Abstract

PURPOSE:To easily input a command by storing a command and a desired command alias indicating the command, and interpreting and executing the command corresponding to the inputted command alias when this command alias is inputted. CONSTITUTION:A UNIX command 310 to be used and a command alias 320 indicating the name of the command, are preliminarily registered in a command table 3 which executes the function of a storage means. A user interface 1 compares an inputted command name 2(including the command alias and the command alias in an abbreviated form) with the command name registered in the command table 3, and activates the pertinent command when they are coincident, and operates a processing corresponding to the key operation(command input) of a user after that when they disagree. Thus, the user can input the command by a comprehensible command name.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a user interface system that interprets and executes input commands.

[Conventional technology]

Traditionally, conversational operating systems (hereinafter referred to as O8)
) is UNIX.

As is well known, in the UNIX hierarchical model, a virtual machine (a collection of software resources) is the point of contact with the user.
The user interface layer is located at the top, and all messages from the user to the system go through that user interface layer.

When a user sends commands to the system, i.e. UNIX
When specifying (requesting) various services provided by the system in the single-layer model (service model) of , you can do so by inputting UNIX commands as an interface language.These input UNIX commands are then sent to the shell (as a command interpreter). 5hell) can obtain the result for the requested service by interpreting and executing it.

Therefore, the conventional UNIX user interface was changed from "Kyoritsu Shuppan Co., Ltd. (publishing company name)" to "Showa 6
“(bi
The one described on pages 124 to 129 of the special edition "Latest UNIXJ (Book Title)" (hereinafter referred to as literature) is known.

[Problem to be solved by the invention]

However, in the user interface described in the above-mentioned literature, it is not possible to perform an ambiguous search for a command name, or even if an ambiguous search is possible, command name candidates are always displayed, and it is difficult to select a command from among multiple candidates. To make a selection, the user must enter the command name himself.

Also, although it is possible to give a command a different name, the name of the command cannot include a space character, which makes it difficult to intuitively understand the operation of the command from the command name.

This invention was made in view of the above circumstances, and an object of the present invention is to provide a user interface system that allows even users who are unfamiliar with the command system of a certain operating system to easily input commands. .

[Means to solve the problem]

In order to achieve the above object, the knee sign tough ace system according to the first invention includes a storage means for storing in advance a predetermined command and a command alias indicating a name different from the name of the command, in association with each other; an input means for inputting a command alias registered in this storage means; and a user interface means for interpreting and executing a corresponding command if the command alias input by this input means is stored in the storage means; It is equipped with

Further, the user interface system according to the second invention includes a storage means for storing in advance a predetermined command and a command alias indicating a name different from the name of the command; An input means for inputting an abbreviated command alias corresponding to the command alias, and based on the abbreviated command alias input by this input means, a corresponding official command alias is searched from the storage means and the corresponding command is executed. and a user interface means for interpretation and execution.

[Effect]

According to the first invention, a command and a desired command alias indicating the command are stored in the storage means, and when the command alias stored in the storage means is input by the input means, the user interface Since the means interprets and executes the command corresponding to the input command alias, the user can input a command using a desired command alias that is easy to understand.

Further, according to the second invention, a command and a desired command alias indicating the command are stored in the storage means,
When an abbreviated command alias corresponding to a command alias stored in the storage means is input by the input means, the user interface means recognizes a formal command alias from the input abbreviated command alias and selects the corresponding command alias. Since the command corresponding to the recognized command alias is interpreted and executed, the user can enter a command using the abbreviated form of the command alias, even if the user does not know the exact command alias. .

〔Example〕 Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a diagram for explaining an overview of a user interface system according to the present invention.

In the figure, a user interface 1 corresponds to the user interface layer located at the highest level in the hierarchical model of the operating system (hereinafter referred to as O5), and serves as an interface between the user and the system. Further, the user interface 1 fulfills the function of the above-mentioned user interface means,
The input command name 2 (including command aliases and abbreviated command aliases) is compared with the command name registered in command table 3 (details will be described later), and if they match, the corresponding command is If there is no match, processing is performed according to the user's subsequent key operations (command input).

In this embodiment, since UNIX is used as the O8, the user interface l is configured on a shell (5hel l ) which is a command interpreter. Furthermore, since the UNIX hierarchical model (configuration of O8) is well known, its explanation will be omitted in this embodiment.

A UNIX command 310 to be used and a command alias 320 indicating the name of the command are registered in advance in the command table 3 which functions as the storage means described above.

The command alias 310 written in the command table 3 may include any characters as long as they can be input from an input means such as a keyboard. However, UNIX that is started
The characters used to separate the command name from the command field cannot be used. In addition, it is possible to write a command alias that is similar to the English notation, and by specifying (inputting) the command alias when inputting a command, it becomes easier to intuitively understand the operation of the command from the command name.

Furthermore, if the command alias in the command table 3 has a sufficient number of characters to be uniquely recognized, the command input from the user can be shortened (abbreviated).

