and r simultaneously.So, want r then any one character then t again of coupling one capitalization or small letter, this regular expression will be generated: [Rr] .t.
Particularly, the embodiment of the present application can utilize character recognition technologies, from the second restrictive condition of user's input, automatically generate regular expression.Such as, second restrictive condition of user is " document searching r then any one character then t again with a capitalization or small letter in sound code file folder ", so utilize character recognition technologies to identify this second restrictive condition, just automatically can generate the regular expression that [Rr] .t is such.
S52: utilize the fill order be associated with described second restrictive condition called to scan every bar information that the described first information is concentrated, filter out the information meeting described regular expression, and the information meeting described regular expression is defined as the second information set after screening.
After generating the regular expression corresponding with the second restrictive condition in step s 51, described second fill order can be utilized to scan every bar information that the described first information is concentrated, filter out the information meeting described regular expression, and the information meeting described regular expression is defined as the second information set after screening.Particularly, the embodiment of the present application can call regular expression class function QRegExp, scans every bar information that the described first information is concentrated.In the embodiment of the present application, suppose that the first information integrates as the lower document of sound code file folder, so utilize the QRegExp function scanning first information to concentrate the false code of the update time of document can be as described below:
Wherein, year, month, day, hour, min, sec are year, month, day, hour, min, the second of document update time respectively, if the regular expression of this time and generation matches, then record the document.
Like this, by utilizing the second fill order to the scanning of first information collection, just can filter out the information meeting described regular expression, thus the information meeting described regular expression can be defined as the second information set after screening.
Certainly, if this second information set does not still meet pre-conditioned, so can continue to generate new regular expression according to the 3rd restrictive condition, and utilize the 3rd fill order be associated with the 3rd restrictive condition to scan the second information set, filter out the information meeting new regular expression, thus the quantity of information concentrated message can be reduced further, until meet pre-conditioned.
It should be noted that, the matching process of the process of screening more complicated is often carried out owing to utilizing regular expression, the embodiment of the present application is in order to improve the efficiency of matching process, utilizing described second fill order, described first information collection is screened, before obtaining the second information set after screening, described method can also comprise:
Utilize pipe technology, described first information collection is directed in memory block.Like this, just can, in described memory block, utilize the fill order be associated with described second restrictive condition called to screen described first information collection, obtain the second information set after screening.
Particularly, pipe technology is a kind of communication mode in linux system, the output of a program can be directly connected to the input of another program.Here, can using the output of described first information collection as a program, using the input of memory block as another degree, thus can first information collection larger for data volume be directed in memory block, and the screening process of carrying out in memory block first information collection, the efficiency of matching process can be improved like this.
In another preferred embodiment of the application, before screening first information collection, the embodiment of the present application can also comprise:
According to the fill order be associated with described second restrictive condition called to the demand of data layout, format conversion is carried out to every bar information that the described first information is concentrated.
Because the input data in different application required by fill order often exist different-format, the embodiment of the present application is in order to be used described first information collection by other call functions better, therefore can be the required form of fill order be associated with described second restrictive condition to the format conversion of every bar information that the described first information is concentrated, enconv or iconv instruction can be adopted particularly, a formatted data is converted to the data of another form, it can be such as the file of UTF-8 coding by the file transform that GBK encodes, thus the fill order be associated with described second restrictive condition called can be utilized to screen the first information collection after format conversion, the docking between different call function can be facilitated like this.
The embodiment of the present application also provides the device of information sifting in a kind of linux system.The functional block diagram of the device of information sifting in a kind of linux system that Fig. 2 provides for the embodiment of the present application.As shown in Figure 2, described device can comprise:
