thank you
Its really working awesome.But my question is my original file1.txt and file2.txt have records in millions,so does it take huge time or efficient enough.
---------- Post updated at 11:21 PM ---------- Previous update was at 11:12 PM ----------
i need to compare the same for filed3 also.Iam java developer so no idea about shell script please help me regarding this also.I mean to say if filed3 filed2 changes i need to show both changes.
File1.txt
'393200103088';'TIM';'20060207'
File2.txt
'393200103088';'TIM';'20060208'
common.txt(Filed3 has changed for filed1)
'393200103088' '20060201' '2006208'
---------- Post updated at 11:39 PM ---------- Previous update was at 11:21 PM ----------
I had generated file3.txt by the following command.
diff file1.txt file2.txt > file3.txt
If you look into file3.txt
The records missing from file2 started with < symbol.
And the records missing from file1 started with > symbol.
And it also has coommon records(coomon first field)using this i have to generate same three files as i have mentioned in previous thread.
1.misssed_file1.txt
2.missed_file2.txt
3.common.txt
< '393200103052';'H3G';'20081204'
< '393200103059';'TIM';'20110111'
< '393200103061';'TIM';'20060206'
< '393200103064';'OPI';'20110623'
> '393200103052';'HKG';'20081204'
> '393200103056';'TIM';'20110111'
> '393200103088';'TIM';'20060206'
I think here > and < symobls are helpful to generate required files.
please help me regarding this.

LEARN ABOUT PHP
phar.interceptfilefuncs
PHAR.INTERCEPTFILEFUNCS(3) 1 PHAR.INTERCEPTFILEFUNCS(3)
Phar::interceptFileFuncs - instructs phar to intercept fopen, file_get_contents, opendir, and all of the stat-related functions
SYNOPSIS
finalpublicstatic void Phar::interceptFileFuncs (void )
DESCRIPTION
instructs phar to intercept fopen(3), readfile(3), file_get_contents(3), opendir(3), and all of the stat-related functions. If any of
these functions is called from within a phar archive with a relative path, the call is modified to access a file within the phar archive.
Absolute paths are assumed to be attempts to load external files from the filesystem.
This function makes it possible to run PHP applications designed to run off of a hard disk as a phar application.
PARAMETERS
No parameters.
RETURN VALUES
EXAMPLES
Example #1
A Phar.interceptFileFuncs(3) example
<?php
Phar::interceptFileFuncs();
include 'phar://' . __FILE__ . '/file.php';
?>
Assuming that this phar is at /path/to/myphar.phar and it contains file.php and file2.txt, if file.php contains this code:
Example #2
A Phar.interceptFileFuncs(3) example
<?php
echo file_get_contents('file2.txt');
?>
Normally PHP would search the current directory for file2.txt, which would translate as the directory of file.php, or the current direc-
tory of a command-line user. Phar.interceptFileFuncs(3) instructs PHP to consider the current directory to be phar:///path/to/myphar.phar/
and so opens phar:///path/to/myphar.phar/file2.txt in the above example code.
