I have a bash script to commit untracked files, which looks like:

#!/bin/bash

set -e
# https://stackoverflow.com/a/5238537/6796500
files=$(git status --porcelain | sed s/^...//)

if [[ $files == "" ]]; then
    echo "No files changed."
else
    for file in $files
    do
        git add $file
        git commit -m ":white_check_mark: $file"
    done
    git push
fi

The files array looks like ['347. Top K Frequent Elements.md', '206. Reverse Linked List.md']. when I echo $file, I got 347. , Top etc., that wasn't I wanted, I want to get 347. Top K Frequent Elements.md, 206. Reverse Linked List.md.

Can you guys help me to get the desired filename?
