要解决的是每次都要输入密码，所以不能后台投递任务。

解决方案：

核心是expect

　　   spawn

#!/usr/bin/expect -f


set timeout 10
set username [lindex $argv 0]
set password [lindex $argv 1]
set host [lindex $argv 2]
set src_file [lindex $argv 3]
set dest_file [lindex $argv 4]

spawn rsync -avtp $src_file $username@$host:$dest_file
expect {
"(yes/no)?"
{
send "yes\n"
expect "*assword" { send "$password\n"}
}
"*assword"
{
send "$password\n"
}
}
expect "100%"
expect eof

#!/usr/bin/expect -f


set timeout 10
set username [lindex $argv 0]
set password [lindex $argv 1]
set host [lindex $argv 2]
set src_file [lindex $argv 3]
set dest_file [lindex $argv 4]

spawn rsync -avtp  $username@$host:$src_file $dest_file
expect {
"(yes/no)?"
{
send "yes\n"
expect "*assword" { send "$password\n"}
}
"*assword"
{
send "$password\n"
}
}
expect "100%"
expect eof
