Abstract

PROBLEM TO BE SOLVED: To perform a path name reinput appropriately by providing a computer which produces a list of real existence file names corresponding to a false file name part and returns it to a request source when the file of a designated path does not exist. SOLUTION: A file request including a designated path is transferred from a terminal computer 4 to a remote server computer 6 through a local server computer 3. When a list producing part 24 receives notification to the effect that a request file does not exist from a deciding part 23, it examines up to what step an actually existing part is in a path name in a file transfer request while accessing a file 20 through a file accessing part 22. And, it produces a list of file names existing actually in a corresponding part of the false part. This list is transferred to the terminal computer 4 and a picking up part 17 picks up a file name of real existence from a real existence file list and displays it on a selection input possible displaying part 18.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system with a path name re-entry assisting function which is characterized in that it assists in re-entering a correct path name when a path name is erroneously entered in a tree-structured file system. And a recording medium.

[0002]

2. Description of the Related Art Generally, a computer file system has a tree structure (hierarchical structure), and its final file name (path name) is often very long. To read such a computer file, the operator must enter the long path name. However, in the conventional computer system, a path name is erroneously input, and as a result, an error always occurs unless the specified file exists.

Therefore, in order to prevent such an error from occurring, a path name must be checked in advance,
Must be entered correctly. However, since an error is caused by a typographical error of only one character in a long path name, it is difficult to determine which part of the input data is incorrect at the time of error.

If the examined path name itself is invalid, it is necessary to log in to the computer from which the file is to be read by some means and confirm the correct path name. is there.

[0005] Such a problem becomes particularly remarkable when reading a file from a remote computer. This is because, in the case of a remote computer via a network, for example, a file transfer request can be made as in a home page on the Internet, but the web server itself cannot be logged in, and it often takes time and effort to check the path name.

[0006]

As described above, in the conventional computer system, when there is a simple error in the designated path character string or when the directory is missing one step, etc.
"Specified file does not exist" error occurs.
That is, the conventional system is based on the assumption that the designated path character string is not erroneously designated one by one phrase, and does not consider at all that there is a high possibility that a human makes an erroneous input from the keyboard.

Further, the conventional computer system cannot cope with an ambiguous input based on ambiguous information such that the path name at least halfway is accurate but the final path name is not definitive. In that case, it simply returned an error indication.

The present invention has been made in consideration of such circumstances, and even when an input path name is incorrect or an indeterminate and ambiguous path name is input, the path name is not changed. It is an object of the present invention to provide a computer system with a path name re-entry assisting function and a recording medium that can flexibly provide an input response so that name re-entry can be appropriately performed.

[0009]

In order to solve the above-mentioned problems, the invention according to claim 1 comprises at least a first computer for managing a requested file and a second computer for requesting a file. It is composed.

[0010] First, the first computer uses the first computer.
File is requested from the computer. In the first calculator,
If the file of the designated path does not exist when the file transfer request is received, it is examined how far the designated path actually exists. Further, the first computer creates a list of existing file names corresponding to the incorrect file name portion, and returns this list to the requesting second computer in place of the request file.

The list is received by a second computer,
Part or all of the list is displayed. Therefore,
Even when the input path name is incorrect or when the input of the path name is uncertain and ambiguous, the path name can be properly re-input.

Next, in a second aspect of the present invention, in the first aspect of the present invention, if the directory of the specified path does not exist, the first computer actually exists in the specified path. A check is made and a list of the actual directory names corresponding to the invalid directory name is created.

Therefore, if not only the name of the final file but also the directory name in the middle is incorrect, the actual directory name is shown. In such a case, the path name can be properly and easily input again. It becomes possible. In addition,
By using the function of the present invention, for example, even if the entire specified path leading to the final file name is not known, it is possible to follow the target directory file by receiving the directory name list at an intermediate stage.

