I have tested it in a dummy file. It needs to be run as root. If you have static entries, you need to add them into the script or you will lose them. #!/bin/bash # this ONLY WORKS IF there are no other entries in hosts!! # it will overwrite anything in the hosts file! HOSTS="/etc/hosts" TEMP_HOSTS="/tmp/hosts.tmp" NIC="eth0" IP="`ifconfig $NIC | grep inet | cut -d : -f 2 | cut -d \ -f 1`" FULL_NAME="`uname -n`" SHORT_NAME="`uname -n|cut -d. -f1`" echo "127.0.0.1 localhost.localdomain localhost" > $TEMP_HOSTS echo "$IP $FULL_NAME $SHORT_NAME" >> $TEMP_HOSTS # add more static entries if needed like this: #echo "xxx.xxx.xxx.xxx somehost.domain.com somehost" >> $TEMP_HOSTS cat $TEMP_HOSTS > $HOSTS #end Hope that helps -- Pete Nesbitt, rhce -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
