Нижче - сценарій.
Я хотів увійти в декілька серверів і перевірити наявність 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 б очікував, що вихід буде такий, як ..
server1_hostname
kernel_version
server2_hostname
kernel_version
і так далі..
Я запустив цей сценарій із близько 80 серверів у server.txt
І вихід, який я отримав, був як .....

Тут я отримав вихід лише для одного хоста, який є, xxxxdev01
і це теж постачається з банером ssh та іншими попередженнями.
Мені потрібен вихід усіх інших хостів і без ssh банера. Що тут не так?
ssh -t -t root@
..., щоб примусити псевдотермінал.
sshpass -p password root@server histname
?
