Abstract

PROBLEM TO BE SOLVED: To enable efficient command input by unnecessitating the double input of command by storing the inputted command regardless of the inputted process and performing batch managing of the history of input commands corresponding to all the processes. SOLUTION: First of all, an operator inputs the command from an input/ output device while using a command input part 100. The commands inputted corresponding to the respective processes are batch stored in a command history storage part 1000 of a common area by command input parts 100 (110, 120 and 130) provided for the respective processes. In this case, the commands individually inputted corresponding to the respective processes are stored in the order of input. A computer reads the contents of the command history storage part 1000 prepared in advance through a history display part 200, transfers these contents to an input/output device 10 and displays them for the operator. Thus, the double input of the same command by the user is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a computer equipped with an operating system that operates according to a command input by an operator.
In particular, the present invention relates to a command history management device of an information processing device that manages a history of input commands on a computer when executing an application program.

[0002]

2. Description of the Related Art Conventionally, in an environment of a computer system in which a plurality of processes capable of inputting commands simultaneously exist, such as a multi-window system, a command history is individually managed for each process.

For example, in a csh command of an operating system called UNIX, when a system program called a c shell that accepts a csh command is operated for each of a plurality of windows, a history (data stored in the order of the type and content of the input command) is stored. ) Management,
In the past, the execution of commands was possible only in the closed area of each window.

[0004]

For this reason, in the conventional command history management, a command input to a specific process is recorded in a history file for each process.
For this reason, since the command is not reflected in the command history of another process, there is a problem that even if the user inputs the same command, if the process is different, it is necessary to input again.

The present invention has been made in view of the above conventional example, and stores input commands independently of the input process, and collectively manages the history of input commands for all processes. Therefore, it is an object of the present invention to provide a command history management device of an information processing apparatus which eliminates the need for redundant command input and therefore enables efficient command input.

[0006]

In order to achieve the above object, a first aspect of the present invention provides a command input unit for inputting a command for information processing, and a command input unit for executing the input command. A command history storage unit (1000) for storing the input command regardless of the process and a command execution unit (300) for executing the input command are provided.

According to a second aspect of the present invention, in the command history management device for the information processing apparatus according to the first aspect, a display unit (history display unit 200, input / output device) for displaying a command stored in the command history storage unit. 10) is further provided.

According to a third aspect of the present invention, in the command history management device for an information processing apparatus according to the second aspect, an instruction unit (input / output device 1) for instructing display of a command by the display unit
0) is further provided.

According to a fourth aspect of the present invention, in the command history management device for an information processing apparatus according to the second aspect, a selection unit (input / output device 10) for selecting a command displayed on the display unit is further provided. The same command as the selected command is read out from the command history storage unit by the command execution unit and can be executed.

[0010]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying screens.

FIG. 1 is an overall configuration diagram showing an embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes an input / output device or a terminal device provided with a data input unit composed of a keyboard, a mouse and the like and a data output unit composed of a CRT and the like. Is available. Reference numeral 20 denotes a general-purpose computer equipped with an operation system. As the general-purpose computer, a known computer that can execute a plurality of processes (tasks) in parallel can be used. Since the operating system and the application programs are one means for operating the computer, in the present embodiment, these programs will be described as hardware.

Reference numerals 100 (110, 120, 130,...) Denote command input units provided for each process in the operation system, and deliver commands input from the input device 10 to the respective processes. Usually the operator
By using a device such as a mouse and specifying a window (screen) corresponding to each process, a command is input to a predetermined process.

Commands input to each process are collectively stored in the command history storage unit 1000. The command history storage unit 1000 can use a storage device such as a hard disk storage device.

Reference numeral 200 denotes a history display unit for displaying the contents of the command history storage unit 1000 to the operator via the input / output device 10.

The operator selects a predetermined command from the displayed command history and inputs the command through the input / output device 10. 300 (310, 320, 33
0,...) Are command execution units provided for each process, and execute commands in the command history selected by the operator based on the contents of the command history storage unit 1000. At this time, similarly to the command input units (110 to 130), the operator can specify a process to input a command using a device such as a mouse.

Note that 100 to 30 in the computer 20
The functions of the units 0 and 1000 are, of course, the arithmetic processing unit (CPU) in the computer and the processing memory (RA).
M), a control memory (ROM) that stores a processing procedure represented by a flowchart described later, an interface that exchanges information, and the like.

[Explanation of Specific Example] FIG. 2 shows an example of command input. (A), (b) and (c) of FIG.
It shows a sequence of commands input to three different processes, Process 1, Process 2, and Process 3. The numbers 1001 to 1010 added to the commands are shown in the order of input of the commands. In this example, the numbers are input in the order of [command A], [command α], [command B], [command X]. Shall be. In this example, a command without options or arguments is used as an example for simplicity, but it is obvious that these can be added.
In addition, the present device can be similarly applied to a command input using a mouse, a touch panel, a voice, and the like, in addition to a command input by text from a keyboard. Further, the number of processes for receiving a command input may be any number. In this example, three processes are used for convenience of explanation.

The operation procedure of this embodiment will be described with reference to the flowchart of FIG. FIG. 3 functionally expresses a processing procedure executed by the arithmetic processing unit in the computer 20 for explanation.

First, in step S1, an operator inputs a command shown in FIG. Commands (FIGS. 2A, 2B, and 2C) input to each process are stored in a command input unit 100 (110, 120,
130), they are collectively stored in the command history storage unit 1000 which is a common area. FIG. 4 shows the contents of the command history storage unit 1000 when the input shown in FIG. 2 is performed. Commands input individually for each process are stored in the input order (1001 to 1010).

In step S2, the computer 20 executes S1
The contents of the command history storage unit 1000 created in step (1) are read by the history display unit 200, transferred to the input / output device 10, and displayed to the operator.

In this example, the process of S2 is performed every time immediately after the process of S1, but it is naturally possible to display this only when an instruction is given from the operator via the input / output device 10. .

FIG. 5 shows an example of a history display instruction and a display method.

The operator inputs the [history display] command 3A to the process 3, and instructs the history display unit 200 to display the command history stored in the command history storage unit 1000 at that time.

The command input unit 100 that has detected the input of the [history display] command by command identification attaches a history number (numerals 1001 to 1010) to the history display unit 200 and sends the contents of the command history storage unit 1000 to the operator. To be displayed.

At this time, in this example, the command history is displayed as text on the same window as the command input, but a new window can be created and displayed separately.

In step S3, the command selected by the operator from the command history displayed in S2 is executed by the command execution unit 300 (310, 320, 330).

The command execution unit 300 reads out and executes the same command as the command input by the operator from the command history storage unit 1000.

FIG. 6 shows an example of command execution.

In FIG. 6, the operator sends a command to the command execution unit 3 (circuit code 330) provided on the process 3.
[History 1006] A command has been entered. As a result, the [command Y] command executed in the past for process 1, which is another process, is selected and executed. At this time, the command history 1000 is referred to for checking the command to be actually executed from the command history number (1006 in this case) input by the operator.

In this example, the command in the history storage unit is selected based on the history number. However, the command history display in step S2 is expanded to a button or the like which allows a mouse to be selected, and the operator instructs with the mouse. A simple system is also possible.

[0032]

As described above, according to the first to fourth aspects of the present invention, commands are collectively stored in the order of input irrespective of the process, so that the same commands as in the prior art are duplicated. User input can be avoided.

According to the third aspect of the present invention, since the history of the command can be displayed as required, the display can be used not only for re-inputting the command but also for detecting an erroneous input.
