Automate ssh connection with expect?

Question

bash

There is a bash script that, under certain conditions, must connect via ssh to different hosts and take files from them. To automate this process, a function was created in the script to connect with expect.

SSH1() {
#Список хостов:
HOSTS=$(cat /home/ip.txt | grep "client-$num" | awk '{print $2}')
#Команды для expect:
COMM="
#Соедиение ssh:
spawn scp -r [email protected]$HOSTS:/home/client/ /etc/openvpn/keys/
expect \"*(yes/no)?*\" {send \"yes\r\"}
expect \"Password:\"
send \"$PASSWD\r\"
#Завершение выполнения expect:
expect eof
"
#Запуск expect с набором команд:
expect -c "$COMM"
}

After the files have been taken from the host, you need to check these files and run a couple more commands.
But all commands that are after this function are displayed in the console with a "+" at the beginning and are not executed. I understand that expect perceives them as its own commands. How to fix it?

Answer 1

Why do you need an exp?
Authorization in ssh with passwords is the last century.
Set up SSH keys and just scp without passwords.
