The prerequisite is to install expect package 2. The code is as follows: #! / bin/sh# master server password password=123456while read hostname; do expect-c "set timeout-1; spawn ssh-copy-id ${hostname}; expect {" * password:* "{send-- ${password}\ r; exp_continue;}" *\ (yes/no\) * "{send-- yes\ r; exp_continue;} eof {exit 0 }} "echo" hosts:$ {hostname} done. "# ipconf.cfg stores the ip of the user who wants to log in secret-free with the master server, for example: root@1921.68.245.134, the format of each line is the same as this example done < ipconf.cfgifconf.cfg example: root@192.168.6.132 root@192.168.6.133
