UNIX for Dummies Questions & Answers

Hello All,
I have an issue with sftp in BatchMode option. I am using the below command to sftp a file in ssh2 from a script.

sftp -o BatchMode=yes userid@servername <<EOF
cd /ftp/cds
put quotes.csv
quit
EOF

But the connection doesnt returns back from sftp and it just hangs in the connected mode forever. I had to terminate the program to exit the connection. Can someone please advise how can i resolve the issue ?

Thanks,
Sateesh

Does the sftp gets successfully connected or not ? Wrap the whole thing in a expect script, get the return status with simple "if" - there are many examples in the forum.

The connection actually establishes bet it doesnt come back and i had to kill the job explecitly.
Can u please refer me some examples to avoid this issue. Is there is any other option other than -B option

Why not :
specify -b flag, add the same commands in a file, enter the path to it, and see if it happens.
Otherwise in expect :

Code:

#!/usr/bin/expect

set timeout 10

if { $argc != 3 } {
    puts "Usage $argv0 host user pass "
    exit 1
}

set host [lindex $argv 0]
set user [lindex $argv 1]
set pass [lindex $argv 2]

spawn sftp -o Port=22 $user@$host
expect *assword:

send "$pass\r"
expect sftp>

send "$your-command-here\r"
expect sftp>

send "exit\r"
expect eof

With this generic script, you can specify the timeout to be 10 seconds.
