How to list the Hooks and order of execution in current loading page? [duplicate]

I need to know the list of hooks that are called in the current page . How to identify the priority assigned to the action and filters in the action . If i want to remove the default action on word-press . It cause any error ? May i overwrite the default action that to be execute?

add_filter( $tag, $function_to_add, $priority, $accepted_args ); 

in this case i change the priority as 50 . i don’t get any changes compare with 10 or Default. if This Priority value is for order of execution means i need to change the values as bigger or smaller?.

Paste this into your functions.php

//LIST ALL HOOKS

function dump_hook( $tag, $hook ) {
    ksort($hook);

    echo "<pre>>>>>>\t$tag<br>";

    foreach( $hook as $priority => $functions ) {

    echo $priority;

    foreach( $functions as $function )
        if( $function['function'] != 'list_hook_details' ) {

        echo "\t";

        if( is_string( $function['function'] ) )
            echo $function['function'];

        elseif( is_string( $function['function'][0] ) )
             echo $function['function'][0] . ' -> ' . $function['function'][1];

        elseif( is_object( $function['function'][0] ) )
            echo "(object) " . get_class( $function['function'][0] ) . ' -> ' . $function['function'][1];

        else
            print_r($function);

        echo ' (' . $function['accepted_args'] . ') <br>';
        }
    }

    echo '</pre>';
}

function list_hooks( $filter = false ){
    global $wp_filter;

    $hooks = $wp_filter;
    ksort( $hooks );

    foreach( $hooks as $tag => $hook )
        if ( false === $filter || false !== strpos( $tag, $filter ) )
            dump_hook($tag, $hook);
}

Write this on index.php or single.php or any other page to see the filters applied to a particular function along with priority.

<?php  list_hooks(); ?>

This method even show your own create filters.
