Do ping cycle test through shell script under Mac OS

Do ping cycle test through shell script

System environment:

Operating system: MAC OS

An interesting and useful system maintenance script that tests the connectivity of network hosts through shell script:

[tiany@localhost ~] $cat ping.sh

#! / bin/bash

For i in `seq 254`

Do

Ip=192.168.1.$i

Ping-C1 $ip > / dev/null 2 > & 1

[$?-eq 0] & & echo "$ip is alive" | | echo "$ip is not alive"

Done

[tiany@localhost ~] $sh ping.sh

192.168.1.1 is alive

192.168.1.2 is not alive

192.168.1.3 is not alive

192.168.1.4 is not alive

192.168.1.5 is not alive

192.168.1.6 is not alive

Transfer to another:

Use shell script to implement all hosts in the ping network segment:

#! / bin/sh

# ping all host

# edit by www.jbxue.com

# find from / etc/hosts for host info,and filter IP address

Cat / etc/hosts | grep-v ^ # | grep-v ^ $| while read LINE

Do

For M in `awk'{print $1}'`

Do

If ping-w 1-c 1$ M | grep "100%" > / dev/null

Then

Echo "$M is down"

Else

Echo "$M is up"

Fi

Done

Done
