This may not be what you are looking for.. These are options i could think of.

1> You can use public key authentication which doesn't require user/password authentication.
2> use expect if you have it available
3> use NET::SFTP you do the job and call it from shell script.

#!/usr/bin/expect
 
spawn sftp username@host
expect "assword:"
send "your_password\n"
expect "sftp>"
send "your command here\n"
expect "sftp>"
send "quit\n"

How about this ?


 
use Net::SFTP;
my %parameters;

open ( my $INP, "<", "config.txt" );
while( <$INP> ) {
my ( $key, $value ) = split/:/;
$parameters { $key } = $value;
}

my $sftp = Net::SFTP->new($host, %parameters);

Open in new window


config.txt
user: ABC
password: XXXX

If that is the case use perl and build expect script in the above email and run it from perl with system command.
If you have expect( /usr/bin/expect ) i think you could do it.
