通過expect實現(xiàn)自動遠(yuǎn)程登陸的模板
學(xué)會在shell腳本執(zhí)行時讀取密碼而不是把密碼直接賦值給一個變量
read -p "Your Passwd: " -s PASSWARD #變量PASSWARD存放輸入的密碼在shell中插入使用expect
expect<<EOF
...
#expect codes...
EOFexpect自動登陸不退出
set timeout 10 #timeout is 10s
spawn ssh $USER@$SERVER
expect {
"(yes/no)?"
{
send "yes\n"
expect "assword:" { send "$PASSWARD"}
}
"assword:"
{
send "$PASSWARD"
}
}
interactexpect自動登陸執(zhí)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
