How to prompt user to define a variable?

Hi everyone,

Is it possible to define blank vaianbles and prompt user to fill them during the script execution?

A very simple example:

Code:
INPUT=
OUTPUT=

cut -f1-4 $INPUT | sed 's/hello/goodbye/g' | sort -uV > $OUTPUT

Thank you in advance!

Best wishes

XHPPrompt(3X)															     XHPPrompt(3X)

NAME
XHPPrompt - Send a prompt to an extended input device. SYNOPSIS
#include <X11/XHPlib.h> int XHPPrompt (display, deviceid, prompt) Display *display; XID deviceid; unsigned int prompt; ARGUMENTS
display Specifies the connection to the X server. deviceid Specifies the ID of the desired device. Prompt Specifies the Prompt to be sent. Valid values are: GENERAL_PROMPT, PROMPT_1, PROMPT_2, PROMPT_3, PROMPT_4, PROMPT_5, PROMPT_6, PROMPT_7. DESCRIPTION
This request is part of an HP-proprietary extension to X. Its functionality has been superseded by the standard X input device extension XChangeFeedbackControl request. You should use XChangeFeedbackControl instead of XHPPrompt if possible. This request sends a prompt to an input device. A prompt is an audio or visual indication that the program controlling the input device is ready for input. The program may indicate that status by turning on a prompt on the appropriate input device. Not all input devices support prompts and acknowledges. Any device that does support a particular prompt will also support the corresponding acknowledge. To determine whether an input device supports a particular prompt and acknowledge, the io_byte field of the XHPDeviceList structure should be examined. The format of this structure is described in the documentation for the XHPListInputDevices request. RETURN VALUE
none DIAGNOSTICS
BadDevice An invalid device ID was specified. BadValue An invalid prompt was specified. FILES
