Question Open and System command in SFTP
Hi Unix team,
Is there any alternative option and command which one can use in ftp for sftp usage.

open, system command --> alternative for sftp usage
-n option --> alternative for sftp usage
sftp supports only binary transmission.
how one can achieve ascii mode file transmission in sftp.

example:
can i use code like this:
Code:
sftp -b /dev/stdin -v <<EOF
open remoteserver
system
put localfile remotefile
quit
EOF

then try ftp client..
Code:
ftp localhost
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ascii
200 Switching to ASCII mode.
ftp>

As for as i know sftp does not yet support other than binary mode. maybe thinking is not needed this.
because in unix/linux to unix/linux (same) systems file transfer issue is not problem.

you can try like this
Code:
sftp localhost -b </dev/stdin <<EOF
put localfile remotefile
quit
EOF

Hi ygemici,

Thanks for your reply.

i have to use sftp only. so for ascii mode transfer alone i cant use ftp.

The code which you have mentioned ,
Code:
sftp localhost -b </dev/stdin <<EOF

is it in correct syntax.I dont think so. why do we need to mention localhost.
Moreover my Question is 'can one use Open command in sftp?' because in man page of sftp ,open command is not present.

Please help anyone.

Hi

I just test for localhost..however you can use any IP that you want to connect host.
And syntax is seem correct for localhost and did you try?
open command is not use in sftp..because of this i use IP (in my example as localhost)
in binary mode you can transfer binary and text files without any corruption (or interpretation problem) for unix-to-unix systems.
and sftp only uses SSH 2 protocol so remote host must support this.
what is your goal?

Look at lftp - a client that understands ftp, sftp, fish and http protocols and can be scriptable. You can specify ASCII transfers and I think it's possible under the sftp protocol.

If you use Linux it may be in your repositories. If not you will need to compile & install it.

Hi ygemici,

Thanks for your reply. Sorry for the late reply.
my goal is , i need to transfer file from unix to webmethods installed Linux/unix system. And what about system command.? in sftp.
Using Openssh i need to do these file transfer.
Do i need to call ssh program before calling sftp or internally it ll happen (when using shell script) like this:
Code:
#The below has declared in config file and i am using shell script for file transfer.
#path=usr/bin/ssh
#sftppath=usr/bin/sftp
#remoteaddress=user@remotehost
$path remoteIP
$sftppath -b /dev/fed/0 -v  $remoteaddress<<endsftp
filetransfer code...
endsftp

if any error on this state your reply with code example.

Thanks in advance.

Hi
why do you want to make sftp via use ssh command?
sftp does it already Smilie

did you try your code ? your batch file is in /dev/fed/0 ?
Code:
-b /dev/fed/0

you can try this simple script Smilie
Code:
remoteadr=user@remotehost
sftp $remoteadr << EOF
filetransfer code...
quit
EOF
