I have a shell script which delivers the file to the SERVER B using SFTP.
I'm calling this script from java.
Now I need to find the exit status of the sftp, with the help of this I can find whether it was success or unsucess.

I'm using the variable "$?" to get the status and it is always 0 even if it not able to deliver the file.

Can anyone please help me out in this. This is very urgent.

Here is the script:
sftp $1@$2 <<EOC

cd $3

lcd $4

put $5

EOC

if [ $? -ne 0 ]
then
echo "SFTP ERROR" >> FILE
exit 9
fi

echo "SFTP Complete" >> FILE

Here is the java code:

//Execute the shell script which drops the file to destination using SFTP
Process process = runtime.exec("sftpFile.sh" +" " +user+" " + host+" " + targetfile+" " + localDir +" "+fileName,null,dir);

process.waitFor();

Any help is appreciated.

Thanks in Advance

ftp and sftp are supposed to write status codes(ftp) or messages(sftp) to stdout, the $? value of sftp, if it connects okay to a remote host, will be 0. The status of an individual operation is displayed on stdout. "OK" means whatever operation was attempted completed succesfully.

However, the actual text you get back may depend on whose sftp you use. So checking for errors is interesting.
Consider libcurl classes for your java? There are libcurl routines that will perform sftp operations and give you a status back.
