Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a directory splitting method is provided, where this embodiment is applied to a terminal to illustrate the method, and it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step S101, a current du data list composed of du data to be subjected to catalog separation is obtained, and absolute path information corresponding to each du data in the current du data list is obtained; du data is obtained by executing a command for checking the disk usage.
The du data to be subjected to directory separation refers to du data required to perform directory separation operation, and the du data may be du data obtained after a user initiates a du command, that is, a command for checking a disc service condition, and not subjected to directory separation yet, or remaining du data required to continue directory separation after directory separation has been performed. The current du data list refers to a data list composed of the du data to be catalogued and separated, and the absolute path information is the complete path information corresponding to each du data in the list.
In this embodiment, after executing the du command for checking the usage situation of the disc, the terminal may obtain du data that is currently required to be subjected to directory separation, where the du data may form a current du data list, and in the du data, complete path information of each file or directory obtained by traversing the du command may also be stored, and the terminal may use the complete path information as absolute path information, thereby obtaining absolute path information of each du data in the current du data list.
Step S102, obtaining a path information inclusion relation between first absolute path information and second absolute path information associated with current du data aiming at any current du data in a current du data list; the first absolute path information is absolute path information corresponding to the last du data of the current du data in the current du data list, and the second absolute path information is absolute path information corresponding to the current du data.
The current du data refers to any row of du data in the current du data list, the first absolute path information associated with the current du data refers to absolute path information corresponding to the last du data of the current du data, and the second absolute path information associated with the current du data refers to absolute path information corresponding to the current du data.
After obtaining the current du data list, the terminal may further take each du data in the current du data list as current du data one by one, and obtain first absolute path information and second absolute path information associated with each current du data respectively, so as to determine whether the first absolute path information associated with each current du data includes the second absolute path information, and further obtain a path information inclusion relationship corresponding to each current du data.
Step S103, if the second absolute path information is not contained in the first absolute path information of the containing relation representation, writing the current du data into a first sub du data list corresponding to the current du data list;
step S104, obtaining the catalog separation round corresponding to the current du data list, and taking the first sub-du data list as a separation catalog list matched with the separation catalog level under the condition that the catalog separation round reaches the target separation round matched with the preset separation catalog level.
The first sub du data list is a data list formed by separating out part of du data from the current du data list, the directory separation round refers to the round of performing directory separation currently, the separated directory level refers to a preset level of the directory to be separated, and if files representing a first-level directory need to be separated, the separated directory level can be a first-level directory. If a secondary directory containing only files is to be split, the split directory hierarchy may be secondary, and so on. The target separation round refers to a catalog separation round matched with a preset catalog level, if a primary catalog needs to be separated, the catalog separation round can be set to 1, and if a secondary catalog needs to be separated, the catalog separation round can be set to 2.
In this embodiment, since du data is traversed according to depth, the deeper the hierarchy, the more forward, then taking the directory splitting round as an example, if absolute path information corresponding to the last du data of a certain current du data, that is, the first absolute path information associated with the du data, and if absolute path information of the current du data, that is, the second absolute path information associated with the du data, is included, it is stated that the directory corresponding to the last du data is inside the directory corresponding to the current du data, and the current du data is the upper directory of the last du data, then the directory corresponding to the current du data is not necessarily a file characterizing the first-level directory. And only the second absolute path information is not contained in the containing relation representation first absolute path information, and the relation between the current du data and the last du data does not exist between the upper and lower levels of the directory, in this case, it can be indicated that the current du data corresponds to the file representing the primary directory, so by writing the current du data into the first sub-du data list, all the du data stored in the first sub-du data list can be used for representing the file representing the primary directory, therefore, in this way, if a user needs to separate the file representing the primary directory, the target separation round with matched levels of the separation directory can be set to be 1, and then the terminal only needs to execute one directory separation operation, thereby obtaining the first sub-du data list serving as the separated file list.
Similarly, if the secondary catalog is required to be separated, since the file representing the primary catalog is already separated when the current du data list is separated for the first time, if the du data separation is performed again, that is, the processes from step S102 to step S103 are performed again, the secondary catalog is the catalog with the deepest hierarchy in the remaining du data, so that the secondary catalog can be separated from other high-level catalogs, such as the tertiary catalog, by this way, the user only needs to set the target separation round to be 2, and the terminal only needs to perform 2 catalog separation operations, thereby realizing the separation of the secondary catalog.
