Not able to capture sftp error in Korn Shell

I am not able to capture error condition in sftp in Korn Shell

sftp  batch@uat >abc 2>&1 << ENDFILE
   cd public
   put /data/WELCOME_55
if [[ $ret_val -eq 0 ]]
   print file "copied successfully"
   print file "NOT copied successfully"
return 0

Now the file /data/WELCOME_55 does not exist. I am seeing the error message in file abc. But ret_val is zero.

Any help?

Thanks - Soham

I couldn't get it to work, either.

Maybe you could check if the file exists after SFTP is done?

if [ -f filename ]; then

Yes that will work if the file does not exist in destination server. If it exists and the sftp has failed, still we will get SUCCESS messaage.

Try running sftp in batch mode...see man pages, should return 1 in this case. Also try running sftp in verbose modes so you see the nature of the failure.

Having read the man page, I'd assume that would work.

Here's what I use!
$ ssh someone@somewhere '[ -f /tmp/temp.txt ] && cat /tmp/temp.txt || exit 1' > temp.txt  
$ echo $?

$ ssh someone@somewhere 'touch /tmp/temp.txt'

$ ssh someone@somewhere '[ -f /tmp/temp.txt ] && cat /tmp/temp.txt || exit 1' > temp.txt  
$ echo $?
