move contents from one file to another based on line number or content
I want a script that will move everything beyond a certain line number or beyond a certain content word into another file.
For example, if file A has this:
first line
second line
third line
forth line
fifth line
sixth line
I want to run a script that will move everything beyond the third line to the END of file B, OR it would be even better if the script will move everything beyond the specific words "third line" into file B. That way I could just put in some random characters where I want the cutoff to be and never have to worry about the line number. I am not very good at scripting and do not know where to start. Any help would be greatly appreciated.

shtool-move
SHTOOL-MOVE.TMP(1) GNU Portable Shell Tool SHTOOL-MOVE.TMP(1)
NAME
shtool-move - GNU shtool enhanced mv(1) replacement
SYNOPSIS
shtool move [-v|--verbose] [-t|--trace] [-e|--expand] [-p|--preserve] src-file dst-file
DESCRIPTION
This is a mv(1) style command enhanced with the ability to rename multiple files in a single operation and the ability to detect and not
touch existing equal destinations files, thus preserving timestamps.
OPTIONS
The following command line options are available.
-v, --verbose
Display some processing information.
-t, --trace
Enable the output of the essential shell commands which are executed.
-e, --expand
Expand asterisk in src to be used as ""%"n" (where n is 1,2,...) in dst-file. This is useful for renaming multiple files at once.
-p, --preserve
Detect src-file and dst-file having equal content and not touch existing destination files, thus perserving timestamps. This is useful
for applications that monitor timestamps, i.e. suppress make(1L) repeating actions for unchanged files.
EXAMPLE
# shell script
shtool move -v -e '*.txt' %1.asc
# Makefile
scanner.c: scanner.l
lex scanner.l
shtool move -t -p lex.yy.c scanner.c
HISTORY
The GNU shtool move command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1999 for GNU shtool.
SEE ALSO
shtool(1), mv(1), make(1).