In the catalog separation method, the current du data list consisting of du data to be catalog-separated is obtained, and absolute path information corresponding to each du data in the current du data list is obtained; the du data is obtained by executing a command for checking the use condition of the disk; for any one current du data in the current du data list, acquiring a path information inclusion relation between first absolute path information and second absolute path information associated with the current du data; the first absolute path information is absolute path information corresponding to the last du data of the current du data in the current du data list, and the second absolute path information is absolute path information corresponding to the current du data; if the second absolute path information is not contained in the first absolute path information of the containing relation representation, writing the current du data into a first sub du data list corresponding to the current du data list; and acquiring a catalog separation round corresponding to the current du data list, and taking the first sub du data list as a separation catalog list matched with the separation catalog level under the condition that the catalog separation round reaches a preset target separation round matched with the separation catalog level. According to the method and the device, the current du data list consisting of the du data to be subjected to catalog separation is constructed, absolute path information corresponding to each du data of the list is obtained, absolute paths of any one current du data in the list are compared by using the absolute path information, and the containing relation between the absolute paths corresponding to the last du data of the du data is used, so that the current du data can be written into the first sub-du data list under the condition that the absolute paths corresponding to the last du data do not contain the absolute paths of the current du data, and when catalog separation turns meet the separation catalog level, the separated first sub-du data list is used as the separation catalog list, and therefore catalog separation is achieved.
In an exemplary embodiment, as shown in fig. 2, step S102 may further include:
step S201, a first pointer value of a first pointer associated with the current du data is obtained, and second absolute path information is assigned to a second pointer; the first pointer value is used to store first absolute path information.
In this embodiment, the first absolute path information and the second absolute path information associated with the current du data may be stored by two pointers, where the first pointer is a pointer for storing the first absolute path information, for example, a previous pointer, and the second pointer may be a pointer for storing the second absolute path information, for example, a current pointer.
Specifically, the terminal may obtain the path information inclusion relationship between the first absolute path information and the second absolute path information associated with the current du data by setting two pointers, where the first pointer value may store the first absolute path information of the current du data in advance, and then, after obtaining the absolute path information corresponding to the current du data, that is, the associated second absolute path information, the terminal may assign the second absolute path information to the second pointer.
Step S202, obtaining a path information inclusion relationship according to the pointer value inclusion relationship between the first pointer value and the second pointer value of the second pointer.
Because the first pointer value already stores the first absolute path information associated with the current du data at this time, and the pointer value of the second pointer, namely the second pointer value, stores the second absolute path information associated with the current du data, the path information inclusion relationship between the first absolute path information and the second absolute path information can be represented by the inclusion association between the first pointer value and the second pointer value.
In this embodiment, the terminal may store the first absolute path information and the second absolute path information through the first pointer and the second pointer, that is, through the two pointers, the obtaining of the address information inclusion relationship is achieved, so that the obtaining efficiency of the address information inclusion relationship may be further improved.
Further, after step S202, the method may further include: assigning the second pointer value to the first pointer to obtain an updated first pointer; the updated first pointer is used for storing first absolute path information associated with the next du data of the current du data in the current du data list.
After the address information containing relation of the current du data is obtained, because the absolute path information corresponding to the last du data of the current du data is stored in the current first pointer value, if the next du data of the current du data needs to be obtained, the containing relation of the path information can also be obtained by using the first pointer and the second pointer, the terminal needs to assign the current second pointer value to the first pointer to obtain the updated first pointer, the absolute path information corresponding to the current du data can be stored in the first pointer value of the updated first pointer at this time, and when the path information containing relation of the next du data of the current du data is obtained, because the first pointer value is the absolute path information of the current du data at this time, the absolute path information corresponding to the next du data can be obtained for the next du data of the current du data, the absolute path information corresponding to the next du data is represented at this time, and the absolute path information corresponding to the next du data can be updated by using the second pointer, and the absolute path information corresponding to the second pointer can be realized by using the updated absolute path information corresponding to the second pointer value.
