cygwin - bash script to read/ping a list of ip addresses from a text file and then write the results to another file? -

i have text file lists of ip addresses called address.txt contains following

172.26.26.1   wlan01  172.26.27.65    wlan02  172.26.28.180    wlan03 

i need write bash script reads ip addresses, ping them , output text file this:

172.26.26.1 up

172.26.27.65 down

172.26.28.180 down

i new bash scripting not sure start this. appreciated.

in linux work:

awk '{print $1}' < address.txt | while read ip; ping -c1 $ip >/dev/null 2>&1 && echo $ip || echo $ip down; done 

i don't have cygwin test, should work there too.

explanation:

• with awk first column input file , pipe loop
• we send single ping $ip, , redirect standard output , standard error /dev/null doesn't pollute our output
• if ping successful, command after && executed: echo $ip up
• if ping fails, command after || executed: echo $ip down

somewhat more readable, expanded format, put in script:

#!/bin/sh awk '{print $1}' < address.txt | while read ip;     if ping -c1 $ip >/dev/null 2>&1;         echo $ip     else         echo $ip down     fi done
