archive files based on creation date

.bashrc

archive() {
    if [ ! -d "$1" ]; then echo Missing base; return 1; fi
    local BASE=$1
    for f in "${@:2:$#-1}"; do
        if [ -d "$f" ]; then continue; fi;
        local DATE=`date -r "$f" "+%Y-%m-%d"`
        local YEAR=`date -r "$f" "+%Y"`
        local TARGET_DIR="$BASE/$YEAR/$DATE"
        mkdir -p $TARGET_DIR
        echo cp -iv "$f" "$TARGET_DIR/"
        cp -iv "$f" "$TARGET_DIR/"
    done
}
export -f archive

# $ yes n | archive ~/Desktop/msc/media /Volumes/H4N_SD/STEREO/**/*
# $ archive ~/archive myfile.wav
# > myfile.wav -> ~/archive/2020/2020-10-15/myfile.wav
# # $ archive ~/archive *

Looks like it's not working with files that have spaces in the names..