Next, a third aspect of the present invention is a recording medium storing a program for causing a computer to realize the first aspect of the present invention. The computer controlled by the program read from the recording medium functions as the first computer of the first aspect.

Next, a fourth aspect of the present invention is a recording medium storing a program for causing a computer to implement the second aspect of the present invention. The computer controlled by the program read from the recording medium functions as a first computer according to claim 2.

Next, a fifth aspect of the present invention is a recording medium storing a program for causing a computer to implement the first or second aspect of the present invention. The computer controlled by the program read from the recording medium functions as a second computer according to claim 1 or 2.

According to a sixth aspect of the present invention, in the invention according to the fifth aspect, the re-entry assisting means compares the erroneous input file name in the designated path with the actual file name in the list. The actual file name having a high degree of matching is displayed. Therefore, more accurate re-input assistance is performed.

[0018]

Embodiments of the present invention will be described below. (First Embodiment of the Invention) FIG. 1 is a block diagram showing a configuration example of a network system to which a computer system with a path name re-entry assisting function according to a first embodiment of the present invention is applied.

In this network system, a network A and a network B are connected via a router 1. The relationship between networks A and B is network A
A computer belonging to network B can request file transfer to a computer belonging to network B but cannot log in. Here, both networks A and B
Are connected via the router 1, but both may be connected via a public line, for example.

The network A is a LAN in which a local server computer 3 and a plurality of terminal computers 4 are connected to a data transmission path 2. The local server computer 3 includes a workstation and a large computer, receives various service requests from the terminal computer 4, and transfers a file transfer request belonging to another network to another network.

The terminal computer 4 comprises a personal computer and a workstation. On the other hand, the network B is a LAN in which a remote server computer 6 and a plurality of terminal computers 7 are connected to a data transmission path 5.
The remote server computer 6 and the terminal computer 7 are configured similarly to the local server computer 3 and the terminal computer 4,
The remote server computer 6 is connected with a storage device 8 for recording various files, and returns files and the like in response to a file transfer request from the network A.

Note that it is not possible to directly log in to a computer on another network between the two networks A and B. If a file on another network is used, the file is transferred to a computer on the other network. You need to make a request. In this embodiment, a case is considered in which a file managed by the remote server computer 6 is requested to be transferred from the terminal computer 4 of the network A via the local server computer 3.

FIG. 2 is a block diagram showing the relationship between a terminal computer and a local server computer on the network A and a remote server computer on the network B. As shown in the figure, the terminal computer 4 includes an input device 11 and a display device 12.
Is connected, and the input / output unit 13 as a GUI
And a file request sending unit 14 for requesting a file with the path name input from the input device 11, and a communication processing unit for performing communication processing such as sending this file request (also called a file transfer request) to the local server computer 3. 15, a file determination unit 16 for determining a reply file, a pickup unit 17, and a selectable input display unit 18 are provided.

The local server computer 3 is provided with a transfer daemon 19 for transferring a file request from the terminal computer 4 to the remote server computer 6 on the network B. The remote server computer 6 receives a file request from the terminal computer 4, searches for the corresponding file from the various files 20 in the storage device 8, and returns it.
A file access daemon 21 is provided that creates and returns a list of file names or directory names (existing file list) in the relevant directory when there is no corresponding file.

The file access daemon 21
Is provided with a file access unit 22 for accessing various files 20 in the storage device 8, a determination unit 23, and a list creation unit 24.

Upon receiving the file transfer request, the determination unit 23 causes the file access unit 22 to read the file based on the path name included in the request, and sends the read file as a reply file. If there is no request file, the actual file list created by the list creating unit 24 is sent out as a reply file.

When the list creation unit 24 receives a notification from the determination unit 23 that there is no requested file, the list creation unit 24 determines which stage of the path name in the file transfer request is an actual part by the file access unit 22. Investigate while accessing files through. Then, when it is determined from the path name which part is the illegal part, a list list of file names or directory names actually existing in the corresponding part of the illegal part is created and passed to the judging unit as the actual file list list. It should be noted that the directory referred to in this specification includes everything that functions as a catalog function for a file regardless of its name, and includes, for example, a folder.

