Insert a line including Variable & Carriage Return / sed command as Variable
I want to instert Category:XXXXX into the 2. line

something like this should work, but I have somewhere the wrong sytanx. something with the linebreak goes wrong:

sed "2i\\${n}Category:$cat\n"

Sample:

Titel Blahh Blahh abllk sdhsd sjdhf
Blahh Blah Blahh
Blahh

Should look like this afterwards;

Titel Blahh Blahh abllk sdhsd sjdhf
Category:The Blahh
Blahh Blah Blahh
Blahh

2. Question: how should the syntax be, if the sed command itself should be a variable, like:

insertcat="sed "2i\\${n}Category:$cat\n""

module::find5.18

Find(3) 						User Contributed Perl Documentation						   Find(3)

NAME

       Module::Find - Find and use installed modules in a (sub)category

SYNOPSIS

	 use Module::Find;

	 # use all modules in the Plugins/ directory
	 @found = usesub Mysoft::Plugins;

	 # use modules in all subdirectories
	 @found = useall Mysoft::Plugins;

	 # find all DBI::... modules
	 @found = findsubmod DBI;

	 # find anything in the CGI/ directory
	 @found = findallmod CGI;

	 # set your own search dirs (uses @INC otherwise)
	 setmoduledirs(@INC, @plugindirs, $appdir);

	 # not exported by default
	 use Module::Find qw(ignoresymlinks followsymlinks);

	 # ignore symlinks
	 ignoresymlinks();

	 # follow symlinks (default)
	 followsymlinks();

DESCRIPTION

       Module::Find lets you find and use modules in categories. This can be very useful for auto-detecting driver or plugin modules. You can
       differentiate between looking in the category itself or in all subcategories.

       If you want Module::Find to search in a certain directory on your harddisk (such as the plugins directory of your software installation),
       make sure you modify @INC before you call the Module::Find functions.

FUNCTIONS

       "setmoduledirs(@directories)"
	   Sets the directories to be searched for modules. If not set, Module::Find will use @INC. If you use this function, @INC will not be
	   included automatically, so add it if you want it. Set to undef to revert to default behaviour.

       "@found = findsubmod Module::Category"
	   Returns modules found in the Module/Category subdirectories of your perl installation. E.g. "findsubmod CGI" will return
	   "CGI::Session", but not "CGI::Session::File" .

       "@found = findallmod Module::Category"
	   Returns modules found in the Module/Category subdirectories of your perl installation. E.g. "findallmod CGI" will return "CGI::Session"
	   and also "CGI::Session::File" .

       "@found = usesub Module::Category"
	   Uses and returns modules found in the Module/Category subdirectories of your perl installation. E.g. "usesub CGI" will return
	   "CGI::Session", but not "CGI::Session::File" .

       "@found = useall Module::Category"
	   Uses and returns modules found in the Module/Category subdirectories of your perl installation. E.g. "useall CGI" will return
	   "CGI::Session" and also "CGI::Session::File" .

       "ignoresymlinks()"
	   Do not follow symlinks. This function is not exported by default.

       "followsymlinks()"
	   Follow symlinks (default behaviour). This function is not exported by default.
