Append has prefix in while loop

Shell Programming and Scripting
1

I was using below script to grep one file. I need to append the output using prefix

Data of all-Vms-1.txt

server-1 frame-1 LUN001
server-2 frame-1 LUN002

Data of all-vm-unix.txt

server-1     24
server-2     50

Script used

while read -r g h ;
do
cat all-Vms-1.txt |grep -i $g |awk '$0="frame "$0'|sed -e "s/frame/${g} ${h}/" >> all-vm-unix-with-vc-2

done < all-vm-unix.txt

I need output like this

server-1 24 server-1 frame-1 LUN001
server-2 50 server-2 frame-1 LUN002

But Now it was echo in next line

server-1 24 
server-1 frame-1 LUN001
server-2 50 
server-2 frame-1 LUN002

the usual approach:

awk 'FNR==NR {f1[$1]=$0;next} $1 in f1 {print $0, f1[$1]}' all-Vms-1.txt all-vm-unix.txt

Hi vgersh99

I think it was checking case sensitive and ignore if it dont match. How to ignore case sensitive

4

Use the tolower(str) function to changes strings to lowercase where appropriate to make it case insensitive...

Sorry where i need to use this code

To adjust vgersh99's suggestion try:

awk '{i=tolower($1)} FNR==NR {f1[i]=$0;next} i in f1 {print $0, f1[i]}' all-Vms-1.txt all-vm-unix.txt
