脚本内容为:
#!/usr/bin/expect set timeout -1 spawn scp /data/aaa_557_data.tar root@10.66.1.43:/data/ expect { "password" {send "abc123 ";} "yes/no" {send "yes";exp_continue} } interact
执行脚本:
/usr/bin/expect aa.exp
报错信息为:
spawn scp /data/aa_557_data.tar root@10.66.1.43:/data/
Warning: Permanently added '10.66.1.43' (RSA) to the list of known hosts.

while executing
"interact"
(file "scp_script.ex" line 8)
报错原因:因为源机器能免密码登录目标机器,而上面的脚本中,是需要询问密码且回答yes或no才能登录的,
所以执行脚本时,导致了错误。
修复办法:删除目标机器中~/.ssh/authorized_keys中的关于源机器的信息。
