nslookup to use /etc/hosts in LINUX

Hi

In LINUX nslookup is always using BIND for
hostname resolution. Anybody know how to override this with /etc/hosts

Thanks

edit the file /etc/nsswitch.conf
come to the line:
dns files (it can in defferent order)
and change it to:
files dns
This will cause the search order to be first in /etc/hosts and then in DNS.If you wish to eliminate search in DNS remove "dns" from this line.

AFAIK, nslookup is always uses DNS;
for getting info from /etc/hosts you may use getent utility.

See "Getting an entry with getent?http://www.itworld.com/Comp/3380/nls_unixgetent041202/index.html for more.
