thanks Balaji that works.

thanks Corona, i see what you are saying i should have been more specific with my sample file. it actually looks like this.

Code:
cat file ... how r u 
whats up  ... Hello world how r u whats up .... .... 
how r u 
whats up

the only unique pattern is "Hello World", the 2 lines after that repeated across the file. so ideally i have to search for Hello world and the 2 lines after that and insert # at the begining of each line. this i was not able to achieve with sed.

VIEWPERL(1)							   User Commands						       VIEWPERL(1)

NAME

       viewperl - quickly view syntax highlighted Perl code

SYNOPSIS

       viewperl [OPTION]... FILE...

DESCRIPTION

       View a Perl source code file, syntax highlighted.

       -c, --code=CODE
	      view CODE, syntax highlighted

       -l, --lines
	      display line numbers

       -L, --no-lines
	      supress display of line numbers (default)

       -m, --module=FILE
	      consider FILE the name of a module, not a file name

       -n, --name
	      display the name of each file (default)

       -N, --no-name
	      supress display of file names (implied by --no-reset)

       -p, --pod
	      display inline POD documentation (default)

       -P, --no-pod
	      hide POD documentation (line numbers still increment)

       -r, --reset
	      reset formatting and line numbers each file (default)

       -R, --no-reset
	      supress resetting of formatting and line numbers

       -s, --shift=WIDTH
	      set tab width (default is 4)

       -t, --tabs
	      translate tabs into spaces (default)

       -T, --no-tabs
	      supress translating of tabs into spaces

       --help display this help and exit

       Note that module names should be given as they would appear after a Perl `use' or `require' statement.  `Getopt::Long', for example.

       Each string given using -c is considered a different file, so line number and formatting resets will apply.
