Bash Script to Rename Files then Sync Files (router configs) from TFTP to Git

I created a script so when a cisco router config is saved its sent to a TFTP server, i would like to rename the config (as cisco appends the time) from
PHC-16JUB-SW01.txt-Jul-20-2023-04-13-57.744-UTC-30
to
PHC-16JUB-SW01.txt
I am doing this so when i commit to GIT its not a "unique" file.

Once the file has been renamed, its then sent to GIT for auditing/backup

im not proficient in coding, this is my best try from all the SO and github scripts out there.

#!/bin/bash

file_closed() {
FILENAME="echo $FILE | grep -o '^.*\.txt'"
OUTPUT=$(eval $FILENAME)
        mv "$DIRECTORY/$FILE" "$DIRECTORY/$OUTPUT"
}

git_commit() {
DATE_FMT=$(date +"%Y-%m-%d %H:%M:%S")
        cd /var/lib/tftpboot/$DIRECTORY
        git add .
        git commit -m "Config updated ($DATE_FMT)"
        git push

}

inotifywait -q -m -r -e close_write $1 | while read DIRECTORY EVENT FILE; do
    case $EVENT in
        CLOSE*)
                file_closed "$DIRECTORY" "$FILE"
                git_commit
            ;;
    esac
done

Executing the script will commit the changes to GIT bit also get stuck in a loop trying to "mv" other files..

thanks to Kurtis Rader suggestion.. i ran the code through ChatGPT and got the below code, which works flawlessly.

#!/bin/bash

file_closed() {
    local FILE="$1"
    local FILENAME="${FILE%%.txt-*}.txt"
    mv "$DIRECTORY/$FILE" "$DIRECTORY/$FILENAME"
}

git_commit() {
    local DIRECTORY="$1"
    local DATE_FMT=$(date +"%Y-%m-%d %H:%M:%S")
    cd "/var/lib/tftpboot/$DIRECTORY"
    git add .
    git commit -m "Config updated ($DATE_FMT)"
    git push
}

while read -r DIRECTORY EVENT FILE; do
    case $EVENT in
        CLOSE*)
            file_closed "$FILE"
            git_commit "$DIRECTORY"
            ;;
    esac
done < <(inotifywait -q -m -e close_write --format '%w %e %f' "$1")

In this corrected version, we pass the DIRECTORY and FILE variables correctly to the functions. We use parameter expansion to extract the base filename without the timestamp in the file_closed function. The git_commit function now accepts the DIRECTORY as an argument. The inotifywait command is used with the --format option to get the necessary information about the event.