Next, each component of the terminal computer 4 will be described. First, in the terminal computer 4, the file determination unit 16 checks a reply file from the remote server computer 6 in response to its own file request, and determines the necessity of re-input. If the content of the reply file is a request file, the content is displayed on the display device 12,
It is also recorded in a storage device (not shown). On the other hand, when the content of the reply file is a real file list, the list is delivered to the pickup unit 17.

The pickup section 17 picks up an existing file name or directory name similar to an incorrect file name or directory name from the existing file list, and transfers it to the selectable input display section 18.

The selectable input display section 18 displays the picked-up file name and the like in a format that can be selected and input from the input device 11, and re-displays the file name (path name) corresponding to the selection input from the input device 11. Is transferred to the file request sending unit 14 as the file request.

Next, the operation of the computer system having the path name re-entry assisting function according to the embodiment configured as described above will be described. First, a designated path for a request file managed by the remote server computer 6 is input from the input device 11 of the terminal computer 4 by the operator. Here, the specification format of the specification path of the file name required for the remote server computer 6 is “machine name / directory name /.. ./Directory name / file name”.

The machine name of the remote server computer is "rm
machine ”, and the requested file name (path name) to be read is“ / rmmroot / dir1 / dir2 / readfile ”. Therefore, the exact file name (specified path) specified from the input device 11 is“ rmmachine ”. / rmmroot / dir1 / dir2 / re
adfile ”.

First, a case will be described in which the path name is correctly input by the operator without erroneous input.
The input designated path is included in the file request from the file request sending unit 14, and the file request is sent to the local server computer 3 on the network A.

This file request is processed by the transfer daemon 19 of the local server computer 3 so that the network B
Is transferred to the remote server computer 6 and received by the file access daemon 21 of the computer 6.

The file access daemon 21 fetches the specified path of the file request, and the file corresponding to the specified path is fetched by the file access unit 22. In this case, since the designated path is formal, the request file is delivered to the determination unit 23 without any particular problem.

This request file is transferred from the file access daemon 21 to the local server computer 3 of the network A as a reply file to the request, and is returned to the terminal computer 4 by the transfer daemon 19.

This reply file is confirmed to be a request file by the file determination unit 16 of the terminal computer 4, and then displayed on the display device 12 or stored, for example. If the reply file is the one requested, the operator is notified that the reading of the file was successful.

Next, a case where the path name becomes incorrect due to an erroneous input by the operator will be described. The operations from the input of the file name by the operator to the point where the file request is delivered to the file access daemon 21 of the remote server computer 6 are the same as those in the above case.

However, in this case, the specified path is incorrect, and the formal specified path “rmmachine / rmmroot / dir1 / dir2 / r
eadfile "instead of the incorrect path" rmmachine / rmm
Root / dir1 / dir2 / redfile ”is included in the file request.

In this case, the judgment unit 23 sets "rmmachine / rmmr
oot / dir1 / dir2 / redfile "to the file access unit 22, the file access unit 22 cannot find the file and returns an access error to the determination unit 23. Since the section is found to be illegal, the determination section 23 sends the list creation section 2
4 is notified to that effect, and the creation of the existing file list is started by the list creation unit 24.

The actual file list is created while the contents of the file 20 are confirmed via the file access unit 22. First, it is determined which part of the designated path is correct.

In this case, "rmmachine / rmmroot / dir1 / dir
It can be confirmed that the file exists up to 2 /, and it is also found that there is no file called redfile. Therefore, the list creation unit 24 uses “rmmachine / rmmroot / dir1 / dir”.
A list of existing files under 2 / "is created.

For example, assuming that the files abc, readfile, readme, and rrr exist in the directory dir2 of the file 20, all the file names become an existing file list. If, for example, a directory is further under the directory dir2, an existing file list including directory names is created.

