function flow

step 1.) Calling javascript function using button (CLIENT SIDE)

<input class=”button” name=”test” value=”Test” type=”test”>

onclick=ajax_test();>

step 2.) Function definition … Here it calls server function which is named as “loading” … (CLIENT SIDE)

function ajax_test()
{
alert (”sdsdf”)
x_loading(ajax_test_diaplay)
}

Note: Here ajax_test_display is a function which will handle the
returned result

step 3.) PHP Coding .. (SERVER SIDE) (you should include Sajax2.php file)

function loading()
{
return (”balavignesh”);
}
sajax_export(”loading”);

step 4.) Displaying the result (CLIENT SIDE)

function ajax_test_diaplay(ret_value)
{
alert (ret_value)
}

grep command form (syntax)

grep “text string to search” directory-path

Examples

For example search for a string called redeem reward in all text files located in /home/tom/*.txt directory, use
$ grep "redeem reward" /home/tom/*.txt

Task: Search all subdirectories recursively

You can search for a text string all files under each directory, recursively with -roption:
$ grep -r "redeem reward" /home/tom

Task: Only print filenames

By default, grep command prints the matching lines You can pass -H option to print the filename for each match.
$ grep -H -r “redeem reward” /home/tom
Output:

...
filename.txt: redeem reward
...

To just print the filename use cut command as follows:
$ grep -H vivek /etc/* -R | cut -d: -f1
Output:

...<br />filename.txt<br />...