In this embodiment, after the acquisition of the path information containing relationship corresponding to the current du data is completed, the second pointer value may be assigned to the first pointer, so that the path information containing relationship corresponding to all du data in all the current du data lists is obtained by using the two pointers, and the acquisition convenience of the path information containing relationship is further improved.
In addition, in the case where the current du data is the first du data in the current du data list, before step S201, the method may further include: the first pointer value of the first pointer and the second pointer value of the second pointer are set to null values.
If the current du data is the first du data in the current du data list, that is, if the first data in the current du data list has no pointer value, then in order to enable the directory separation process to be smoothly executed, the terminal may perform null value processing on the pointer values of the first pointer and the second pointer, that is, set the first pointer value and the second pointer value to null values.
In this embodiment, if the current du data is the first du data in the current du data list, the terminal may further set the first pointer value and the second pointer value to null values, so that smooth execution of directory separation may be ensured, and thus the running stability of directory separation may be further improved.
In one embodiment, after step S102, the method may further include: if the path information contains the relation representation first absolute path information and contains second absolute path information, writing the current du data into a second sub du data list corresponding to the current du data list; after step S104, the method may further include: in the case that the catalog separation round does not reach the target separation round, the second sub du data list is taken as a new current du data list, and the step S101 is executed back until the catalog separation round reaches the target separation round.
The second du data list refers to a du data list formed by remaining du data after the first du data list is separated from the current du data list, and because the du data included in the first du data list is du data that does not include the second absolute path information in the associated first absolute path information, the du data forming the second du data list is du data that includes the second absolute path information in the associated first absolute path information.
Specifically, if the path information includes the relation characterizing the first absolute path information and the second absolute path information is included in the first absolute path information, the terminal may write the current du data into the second sub-du data list. After completing the catalog separation of all the du data in the current du data list, if the catalog separation round does not reach the target separation round, the terminal may return to obtain the absolute path information again with the second sub-du data list as a new current du data list, and execute the step of implementing the catalog separation by using the inclusion relationship between the absolute path information until the catalog separation round reaches the target separation round.
For example, if the directory to be separated is a secondary directory, the preset separation directory level may be 2 levels, if the current directory separation round is 1 time, and the target separation round matched with the separation directory level is not reached, at this time, after the terminal completes the first directory separation to form the first sub-du data list and the second sub-du data list, the terminal may use the remaining second sub-du data list including the secondary directory and the du data of other high-level directories as a new current du data list, and execute the directory separation operation again, after completing the second directory separation again, because the separation directory level has been reached, the terminal may use the first sub-du data list obtained by the second separation as the finally separated secondary directory list.
In this embodiment, the terminal may further generate a second sub-du data list, and the second sub-du data list may be used as a new current du data list when the directory splitting round does not reach the target splitting round.

And then constructing a first sub-du data list, and writing the capacity information of the current du data into the first sub-du data list in addition to the current du data, so that in the formed separated directory list, the terminal can obtain the directory capacity corresponding to each du data.
Step S402, sorting all du data contained in the separated directory list according to directory capacity, and storing the pre-preset number of du data with the largest directory capacity in all du data contained in the separated directory list into a result path file;
step S403, the result path file is subjected to visual display processing.
After the catalog capacity of each du data in the separated catalog list is obtained, the du data in the separated catalog list can be sorted according to the catalog capacity, for example, the du data can be sorted according to the order of the catalog capacity from large to small, and the former preset number of du data with the largest catalog capacity in the du data can be stored in the result path file, for example, the first n du data with the largest capacity can be stored in the result path file, and visual display is performed, so that the user can quickly locate the catalog with larger occupied capacity, for example, locate the large file, the secondary catalog with larger capacity, and the like.
In this embodiment, the terminal may further implement screening of the large-capacity directory according to the directory capacity corresponding to each du data, and visually display the large-capacity directory, thereby further improving the intelligence of directory analysis.
In one embodiment, a method for statistical analysis of files and directories is also provided, which can extract du data of a user when storage is idle, then separate files, secondary directories including only files and high-level directories using an algorithm based on the du data, and locate large files and secondary directories including only files by a sorting algorithm.
