Bash is symlinking to working directory instead of specified directory

Bash is symlinking to working directory instead of specified directory

I am working on a bash script that I am working on for a universal Linux
dotfile install script. I am attempting to get the symlinking working but
I have been bashing (no pun intended) my head against the wall trying to
figure out why the symlinks will not work and the copying will not work. I
currently have this separated into multiple files so I don't have if
statements three miles long.
ultimate-install.sh
#! /bin/bash
#
# The ultimate install script for all dotfiles.
if [[ -z "$1" ]]; then
echo "Please specify the directory where all of you dotfiles are
located."
exit 1
fi
# Makes sure that the directory does NOT have a trailing slash!
if [[ ${1:(-1)} == "/" ]]; then
DOTFILE_DIR=${1:0:${#1} - 1}
else
DOTFILE_DIR="$1"
fi
# TODO: Clean this mess up and make it more concise.
if [[ -z "$2" ]]; then
if [[ ! -d $HOME/.config/old_dotfiles ]]; then
mkdir "$HOME/.config/old_dotfiles"
fi
BACKUP_DIR="$HOME/.config/old_dotfiles"
else
if [[ -d "$2" ]]; then
BACKUP_DIR="$2"
else
mkdir "$2"
BACKUP_DIR="$2"
fi
fi
read DECISION
if [ $DECISION == "N" -o $DECISION == "n" ]; then
echo "Aborting installation!"
exit
fi
read DECISION
echo
if [ $DECISION == "N" -o $DECISION == "n" ]; then
source src/no-prompts.sh "$DOTFILE_DIR" "$BACKUP_DIR"
else
source src/prompts.sh "$DOTFILE_DIR" "$BACKUP_DIR"
fi
echo "Installation complete. Old dotfiles are backed up to $BACKUP_DIR."

if [ ${FILE_NAME:0:1} == "." ]; then
rm -rf "$TEST_DIR/$FILE_NAME"
ln -sn "$FILE_PATH $TEST_DIR/$FILE_NAME"
else
FILE_NAME="."$FILE_NAME
rm -rf "$TEST_DIR/$FILE_NAME"
ln -sn "$FILE_PATH $TEST_DIR/$FILE_NAME"

# TODO: implement a check for file type and deal with unknown files.
for FILE in $DOTFILE_DIR/*; do
cp $FILE $BACKUP_DIR
prompt_install $FILE
done
The above is trimmed for long echo statements that do a lot of explaining.
The basic idea of this script is to take as many as two arguments (the
dotfile directory to install and if specified, the custom backup
directory, $1 and $2 respectively). The script should then copy all of the
files in the target directory to BACKUP_DIR and symlink all of the
dotfiles in the DOTFILE_DIR to TEST_DIR. (TEST_DIR will be $HOME in the
production scripts.) Great in theory, right?
The complication comes when I run the script. None of the files are copied
or symlinked as they should be. Instead, I end up with NO copy (probably
due to the same issue as the symlink not working) and a broken symlink in
the current directory.
One last piece of information. I am executing the file from the directory
that contains ultimate-install.sh
(/home/daniel/Projects/Git-Repos/Ultimate-Dotfile-Install-Scripts).
So where did I go wrong?
PS Please don't comment on the TODOs. :)
