linux + create host file from CSV file by sed or awk or perl

Question

I have the following CSV file

this file defined which Linux machine exist in the system and there ip's

my target is to create host file from this file

please advice how to create host file as example 1 from my CSV file ( I need to match the IP address from CSV file and put it on the first field of the host file , then match the LINUX name and locate this name in the sec field – as example 1 )

remark - should be performed by sed or awk or perl .. , I need to write the solution in my bash script

CSV file

 , machine , VM-LINUX1 , SZ , Phy , 10.213.158.18 , PROXY , VM-LINUX2 , SZ , 10.213.158.19 , OLD HW , VM-LINUX3 , SZ , 10.213.158.20 , , VM-LINUX4 , SZ , Phy , 10.213.158.21 , , VM-LINUX5 , SZ , Phy , OUT , EXT , LAN3 , 10.213.158.22 , INTERNAL , VM-LINUX6 , SZ , Phy , 10.213.158.23 , , server , new HW , VM-LINUX7 , SZ , Phy , 10.213.158.24 , OUT, LAN3 , VM-LINUX8 , SZ , 10.213.158.25 , OLD HW , machine , VM-LINUX9 , SZ , Phy , INT , 10.213.158.26 , LAN2, AN45, , VM-LINUX10 , SZ , Phy , 10.213.158.27 , , VM-LINUX11 , SZ , Phy , LAN5 , 10.213.158.28 , 

example 1 ( host file )

 10.213.158.18 VM-LINUX1 10.213.158.19 VM-LINUX2 10.213.158.20 VM-LINUX3 10.213.158.21 VM-LINUX4 10.213.158.22 VM-LINUX5 10.213.158.23 VM-LINUX6 10.213.158.24 VM-LINUX7 10.213.158.25 VM-LINUX8 10.213.158.26 VM-LINUX9 10.213.158.27 VM-LINUX10 10.213.158.25 VM-MACHINE8 10.213.158.26 STAR9 10.213.158.27 TOP10 10.213.158.28 SERVER11 

Answer 1

cat file | perl -ne '/(\w+-LINUX\w+).*\s([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})/;print "$2 $1\n";'

Answer 2

perl -ne 'print "$1 $2\n" if m/(VM-LINUX\d+).*(\d+\.\d+\.\d+\.\d+)/;' < /PATH/TO/your.csv 

or (if not even the order of the two fields is determined)

perl -ne 'print "$1 " if m/(VM-LINUX\d+)/; print "$1" if m/(\d+\.\d+\.\d+\.\d+)/; print "\n";' < /PATH/TO/your.csv
