Power Help with Ping Script and AWK
Hey Guys,

First time posting here. I keep getting back here on my google searches to help me in my scripting quest.
Can i ask for some guidance please?

I acquired a script, from these forums in fact that pings a list of IPs/Hostnames. Works a treat. Echos results to a file with the value (IP/Hostname) pinged.

Before
Code:
device1      1.1.1.1
device2      2.2.2.2

Script
Code:
#! /bin/sh
IPLIST=`less ./devices.txt | awk '{print $2}'`
for ip in $IPLIST
do
  echo $ip
  ping -c 2 $ip >>device-log.txt
  if [ $? -eq 0 ]
  then
     echo $ip "PINGS">>pingresultsace-device.txt
  else
    echo $ip "DOESN'T PING">>pingresultsace-device.txt
 fi
done


The output is
Code:
1.1.1.1 PINGS
2.2.2.2 DOESN'T PING

What i would really like is to put the entire line, or parts of it to produce. By parts of it i mean, using the AWK command or similar to select the fields to echo.

Code:
device1      1.1.1.1 PINGS
device2      2.2.2.2 DOESN'T PING

Thanks All

Maybe something like this?
Code:
#! /bin/sh

while read host ip
do
  echo $ip
  ping -c 2 $ip >>device-log.txt
  if [ $? -eq 0 ]
  then
    echo $host $ip "PINGS">>pingresultsace-device.txt
  else
    echo $host $ip "DOESN'T PING">>pingresultsace-device.txt
  fi
done < ./devices.txt

PERFECT !!! Smilie

I did try the while read line, but was getting no where.

Can you tell me how this, using host and ip gets the column information.
i.e. suppose there was more columns?

Thanks for the fast reply

Excerption from the man page of sh:

Quote:
read [-p prompt] [-r] variable [...]

The prompt is printed if the -p option is specified and the stan-
dard input is a terminal. Then a line is read from the standard
input. The trailing newline is deleted from the line and the line
is split as described in the section on word splitting above, and
the pieces are assigned to the variables in order. At least one
variable must be specified. If there are more pieces than vari-
ables, the remaining pieces (along with the characters in IFS that
separated them) are assigned to the last variable. If there are
more variables than pieces, the remaining variables are assigned
the null string. The read builtin will indicate success unless
EOF is encountered on input, in which case failure is returned.

By default, unless the -r option is specified, the backslash "\"
acts as an escape character, causing the following character to be
treated literally. If a backslash is followed by a newline, the
backslash and the newline will be deleted.
