Does this do what you want? But - this will output all modified files to stdout; correct redirections may not be that easy to find.
My bad, still its not get substituting, I used below one
Code:
find /tmp -type f -exec sed 's/HOSTNAME=`hostname`/HOSTNAME=localhost/g' {} \;

Please wrap all code, files, input & output/errors in CODE tags.
It makes it easier to read and preserves spaces for indenting or fixed-width data.

HOSTNAME(5)							   /etc/hostname						       HOSTNAME(5)

NAME
hostname - Local host name configuration file SYNOPSIS
/etc/hostname DESCRIPTION
The /etc/hostname file configures the name of the local system that is set during boot, with the sethostname(2) system call. It should contain a single newline-terminated host name string. The host name may be a free-form string up to 64 characters in length, however it is recommended that it consists only of 7bit ASCII lower-case characters and no spaces or dots, and limits itself to the format allowed for DNS domain name labels, even though this is not a strict requirement. Depending on the operating system other configuration files might be checked for configuration of the host name as well, however only as fallback. HISTORY
The simple configuration file format of /etc/hostname originates from Debian GNU/Linux. SEE ALSO
