thanks. I got how to do this one. I got another questio in the process. when I code "s/^is$/are/g" , this will look for 'is; in the beginning and at the end of string. So if I have
<code> Apache is a modular server. This implies that only the most basic functionality is included in the core server. is it so ? Extended features are available through modules which can be loaded into Apache. By default, a base set of modules is included in the server at compile-time. If the server is compiled to use dynamically loaded modules, then modules can be compiled separately and added at any time using the LoadModule directive. Otherwise, Apache must be recompiled to add or remove modules. Configuration directives may be included conditional on a presence of a particular module by enclosing them in an <IfModule> block<code>
is this will not change anything in the file.
