• A 機器執行腳本

[root@aminglinux-02 sbin]# ./2.expect
-bash: ./2.expect: 權限不夠
[root@aminglinux-02 sbin]# chmod a+x 2.expect
[root@aminglinux-02 sbin]# ./!$
./2.expect
spawn ssh root@192.168.133.130

[root@aminglinux-01 ~]# touch /tmp/12.txt
[root@aminglinux-01 ~]# echo 1212 > /tmp/12.txt

• B機器查看腳本運行的命令是否成功

[root@aminglinux-01 ~]# ls /tmp/
12.txt      systemd-private-7723d189c8d3469ab732edadbbc340cb-nginx.service-eKHAIK
mysql.sock  systemd-private-7723d189c8d3469ab732edadbbc340cb-vmtoolsd.service-1yxB4M
