A crudely cobbled solution written in less than 5 lines.

!Please! be careful with its use.  ;-) 

The script takes 3 items from the command line and changes all items 
specified first with items specified second in the file specified third

ex call: quickhack 192.168.0 10.1.1 /etc/hosts 

The example above would change all 192.168.0 with 10.1.1 in /etc/hosts

perl -pi -e "s/$1/$2/g" $3

Do with it as you will.
