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
