Shell Programming and Scripting

I have FTP function:

Code:

FTPfunction ()
{
integer sw=4
ftp -niv <<- !  > $FTPLOG 2>&1
open $1
user $2
$3
put /tmp/ptdata.csv
close
bye
!

but, I need to use sFTP and port 22.
Can you please let me know how to modify FTPfunction I have?

Please advise. Thank you!!

As you provided the code:

Code:

FTPfunction ()
{
integer sw=4
sftp -niv <<- !  > $FTPLOG 2>&1
open ${1}:22
user $2
$3
put /tmp/ptdata.csv
close
bye
!
}

hth

sftp by default connects to port 22 on the remote host. I'm not sure about the :22 part of the answer above ...on connecting to my sftp server it causes problems.

Also the -niv parameters are not valid for sftp.

Password authentication is also an issue - if you need to automate sftp connections you should setup non-interactive ssh sessions first. Once you have that your function could be:

Code:

FTPfunction ()
{
integer sw=4
sftp -b - ${2}@${1} <<- !  > $FTPLOG 2>&1
put /tmp/ptdata.csv
quit
!
}

or simply:

Code:

FTPfunction ()
{
  scp -B /tmp/ptdata.csv ${2}@{$1}: > $FTPLOG 2>&1
}

As Chubler_XL says, you need to sort out authentication. I don't believe you can use sftp with a here document to include the credentials. You could write an expect script, but it is so much effort and degrades the security that sftp is enforcing.

You can also use sftp in 'batch' mode, in that it will read a command file. Your main script could then end up as something like this:-

Code:

sftp -b $command_file $user@$server

The contents of the command file would be the commands you would require, e.g. cd, put etc.

Errors in this process will cause a non-zero return code from sftp which is far easier to test than reading the output from a normal ftp with the -v flag. It's very easy in shell script and more complex in expect so there's another reason to avoid that.



I hope that this helps,