The actual file list created in this way is passed from the list creating unit 24 to the determining unit 23.
The determination unit 23 returns a reply file. The reply file is the transfer daemon 1 of the local server computer 3.
9 to the terminal computer 4 of the network A,
The file is transferred to the file determination unit 16 via the communication processing unit 15 of the terminal computer 4.

The content of the reply file is determined by the file determination unit 16.
To check that the content is not the requested file originally requested by the terminal computer. As a result, the file determination unit 16 detects that the designated path attached to the file request is invalid, and picks up the actual file list, which is the content of the reply file, from the pickup unit 1.
7 and an error display indicating that the acquisition of the requested file has failed.

From the delivered real file list, an actual file name close to an incorrect file name or directory name is picked up by the processing of the pickup unit 17.

Although various methods of this pickup are conceivable, in the present embodiment, it is realized by the following method. That is, a real file name whose first n characters of the incorrect file name match is picked up. However, if there is no match with the first n characters, an existing file name with the first mn characters matches is picked up. Here, n is a value appropriately set. Also, m is set to an initial value of 1, and when there is no matching file name, the number is increased to 2, 3,..., And when n = m (nm = 0), the existing file list is set. All file names in the list are to be picked up.

When 0 is specified for n,
All file names in the real file name list are targeted. In the case of the present embodiment, for example, if n = 2, “readfile” and “readme” are picked up from the existing file list for an incorrect file name “redfile”. The picked-up real file name is transferred to the selectable input display section 18.

The delivered real file name is displayed on the display device 12 in a state where it can be selected and input. The operator who sees this display knows that he or she mistyped "readfile" as "redfile". So, “readfile”
And "readme", "readfile" is selected, but this time input is not a spelling input with a keyboard but a mere selection, so that no erroneous input occurs.

The result of the selection input is notified to the selectable input display section 18, and the selectable input display section 18 requests the fill request sending section 14 to perform another file transfer request. As the designated path at this time, the exact file name from the existing file list is attached.

Thereafter, a file request is executed again. This time, since the file name is an official file name, the requested file is transferred to the terminal computer 4. As described above, the computer system with a path name re-entry assisting function according to the embodiment of the present invention provides the file access daemon 21 with the list creating unit, and when there is a part where the designated path of the file request is wrong, the part Since a list of the file names and the like corresponding to the specified portions is created and returned, the file requesting side can obtain information on what is wrong in the specified path and accurate file name candidates.

Thus, even if the input path name is incorrect or an ambiguous path name is input, the path name can be re-input properly and easily. That is, it is possible to provide a mechanism that can flexibly respond to an erroneous input or an ambiguous input of the path name of the remote server computer.

Further, in the computer system with the function for assisting in re-entering the path name according to the present embodiment, the terminal computer 4 is provided with the pickup section 17 and the selectable input display section 18, and when the real file list list is received, erroneous input is performed. An actual file name that is closer to the file name is picked up, and the list is displayed so that it can be selected and input. You can help them re-enter their names.

As a result, an error such as “the designated file does not exist” is not simply caused by an erroneous input or the like, and an auxiliary function for the operator to input a correct path name is provided. This is particularly effective for reading a file from a remote machine, and the file can be read easily.

The path name re-entry assist function of the remote machine is effective, for example, when a URL is first entered in the WWW (World Wide Web). It is possible to obtain a real directory name or file name that is close to the specified one, or that is close to the wrong directory name or file name.

The system of the present embodiment is also useful, for example, when acquiring a home page from a web server. (Second Embodiment of the Invention) In the first embodiment, the case of obtaining a file from a remote machine has been described. However, the present invention is effective even in the case of obtaining a file within a local network. . In the present embodiment, a local server computer 3 is connected from a computer terminal 4 in the network A of FIG.
The case where a file request is made to the server will be described.
