fgrep fails...!?

Hi all,

I need to transport a number of files from one server to other. I like to ensure the integrity using file checksum values.
The action plan is,
1. create the list of checksum values for all the files using cksum command in source server.
2. Transfer all the files including the file genered in step 1 to destination server.
3. Take the checksum of each file and compared with the file generated in step 1 using fgrep command.

I have a bash shell script to verify this.
The issue for me, in step 3 when i compared, the fgrep didn't find out even the checksum values changes.
My script is as below:

clear
cksum *.* > tmp.txt
while read N
do
fgrep -c $'(echo $N)' tmp.txt
done<x.txt

Remarks: tmp.txt - the file which generated in the destination server after copied. x.txt - the file which generated in source server (step 1) and transfered along with the files.

Please help me in this regard. Also let me know, any other ideas.

regards,
Sethu.

shishi_authenticator_set_cksum(3)				      shishi					 shishi_authenticator_set_cksum(3)

NAME

       shishi_authenticator_set_cksum - API function

SYNOPSIS

       #include <shishi.h>

       int shishi_authenticator_set_cksum(Shishi * handle, Shishi_asn1 authenticator, int32_t cksumtype, char * cksum, size_t cksumlen);

ARGUMENTS

       Shishi * handle
		   shishi handle as allocated by shishi_init().

       Shishi_asn1 authenticator
		   authenticator as allocated by shishi_authenticator().

       int32_t cksumtype
		   input checksum type to store in authenticator.

       char * cksum
		   input checksum data to store in authenticator.

       size_t cksumlen
		   size of input checksum data to store in authenticator.

DESCRIPTION

       Store  checksum value in authenticator.	A checksum is usually created by calling shishi_checksum() on some application specific data using
       the key from the ticket that is being used.  To save time, you may want to use shishi_authenticator_add_cksum() instead,  which	calculates
       the checksum and calls this function in one step.

RETURN VALUE

       Returns SHISHI_OK iff successful.
