通过expect实现自动远程登陆的模板
-
学会在shell脚本执行时读取密码而不是把密码直接赋值给一个变量
read -p "Your Passwd: " -s PASSWARD #变量PASSWARD存放输入的密码 -
在shell中插入使用expect
expect<<EOF
...
#expect codes...
EOF -
expect自动登陆不退出
set timeout 10 #timeout is 10s
spawn ssh $USER@$SERVER
expect {
"(yes/no)?"
{
send "yes\n"
expect "assword:" { send "$PASSWARD"}
}
"assword:"
{
send "$PASSWARD"
}
}
interact -
expect自动登陆执行指定命令并退出
spawn ssh $USER@$SERVER
expect {
"(yes/no)?"
{
send "yes\n"
expect "assword:" { send "$PASSWARD"}
}
"assword:"
{
send "$PASSWARD"
}
}
expect "# "
send "$YOUR_CMD\n"
expect "$EXPECT_PRINTS"
send "exit\n"
expect eof
