How to trap sftp upload sucess or failure in unix ksh?

Trying to upload several files to a sftp site using a shell script (KSH) and wanted to find out if all files uploaded 100% or not. Can anyone tell me how to accomplish this?

Does your sftp program set the exit status in a meaningful way?

Code:

$ false
$ echo $?
1
$ true
$ echo $?
0

Most programs return 0 on success, and a variety of small positive integers representing various kinds of 'problem'.
'grep' for example returns 0 for matching text, 1 for no matches, 2 for missing files.

Yes, it does give return codes.

But how would I know which file succeeded or not?

Do I need to run echo $? inside the sftp session or after it exits out of the sftp session?

Can you please give me a sample script.

You can log process and if any errors occurred parse the log file, For example:

Code:

$ cat test_sftp.sh
#!/bin/ksh
# test_sftp.sh
sftp -b /dev/stdin -o BatchMode=yes -o IdentityFile=/export/home/user/.ssh/id_rsa -o Port=22 user@host 1>sftp.log 2>&1 <<ENDSFTP
put file_does_not_exist_1.txt
quit
ENDSFTP
rc=$?
if [[ $rc != 0 ]]	then
	print "***Error occurred...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
else
 print "***Successful transfer...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
fi


$ test_sftp.sh
***Error occurred...1 2013-01-28-11.28.26


$ cat sftp.log
Connecting to host...
sftp> put file_does_not_exist_1.txt
File "file_does_not_exist_1.txt" not found.
