Ниже приведен сценарий.
Я хотел войти на несколько серверов и проверить версию ядра.
#!/bin/bash
#input server names line by line in server.txt
cat server.txt | while read line
do
sshpass -p password ssh root@$line << EOF
hostname
uname -r
EOF
done
Я ожидаю, что выходной, который идет как ..
server1_hostname
kernel_version
server2_hostname
kernel_version
и так далее..
Я запустил этот скрипт с около 80 серверов в server.txt
И результат, который я получил, был как .....

Здесь я получил вывод только для 1 хоста, который xxxxdev01
также поставляется с баннером ssh и другим предупреждением.
Мне нужен вывод всех других хостов и без ssh-баннера .. Что здесь не так?
ssh -t -t root@
..., чтобы вызвать псевдо-терминал.
sshpass -p password root@server histname
