Thanks for the reply.

I heard from my colleague that, there is some restriction set in sftp server, that's why heredoc is executing only one command. If I put get as a first command in heredoc, I'm able to get file from sftp server. Colleague told me that he faced this problem and resolved this by using batch file.

I'm having doubt that, Is it possible to make such restrictions in server?
Have anyone of you faced these kind of problem before?

If you are able to run the commands explicitly with the same user, there shouldn't be any problem regarding access. [ Though I don't have much idea about that part ]. May be other could help us.

Just for a try, you could try to run those commands on command line (with here doc).
Press "enter" after each line and see what happens.

Code:
$>> sftp user@host <<FTP
lcd /WEBSERVER_LINK/data_logs/
ls -l pub/csidata/GeneralAppFields_8_1_Feed.out
get pub/csidata/GeneralAppFields_8_1_Feed.out
quit
FTP

Thanks anchal.

I tried this heredoc in command line, I'm getting the same result which I'm getting in script.
Code:
bash-3.00$ /export/opt/SCssh/3.7.1_C0/bin/sftp  csi@192.168.1.100 <<FTP
> lcd /WEBSERVER_LINK/data_logs/
> ls -l pub/csidata/GeneralAppFields_8_1_Feed.out
> get pub/csidata/GeneralAppFields_8_1_Feed.out
> quit

...but you're still not using -b -, which I really suggest you do. The noninteractive behavior may be quite different.

scp does a simple file-copy. scp local-source username@host:path/to/remote/dest
scp username@host:pub/csidata/GeneralAppFields_8_1_Feed.out path/to/local/dest && ls -l path/to/local/dest Timestamps on the retrieved file should match timestamps on the remote one.

ssh is of course secure shell. You can use it to grab files by using a pipe:
Code:
ssh -T username@host cd pub/csidata/ '&&' tar -cf - GeneralAppFields_8_1_Feed.out |
    tar -C path/to/destdir/ -xf -

will retrieve the GeneralAppFields_8_1_Feed.out file and extract it on your local machine, including proper timestamps.

Or, in general, you can just do the one command, the retrieval, and do the rest locally.

Sorry to labout this point but the above command will attempt to write a directory listing to file called pub/csidata/GeneralAppFields_8_1_Feed.out .

Code:
Use:
ls -l
Or:
ls pub/csidata/GeneralAppFields_8_1_Feed.out
Not:
ls -l pub/csidata/GeneralAppFields_8_1_Feed.out

Thanks Corona.
Now my heredoc is working fine.
Code:
Code:
 
/export/opt/SCssh/3.7.1_C0/bin/sftp -B - csi@192.168.1.100 <<FTP
lcd /WEBSERVER_LINK/data_logs/
ls pub/csidata/GeneralAppFields_8_1_Feed.out
get pub/csidata/GeneralAppFields_8_1_Feed.out
quit
FTP

Now I'm able to get files from FTP server.

You sure its working?
"-B" is for buffer size. You must use "-b".
