The simplest way, if your input file is at /folder/somefile.txt,


# Script lines.txt
# Read input file into a string variable.
var str input ; cat "/folder/somefile.txt" > $input
# Remove everything before "hello world2".
stex "]^hello world2^" $input > null
# Remove everything after "hello world5\n".
stex "^hello world5\n^[" $input > null
# $input now has only the desired portion. Print it.
echo $input




Script is in biterscripting ( http://www.biterscripting.com ). To try, save the script as /Scripts/lines.txt, start biterscripting, enter the following command.


script lines.txt


Script can also be called directly from another program, or another shell, as,


/biterScripting/biterScripting.exe lines.txt


Make sure you use the correct file location instead of /folder/somefile.txt. Note the double quotes, ^, [ and ] in the string extractor command syntax. Feel free to translate the script to any other language.
