Linux Shell脚本实现自动交互

方法一：（以OpenSSH编译完成之后的 拷贝和生成key 为例）

#!/bin/bash

DIR_PATH=$HOME/sshdfile

cp sshd $DIR_PATH/sbin

cp scp sftp ssh ssh-add ssh-agent ssh-keygen ssh-keyscan $DIR_PATH/bin
cp sftp-server ssh-keysign $DIR_PATH/libexec
cp sshd_config ssh_config $DIR_PATH/etc

chmod 755 $DIR_PATH/var/empty

ssh-keygen -t rsa1 -f ssh_host_key -N "" << EOF
y
EOF

ssh-keygen -t rsa -f ssh_host_rsa_key -N "" << EOF
y
EOF

ssh-keygen -t dsa -f ssh_host_dsa_key -N "" << EOF
y
EOF

cp ssh_host_* $DIR_PATH/etc

方法二：（以FTP用户自动登录为例）

#!/usr/bin/expect
set file [lindex $argv 0];
set timeout -1;
spawn ftp 192.168.1.***
expect "Name"
send "username***\r"
expect "Password"
send "passwd***\r"
expect "ftp>"
send "hash\r"
expect "*ftp>*"
send "put $file\n"
expect "*ftp>*"
send "bye\r"
expect "*Goodbye*"
expect eof
exit
