The nice thing about FTP - and also the problem with FTP - is that it has zero features.
Can you ask FTP if the file uploaded successfully? Nope.
Can you ask FTP for a file checksum or anything like that to verify it? Nope.
Can it tell you the most recent file? Nope.
Can you ask it if a file is there at all? Nope.
Can it tell you anything? Nope. Well, a directory listing. That's it.
So, you can depend on FTP being reliably unhelpful. But there's old-fashioned ways to trick it into doing what you want:
Code:
ftp <<EOF
cd /remote/incomplete
put localfilename
rename /remote/incomplete/uploadedfile /remote/complete/uploadedfile
This prevents partial uploads from appearing in /remote/complete. If the connection is broken early, the file will never get renamed.
Then you can get the directory listing from /remote/complete to see if the file you wanted is in it.

A. Using FTP method :- Will it not be possible to verify the file transferred and can the restart ability of the script be not achievable?
It will require brute force.
Connect with FTP, saving all output to a file.
Get directory listing.
Quit.
Process directory listing in script to remove all lines except the directory listing.
Check if the directory listing contains the file you uploaded.
That sort of thing.

B. Is using SFTP less secure when compared to FTP -s to transfer files from AIX to Mainframe.?
Do you even have ftp -s? That's a very rare feature.
Quote:
Will there be any loss in data .i.e., will the data get corrupted?
sftp is less likely to corrupt your data than FTP.
FTP's "binary" feature is only there because, in the beginning, ftp was expected to translate text files automatically (i.e. EBCDIC to ASCII) so the recipient could read them. FTP mangles files because it's trying to process all downloads as text! And it always does that unless you force it not to with binary! sftp just doesn't do that, at all, period. It transfers the file as-is, always.
