HI.. Check the below code for compare two files.

rm -f c.txt
t=`sdiff a.txt b.txt | grep "|" | wc -l`
if [ $t -eq 0 ]
then
echo "File are same"
else
echo "Hi"
sdiff a.txt b.txt | grep "|" | nawk '{
s = sprintf("%s/%s/g",$1,$3);
print s;
}' >> c.txt

cnt=1
str=" "
for i in `cat c.txt`
do
if [ "$cnt" -eq "1" ]
then
cnt=`expr $cnt + 1`
sed 's/'"$i"'' a.txt >> d.txt
else
cnt=`expr $cnt + 1`
sed 's/'"$i"'' d.txt >> d.txt
fi
done

p=`cat a.txt | wc -l | awk '{print $1}'`
echo $p
tail -$p d.txt > c.txt
rm -f d.txt
fi

Note:
Above code works only when both the files are same line.

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.
