perl -e 'print "Like";' -e 'print " This?"' > test.txt

Don't think you can use the -n loop to do this - or have i misunderstood?

Using -n would be like
perl -n -e 'code' somefile

Interpreted as

while (<>) {
# code
}

Tested this and it works
perl -n -e '!EOF' test.sh test2.sh > othertest.sh

EDIT Think I misunderstood what he's trying to do!!

grep -A 100 start file | grep -B 100 end | grep -v start | grep -v end

Where "file" is the target file name, "start" is the opening word, "end" is the closing word, 100 is maximum nuber of lines between "start" and "end".
Extremely terrible, but maybe it encourages someone to post something more sophisticated

What do you have so far?

What criteria do you want to use to decide which parts of the file to select?

you can use

sed -n '/FIRST_WORD/,/SECOND_WORD/p' big_file >reqd_file

note: This will also contain the lines containing the FIRST_WORD and the SECOND_WORD.

Matthew,

for ex:

today, my "key" are in the line 244

tomorrow, my same "key" can be 230 or the other line