Here, the user selects the UNI
Corresponding to "IIs" as the X command 310-n,
“Li5t Direct as command alias 320
If the user has registered "Li5t Directory" in the command table 3, the user can input the command name corresponding to "ls" in an alias format as "Li5t Directory", and can also enter "Li5t" or 'Ll'. Like “Li5
It is also possible to input an abbreviated command alias that omits the command alias “tDirectory”.

Incidentally, the UNIX command "is" is a command for displaying a list of files.

FIG. 2 is a block diagram showing an embodiment of a computer system to which the user interface system according to the present invention is applied.

In the figure, the computer system includes an input device 10 for inputting commands, a display device 2 for displaying output information such as the input commands, and 08 (UNIX).
, a disk 30 that stores various programs, a command table 3, and various data, a main memory 40 that stores O81 programs and various data loaded from the disk 30, input commands and various data, and programs including O8. A central processing unit (hereinafter referred to as CPU) 50 executes the following.

Note that each of the above parts is connected to a bus 60,
The CPU 50 is set to control each unit connected to it via a bus 60.

The input device 10, which functions as the input means described above, is equipped with a keyboard provided with a back key, an N key, a P key, a control key, a return/line feed key, an end key, various character keys, and the like. You can enter a command name by pressing the various character keys, delete the already input character string by pressing the back key, and press the control key and N key at the same time (at this time, Acts as the next candidate key.) By doing so,
You can display the next candidate of the currently displayed candidate, and by pressing the control key and P key at the same time (at this time, it functions as the previous candidate key), you can display the next candidate of the currently displayed candidate. Candidates can be displayed.

Next, in the above-described configuration, a computer system.

The command input processing operation will be explained with reference to FIG.

First, when the login procedure is completed, the knee interface 1 loads the control 3 from the disk 3o into the main memory 4o, reads the contents of the command table 3 (step 01), and then displays the screen of the display device 20. Display the prompt (two-prompt symbol) above Step 10
2) Wait for input from the user.

When the code corresponding to the key operation from the user is entered (
Step 10B), the user interface 1 determines the type of input character (code).Step 1
04), perform processing based on this judgment result.

In the case of a line break, search in command table 3 for the name that is missing from the character string input so far in step 10.
5) It is determined whether the input character string matches the command alias registered in the command table 3 (step 106).

- Mulberry entered as an abbreviated command alias in Uni
If a character string or a character string entered as a formal command alias matches a single name, f performs processing according to the input format of the command name (step 10).
7).

In other words, ■: In the case of an abbreviated command alias For example, if the character string “Li5t” is entered in the abbreviated form, the name indicated by the input character string is spelled out in full (in this example, “Li5t Dlreeto
After executing the command corresponding to that name (in this example, "gs") (step 109), the process returns to step 102 and executes the steps from this step onwards. That is, An ambiguous search is performed using the abbreviated command alias, and the corresponding command is executed.

■: For official command alias For example, if the character string "Li5t old rector'J" is input, it will be displayed in full spelling on the display screen of the display device 20, so the above step Proceed to 109.

On the other hand, in step 106, if the input character string matches multiple command aliases or does not match any command alias, r' is displayed on the display screen of the display device 20.
? 'J mark is displayed (step 110), and the process returns to step 10B to execute this step and subsequent steps.

Next, the displayed r'? 'Perform processing according to the content of the key operation by the user who referred to the J mark.

I: If the back key is pressed, delete the character string that has already been input (step 111) and then proceed to step 1 above.
Return to step 03 and execute the steps after this step.

In this case, the user will have to enter the command alias again.

■When the secondary candidate key is pressed (when the control key and N key are pressed at the same time), the next candidate character string for the input character string is displayed with reference to command table 3, and then ( Step 112), the process returns to step 103 and executes this step and subsequent steps.

■: When the previous candidate key is pressed (when the control key and P key are pressed at the same time), refer to command table 3, display the previous candidate character string for the input character string, and then ( Step 113), the process returns to step 103 and executes this step and subsequent steps.

Note that steps 112 and 113 are repeated until the line feed key is pressed.

Finally, if the end key is pressed, the user interface ends the process.

As described above, according to this embodiment, it is possible for the user to input a command using a command alias that is easy to understand. Furthermore, if you do not know exactly the registered command alias, you can perform an ambiguous search by inputting the first few characters of the command alias. When performing an ambiguous search, a plurality of candidates can be selected using the next candidate key or the previous candidate key, which reduces the effort required to input commands. Furthermore, since the command name can include a space character, it becomes easier to intuitively understand the operation of the command based on the name.

Therefore, even a user who is unfamiliar with the UNIX command system can easily input commands.

〔Effect of the invention〕

As explained above, according to the user interface system according to the first invention, when a command alias registered in the storage means is input, the corresponding command is interpreted and executed. This means that commands can be input with easy-to-understand command names, and services can be easily and quickly requested from the system.

Further, according to the user interface system according to the second invention, when an abbreviated command alias corresponding to a command alias stored in the storage means is input, a formal command alias corresponding to the input abbreviated command alias is input. The system interprets and executes the command corresponding to the command alias, so even if the user does not know the exact command name, the user can enter the command using the abbreviated command alias, and the system You can request services easily and quickly.
