I wouldn't test for filenames containing spaces, tabs, or newlines, I'd just write code that works even if they are present. (And if I found users creating filenames containing whitespace characters, I'd ban them from using my system! Smilie Unfortunately, there need to be exceptions for some things like .mp3 and .mp4 files with spaces in the titles of songs and movies, but most users creating filenames containing spaces are just trying to create problems for inexperienced programmers.)

Stop trying to create lists and then trying to process the list. Process filenames one at a time. And, learn to use shell built-ins instead of pipelines of awk, grep, and ls commands. Try something more like:
Code:
#!/bin/bash
# Assume that we are starting in a directory with a filename suffix ".git".
# Get related non-".git" directory name.
FOLDER_NAME=${PWD##*/}		# Extract last component of current working directory
FOLDER_NAME=${FOLDER_NAME%.git}	# Throw away ".git".

printf 'DEBUG: VAR FOLDER_NAME=%s\n' "$FOLDER_NAME"

# Process the files in the non-".git" directory...
for FILE in ../"$FOLDER_NAME"/*
do	# Skip files that are not regular files...
	[ ! -f "$FILE" ] && continue

	# Do whatever you want with the regular file from ../"$FOLDER_NAME"...
	printf 'DEBUG: VAR FILE="%s"\n' "$FILE"
	printf 'another file inside the FOR loop\n:'	# Should ":" be before newline?
done

If you don't understand how something in the above works, try running it with:
Code:
bash -xv script_name

and watch how bash processes each command in the script. If you still don't understand, ask questions... We're here to help you learn.

GIT-SH-SETUP(1) 						    Git Manual							   GIT-SH-SETUP(1)

NAME
git-sh-setup - Common git shell script setup code SYNOPSIS
. "$(git --exec-path)/git-sh-setup" DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish scripts and/or are writing new ones. The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal git directories and a few helper shell functions. Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage() shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not). The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment. FUNCTIONS
die exit after emitting the supplied error message to the standard error stream. usage die with the usage message. set_reflog_action set the message that will be recorded to describe the end-user action in the reflog, when the script updates a ref. git_editor runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified and the terminal is dumb. is_bare_repository outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated working tree). cd_to_toplevel runs chdir to the toplevel of the working tree. require_work_tree checks if the repository is a bare repository, and dies if so. Used by scripts that require working tree (e.g. checkout). get_author_ident_from_commit outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
