How to call a function in Shell..?
#!/bin/bash

Code:
FUN_ECHO(){
echo $1
}

FUN_ECHO "hi how are you ?"

This code will work fine.


BUT is it possible to make the following to work ?
Code:
FUN_ECHO "hi how are you ?" 

FUN_ECHO(){
echo $1
}

I know that the code will be executed line by line. But i have a number of functions.. which may call another function and may return to some other... and so and so...

is there any way to call as in Java...?? [ i mean from anywhere in the same page/script]

NAME

       CPANPLUS::Shell

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
