How to find out the format?
type man 5 hosts in terminal
why 5?
5 is the section number of a man page, it means file formats
ref:http://en.wikipedia.org/wiki/Man_page
Extra:
The etc/hosts file specifies the hostname or computer name your current shell is running.
In my case, my computer name is zhang-laptop and my login name is zhang, so my bash looks like:
zhang@zhang-laptop:~$
And my etc/host file is:
zhang@zhang-laptop:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 zhang-laptop
#added
#127.0.0.2 domainhound
#127.0.0.2 zhangmichael.com
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
how do you file the hosts file format?
