This worked to a point - it did not pass in the original lines from the list.txt file - just wrote out the 3 new lines for every line in the file - I need all 4 lines in final output. Sorry but I am new to scripting and thought sed was the way to go.

rcorder
RCORDER(8) BSD System Manager's Manual RCORDER(8)
NAME
rcorder -- print a dependency ordering of interdependent files
SYNOPSIS
rcorder [-k keep] [-s skip] file ...
DESCRIPTION
The rcorder utility is designed to print out a dependency ordering of a set of interdependent files. Typically it is used to find an execu-
tion sequence for a set of shell scripts in which certain files must be executed before others.
Each file passed to rcorder must be annotated with special lines (which look like comments to the shell) which indicate the dependencies the
files have upon certain points in the sequence, known as ``conditions'', and which indicate, for each file, which ``conditions'' may be
expected to be filled by that file.
Within each file, a block containing a series of ``REQUIRE'', ``PROVIDE'', ``BEFORE'' and ``KEYWORD'' lines must appear. The format of the
lines is rigid. Each line must begin with a single '#', followed by a single space, followed by ``PROVIDE:'', ``REQUIRE:'', ``BEFORE:'', or
``KEYWORD:''. No deviation is permitted. Each dependency line is then followed by a series of conditions, separated by whitespace. Multi-
ple ``PROVIDE'', ``REQUIRE'', ``BEFORE'' and ``KEYWORD'' lines may appear, but all such lines must appear in a sequence without any interven-
ing lines, as once a line that does not follow the format is reached, parsing stops.
The options are as follows:
-k Add the specified keyword to the ``keep list''. If any -k option is given, only those files containing the matching keyword are
listed.
-s Add the specified keyword to the ``skip list''. If any -s option is given, files containing the matching keyword are not listed.
An example block follows:
# REQUIRE: networking syslog
# REQUIRE: usr
# PROVIDE: dns nscd
This block states that the file in which it appears depends upon the ``networking'', ``syslog'', and ``usr'' conditions, and provides the
``dns'' and ``nscd'' conditions.
A file may contain zero ``PROVIDE'' lines, in which case it provides no conditions, and may contain zero ``REQUIRE'' lines, in which case it
has no dependencies. There must be at least one file with no dependencies in the set of arguments passed to rcorder in order for it to find
a starting place in the dependency ordering.
DIAGNOSTICS
The rcorder utility may print one of the following error messages and exit with a non-zero status if it encounters an error while processing
the file list.
Requirement %s has no providers, aborting. No file has a ``PROVIDE'' line corresponding to a condition present in a ``REQUIRE'' line in
another file.
Circular dependency on provision %s, aborting. A set of files has a circular dependency which was detected while processing the stated con-
dition.
Circular dependency on file %s, aborting. A set of files has a circular dependency which was detected while processing the stated file.

HISTORY
The rcorder utility first appeared in NetBSD 1.5.

BUGS
The ``REQUIRE'' keyword is misleading: It doesn't describe which daemons have to be running before a script will be started. It describes
which scripts must be placed before it in the dependency ordering. For example, if your script has a ``REQUIRE'' on ``named'', it means the
script must be placed after the ``named'' script in the dependency ordering, not necessarily that it requires named(8) to be started or
enabled.
