How do you expect the solutions provided to work on files that have nothing to do with your sample presented in the first place? In your recent file, there's NO REF*D9*1001 present, NOR do I find an NM1*85 within an REF*D9 defined range. And your expected output from post #10 definitely can't be produced with that input file.
Any proposal given relies on above data to be existent in the file; no surprise you get an empty output.
Please use the proposals and adapt to your needs.

git-symbolic-ref
GIT-SYMBOLIC-REF(1) Git Manual GIT-SYMBOLIC-REF(1)
NAME
git-symbolic-ref - Read and modify symbolic refs
SYNOPSIS
git symbolic-ref [-m <reason>] <name> <ref>
git symbolic-ref [-q] [--short] <name>
DESCRIPTION
Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory.
Typically you would give HEAD as the <name> argument to see which branch your working tree is on.
Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>.
A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose
contents is ref: refs/heads/master.
OPTIONS
-q, --quiet
Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently.
--short
When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.
-m
Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.
NOTES
In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf
refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are
not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default.
git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is
not a symbolic ref, or 128 if another error occurs.
