Execute function as soon as input is provided in menu drive shell script

Hi All,

I have a menu driven scripts. As you know while running the script we have to input the option such as 1,2, and 3 to execute function accordingly. but after selecting the input we have to press Enter.

My requirement is to execute function as soon as we press the option.

Is there any way to do this? Please suggest.

Display Menu:

Code:
Code:
-------------------------------------
            Main Menu
-------------------------------------
[1] Option 1
[2] Option 2
[3] Option 3
[4] Option 4
[5] Exit
=====================================
Enter your menu choice [1-5] [Default :1]:


Current Shell Script Code:


Code:


Code:
#!/usr/bin/bash

# Menu Item

main_menu()
{

while :
do
	clear
	echo " "
	echo "-------------------------------------"
	echo "            Main Menu "
	echo "-------------------------------------"
	echo "[1] Option 1"
	echo "[2] Option 2"
	echo "[3] Option 3"
	echo "[4] Option 4"
	echo "[5] Exit"
	echo "====================================="
	echo "Enter your menu choice [1-5] [Default : 1]: \c "
	read m_menu
	
	case "$m_menu" in

		1) option_1;;
		2) option_2;;
		3) option_3;;
		4) option_4;;
		5) exit 0;;
                "") option_1;;
		*) echo "\nOpps!!! Please Select Correct Choice";
		   echo "Press ENTER To Continue..." ; read ;;
	esac
done
}

option_1()
{
  echo "option 1"
  echo "\nPress ENTER To Continue..."
    read
	return
}

option_2()
{
	echo "option 2"
	echo "\nPress ENTER To Continue..."
    read
	return
}

option_3()
{
	echo "option 3"
	echo "\nPress ENTER To Continue..."
    read
	return
}

option_4()
{
	echo "option 4"
	echo "\nPress ENTER To Continue..."
    read
	return
}

main_menu

echo(1B)					     SunOS/BSD Compatibility Package Commands						  echo(1B)

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES

The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
