1，写一个循环，ping整个子网的ip。

使用while循环

#!/bin/bash

ip=223

while [ "$ip" -ne "239" ]

ping 121.201.0.$ip -c1 && echo "121.201.0.$ip yes" >> ip_list.txt || echo "121.201.0.$ip no" >> ip_list.txt

((ip+=1))

done

使用for循环(推荐)

#!/bin/bash

for ip in 192.168.1.{100..255}

ping $ip -c 1 && echo $ip yes >> ./check_ip_network.txt|| echo $ip no >> ./check_ip_network.txt

done

2, 9*9乘法表

#!/bin/bash

for a in {1..9}
do
        for b in {1..9}
        do
                [ $a -ge $b ] && echo -en "$a x $b = $(expr $a \* $b) "
        done
echo ""
done

[root@shell shell]# sh 9x9.sh
1 x 1 = 1
2 x 1 = 2 2 x 2 = 4
3 x 1 = 3 3 x 2 = 6 3 x 3 = 9
4 x 1 = 4 4 x 2 = 8 4 x 3 = 12 4 x 4 = 16
5 x 1 = 5 5 x 2 = 10 5 x 3 = 15 5 x 4 = 20 5 x 5 = 25
6 x 1 = 6 6 x 2 = 12 6 x 3 = 18 6 x 4 = 24 6 x 5 = 30 6 x 6 = 36
7 x 1 = 7 7 x 2 = 14 7 x 3 = 21 7 x 4 = 28 7 x 5 = 35 7 x 6 = 42 7 x 7 = 49
8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64
9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 9 x 6 = 54 9 x 7 = 63 9 x 8 = 72 9 x 9 = 81

3. shell跳板机(触发信号后屏蔽信号)

方法1:

1）首先做好ssh key验证，做ssh key免登陆验证

2）实现传统的远程连接菜单选择脚本

3）利用linux信号防止用户在跳板机上操作。

4）用户登陆后既调用脚本。

代码如下：

[root@shell practical_script]# cat tiaoban.sh
#!/bin/bash

# function
function trapper ()
{
        trap ‘:‘ INT EXIT TSTP TERM HUP
}
while :
do
        trapper
                clear
                        cat <<menu
# This is a springboard machine, can only be through the springboard
# machine landing the following system.

        Please select the server you want to log on:

                                1) link 126.201.20.132(TT3)
                                2) exit
menu

read -p "pleas select: " num
case "$num" in
        1)
                echo "126.201.20.132(TT3) landing ..."
                ssh -p 26333 xxllen@126.201.20.132
                ;;
        2|*)
                exit
                ;;

esac

done

方法2： root链接服务器，expect 每次重新建立ssh key
