Output not coming as desired.

Hi guys.

I have a file containing some hosts and their IPs.

Code:
host host1 192.168.2.10
host host2 192.168.2.11
host host3 192.168.2.12

I am writing a script where I want to print these values in 1 line. My script looks like

Code:
RUNTIME_NODE=`cat hosts.properties | grep host`

for i in $RUNTIME_NODE
do
        echo $i | awk '{ print $1  $2 $3 }'
done

The output I am expecting is:

Code:
host host1 192.168.2.10

host host2 192.168.2.11

host host3 192.168.2.12



But the result I am getting is:

Code:
host 
host1 
192.168.2.10
host 
host2 
192.168.2.11
host 
host3 
192.168.2.12

How can I fix this ?

To double space the file:
Code:
sed G FILE

Not quite following,

why not?

Code:
grep host hosts.properties | awk '{print $0"\n"}'

or simply

Code:
awk '/host/{print $0"\n"}'

Why not
Code:
 awk '/host/{print $0"\n"}' host.properties

or in sed
Code:
 sed '/host/!d;G' host.properties

Of course there is no need to match a pattern if the file only needs double spacing.

Hi guys,

The issue is that I have 2 colums and I have to run 1 for loop for comparision purposes.

Column 1 contains

host1
host2
host3

Columns 2 contains

192.168.2.10
192.168.2.11
192.168.2.12

Combined file is:

host1 192.168.2.10
host2 192.168.2.11
host3 192.168.2.12

Now I ahve to run 1 for loop but I need 2 variables under that for loop. One variable takes first column and second variable takes second column RESPECTIVELY.

How can I do that ?
