FTP zero size file
Hi AM using unix Aix Ksh
I need to clarify regarding sending the zero size file to another server.

Code:
VAL=ftp.sh -c put souce_file Dest_file $1 $2 $3 $4 $5
 
$VAL 2 > $ERR

When am Sending the Zero Size File getting alerts netout write returned Zero.
But i would like to know $VAL variable what error code or what value is present in $VAL variable when Sending the Zero Size File ?

If any one knows tell me tanks in advance...

Its a warning message you receive when you transfer the 0 byte file via ftp.
If you want to redirect it use 2> /dev/null in your ftp.sh script

If i am not wrong it will return status code as 0 as its just a warning message. For more information you have to read through write system call and see how fd behaves Smilie

Thanks Vidyadhar ..

The status code is not 0 , its return some other value .
Code:
$VAL 2 > $ERR
if [ $VAL -ne 0 ]
then
      echo "FTP failure"
else
     echo "FTP SUCCESS'
fi

when i run this am getting FTP Failure. want to know $VAL value ret code ?

I seem to recall a thread about this before...

How is this an error? You're writing a 0-byte file, and it complains that 0 bytes are written... which is exactly what you wanted, so nothing to worry about apparently.

This is not how you check the return code of something, the $? variable holds the return code.
