Bash腳本來推送ssh_keys

Question

我試圖讀取一個單獨的行上帶有大約500個服務器名稱的文件，然后對其中的每個ssh輸入ssh並為每個文件附加roots authorized_keys文件。 每次運行腳本和/或修改腳本時，都會不斷出現錯誤。 您能幫我找出問題所在嗎？ 我的操作系統是Mac OS X：

#!/usr/bin/expect
set timeout 60
set SERVERS "cat /Users/macuser/server.lst"
set USER "myuser"
set MY_PASS "mypasswordhere"

for EACH in $SERVERS; do
cat /Users/macuser/.ssh/id_rsa.pub | ssh $USER@$EACH "tee -a .ssh/authorized_keys"
expect {
    eof                          {break}
    "The authenticity of host"   {send "yes\r"}
    "password:"                  {send "$MY_PASS\r"}
    }

interact
done

這是錯誤：

wrong # args: should be "for start test next command"
while executing
"for EACH in $SERVERS"
(file "./keyssh_push.sh" line 7)

從使用bash腳本中的 sshpass 為SSH命令提供密碼中 ， sshpass看起來是最簡單的方法。 我會做：

#!/bin/sh
servers=`cat /Users/macuser/server.lst`
user="myuser"
my_pass="mypasswordhere"

for server in $servers
do
  </Users/macuser/.ssh/id_rsa.pub sshpass -p"$my_pass" \
    ssh -o StrictHostKeyChecking=no $user@$server cat '>>.ssh/authorized_keys'
done

更新

隨着@alvits的建議：

#!/bin/sh
servers=`cat /Users/macuser/server.lst`
user="myuser"
my_pass="mypasswordhere"

for server in $servers
do
  sshpass -p"$my_pass" ssh-copy-id -o StrictHostKeyChecking=no \
    -i /Users/macuser/.ssh/id_rsa $user@$server
done
