This is string/one today

I'm trying to extract all the lines between 2 strings (including the lines containing the strings)

Something like:

awk '{
if ($1 == "yes") print $2, $4 < infile > outfile1 ;

awk '{ if toupper((substr($1,1,4)) == "ABCD") print $1 }' infile > outfile

Thanks you rule!!!

I'm not certain how that works. I'm new. I want the outfile to retain the case that was in the infile as well.

Thanks again.

I hope this is a basic question.

I have a file with a bunch of strings in each line (and the string number is variable).

I was wondering how sort works.

Does file size and time to sort increase geometrically?
