Your requirements are very thin. But since you are using Linux, if you have a file myhosts.txt that looks like this: 10.9.6.91 fred fred.com 10.9.6.92 nails nails.com 10.9.6.43 jim jim.com 10.9.6.81 lester lester.com The IP address is the first field. You can write a small bash script that grabs the field and prints it: #!/bin/bash while read ipadd f2 f3 do echo $ipadd done < myhosts.txt
