Fix a Script That Breaks on Spaces

easy 10 XP ~6 minHands-on lab

/home/student/bin/archive-csv.sh DIR moves every .csv file in DIR into DIR/archive/ and prints archived N. It works in tests, but in production it mangles files such as Q3 sales.csv and folders such as /data/team reports.

Task

Fix archive-csv.sh so that it:

works when DIR contains spaces
moves every .csv file in DIR (not in subfolders), whatever characters its name contains, including spaces and [ ]
creates DIR/archive/ if it is missing
prints archived N with the right count (archived 0 when there are none)
does not touch other files
