Check file size before and after scp

Dears does anybody know how to check the file size on server A and server B before and after scp using KSH. Script should be on server A.

I will be using it for the below mentioned scenario:

I have written a code to fetch files from server A, move it onto server B compress it and save it on server C and delete the files from server A and B.

But now my concern is to check the size and filename before deleting from server A and B.. the checks are required between server A and server B before deleting from server A & between server B and server C before deleting from server B. The code is running on server B......

Code:

#########

FILELIST=`ssh root@ServerA 'find /dir1/dir2 -type f -print -mtime +12'`
for f in $FILELIST

do
dirname=`basename $f`
mkdir -p /CGW_Backup/egcdr/`echo ${dirname:0:6}`
scp -r usn@serverA:$f ServerB`echo ${dirname:0:6}`
done


#checking file name and sizes betwen server A and B




LOCAL_FILELIST=`find ServerB`
for f in $LOCAL_FILELIST
do
bzip2 -9 $f
done



scp -r ServerB/* usn@ServerC:/mnt/pools/A/A0/Backups/


#checking the file name and sizes for between server B and server C


for f in $FILELIST
do
removing the files from CG and Hstore
`ssh usn@serverA 'rm $f'`
done

rm -r /serverB/*

LEARN ABOUT FREEBSD

sigreturn

SIGRETURN(2)						      BSD System Calls Manual						      SIGRETURN(2)

NAME

     sigreturn -- return from signal

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <signal.h>

     int
     sigreturn(const ucontext_t *scp);

DESCRIPTION

     The sigreturn() system call allows users to atomically unmask, switch stacks, and return from a signal context.  The thread's signal mask and
     stack status are restored from the context structure pointed to by scp.  The system call does not return; the users stack pointer, frame
     pointer, argument pointer, and processor status longword are restored from the context.  Execution resumes at the specified pc.  This system
     call is used by the trampoline code and longjmp(3) when returning from a signal to the previously executing program.

RETURN VALUES

     If successful, the system call does not return.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

     The sigreturn() system call will fail and the thread context will remain unchanged if one of the following occurs.

     [EFAULT]		The scp argument points to memory that is not a valid part of the process address space.

     [EINVAL]		The process status longword is invalid or would improperly raise the privilege level of the process.

SEE ALSO

     sigaction(2), setjmp(3), ucontext(3)

HISTORY

     The sigreturn() system call appeared in 4.3BSD.
