That is sick stuff vgersh99...unfortunately i forgot to tell you that my input.txt is a lot longer than 3 lines, say it's 6 lines, but I still don't want to overwrite the HHH.
but I still want the "HHH". So this is more like a INSERT and not a overwrite. My bad.

hey guys, actually i found a suggestion that solves one of my two problems.
I think my question is set. Thanks for looking everyone! Thanks vgersh99 for the sick one liner.
there's no limitation/hard-wiring on the number of lines to be inserted - everythig is driven by the content in your input.txt file. It should work for ANY number of lines.
I have a file which contains blocks of text - each block is a multi-lines text delimited by blank lines eg.
<blank line>
several lines of text
...
pattern found on this line
several more lines of text
...
<blank line>
How do you delete the block of text (including the blank lines) when... (17 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
