Shell Check Company surviving PC

If the leader tells you to check the company when you're off duty. Those PCs are open, one to see? NO, it's too much trouble. The following script can quickly find the surviving PC through the ICMP ping packet, it is important to note that the local host will be the same as the subnet mask of the target host, and also at the same address bit.

#!/bin/bash

Read-p "Please enter start IP:" bigin_ip

Read-p "Please enter end IP:" over_ip

Ip_net= ' echo $bigin _ip|cut-d. -F 1-3 '

B_num= ' echo $bigin _ip|cut-d. -F 4 '

O_num= ' echo $over _ip|cut-d. -F 4 '

Echo $ip _net

Echo $b _num

Echo $o _num

For i in ' SEQ 1 3 '

Do

For b_cut in ' Echo $bigin _ip| Cut-d. -F $i '

Do

for O_cut in ' Echo $over _ip|cut-d. -F $i '

Do

If [$b _cut-ne $o _cut]

Then

echo "Please enter IP of the same address bit"

Else

While [$b _num-le $o _num]

Do

Ping-c 2-i 0.2 $ip _net. $b _num &>/dev/null

If [$? = 0]

Then

echo "$ip _net. $b _num is Alive"

Fi

Let b_num++
