As I said in my post#2, use of a .netrc file should avoid the need to supply a userid/passwd for the ftp server.

Yes, many times I have built a command file to input to ftp:

Code:
$ ftp 'ftpserver' < 'command file' 1> /dev/null

and it works fine. You have to be careful of how to trap errors though. You also need to ensure that the last line of your command file is 'quit' to ensure control is passed to the next line of your script when ftp operation is done.

When you say that it doesn't work; in what way????? Error message or what? Give us all a clue.

Do you need to use a non-standard ftp port? If not, why try and specify it?
Hi hicksd8,

Thanks much for your response.
The intention was not to bump posts.

I was able to connect to the MVS password less using .netrc and give the command to put files into mvs.

Whereas when i create a file dynamically(because i dont know the number of files I will have at any point which is to be ftp'ed) and use it in Ftp command its not working properly.

Output:
Code:
USER@SERVER:MY_PWD>ftp -siv remote_server.abcd.com 12342 << cat /user_home/ftp.batch.file
>

type binary
passive
$(cat $TMP_BATCH_FILE)
bye
EOF
}

But, the AIX ftp man page that I have access to doesn't include a -s option. And, if you're trying to use ftp to copy the content of the file named by the expansion of $TMP_BATCH_FILE from AIX to MVS, the correct way to do that would be something like:
put $TMP_BATCH_FILE
not catting a binary file into a here document.

Alternatively, you could use simple redirection instead of a here-document:
Code:
f_FTP_MVS()
{
	echo "user $REMOTE_USER $REMOTE_USER_PASS" > "$TMP_BATCH_FTP"
	echo 'type binary' >> "$TMP_BATCH_FTP"
	echo 'passive' >> "$TMP_BATCH_FTP"
	echo "put '$TMP_BATCH_FILE'" >> "$TMP_BATCH_FTP"
	echo 'bye' >> "$TMP_BATCH_FTP"
	ftp -sinv "$REMOTE_SERVER" "$REMOTE_PORT" < "$TMP_BATCH_FTP"
}

And, of course, unless the FTP protocol includes character set translations when moving from AIX to MVS... since AIX works in ASCII/ISO 8859-1/UTF-8 and MVS works in EBCDIC, you may also need a step somewhere to convert your ASCII requests and file contents into EBCDIC. One possible way to do that if you need to is with dd conv=EBCDIC or dd conv=IBM depending on which variant of EBCDIC is used on your target MVS system.
Thanks Don.

Since I am polling a directory and don't have any idea of how may files will be there at any given moment, I will have to go by the approach of creating a dynamic file list and give it as input to the ftp command.


I try with your approach and get back here.

To answer your question., the file is already in EBCDIC format and just needs to be transferred in binary mode.


Thanks a lot for your guidance.
