Poniżej znajduje się skrypt.
Chciałem zalogować się do kilku serwerów i sprawdzić wersję jądra.
#!/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
Oczekiwałbym produkcji, która idzie jak ...
server1_hostname
kernel_version
server2_hostname
kernel_version
i tak dalej..
Uruchomiłem ten skrypt z około 80 serwerami w server.txt
A wynik, który uzyskałem, był jak .....

Tutaj otrzymałem dane wyjściowe tylko dla 1 hosta, który również jest xxxxdev01
dostarczany z banerem ssh i innym ostrzeżeniem.
Potrzebuję danych wyjściowych wszystkich innych hostów i bez bannera ssh. Co się tutaj dzieje?
ssh -t -t root@
..., aby wymusić pseudoterminal.
sshpass -p password root@server histname
