❶ shell 腳本。自動安裝軟體，遇到要輸入yes怎麼自動輸入，不用人為介入
使用expect 下的spawn命令：
如：
expect << EOF
set timeout 5
spawn ssh -l $hostuser $hostaddr
expect {
"yes/no)?" { send "yes\r";exp_continue }
"assword:" { send "$passwd\r" }
}
expect "$hostuser*"
send "ssh-keygen -t rsa\r"
expect "Enter file in which to save the key*"
send "\r"
expect {
"(y/n)?" { send "n\r";exp_continue }
"Enter passphrase*" { send "\r";exp_continue }
"Enter same passphrase again:" { send "\r" }
}
interact
EOF
❷ linux下編寫一個shell腳本，實現自動安裝軟體
Linux下Oracle的自動安裝腳本，基本上就是yes和no

❸ 用shell腳本怎麼實現安裝升級版本
A：本腳本運行的機器，Linux
B：待安裝JDK的機器, Linux
首先在腳本運行的機器A上確定可以ssh無密碼登錄到待安裝jdk的機器B上，然後就可以在A上運行本腳本:
復制代碼 代碼如下:
$ ./install-jdk.sh B的IP
or:
復制代碼 代碼如下:
$ ./install-jdk.sh "B的IP" "JDK的URI"
就可以在機器B上安裝JDK。jdk使用的tar包需要用戶自己設定DEFAULT_JDK_SRC=？，保證可以wget得到即可。下面是全部腳本內容：
復制代碼 代碼如下:
#!/bin/bash
#
# @file
# install-jdk.sh
#
# @date
# 2013-12-19
#
# @author
# cheungmine
#
# @version
# 0.0.1pre
#
# @usage:
# ./install-jdk.sh 192.168.122.206
