Create directory in date like structure

sachin

I have so many files name like 8888_20210828-000547_9123456789_ABCDEFD_A1099-all.mp3 and wants to create a directory structure 2021/08/28/ABCDEFD/ which I extract from given path and move these files into created directories using shell script

Create a shell script let's say move_files.sh with the following snippet

function filemove() {
    FILE_NAME=$(basename "$1")
    if [[ "$FILE_NAME" =~ ^.+\_[0-9]{8}\-.+_.+_.+-.+\.mp3$ ]]; then
        FILE_DIR=$(echo $1 | awk -F'[_-]' '{print substr($2,1,4) "/" substr($2,5,2) "/" substr($2,7,9) "/" $5 "/";}');
        echo "$FILE_NAME : >> : $FILE_DIR"
        echo "---------------------------";
        echo -e "creating directory:: \e[1;32m $FILE_DIR\e[0m";
        mkdir -p "$FILE_DIR";
        echo -e "moving file:: \e[1;32m $FILE_NAME to $FILE_DIR\e[0m";
        mv -f "$FILE_NAME" "$FILE_DIR";
    else
        echo -e "\e[1;31m ::---------------Invalid file name $FILE_NAME---------------:: \e[0m";
    fi
    echo ""
}

export -f filemove
find ./ -maxdepth 1 -type f -name "*.mp3" -exec bash -c "filemove \"{}\"" \;

Now place this file inside the directory containing mp3 files
and finally form the terminal execute the shell file
./move_files.sh

function filemove() {
    FILE_NAME=$(basename "$1");
    # FILE_PATH=$(dirname "$1");
    FILE_PATH="/home/username/";
    echo -e "\e[1;32mFILE_NAME :: $FILE_NAME :: \e[0m";
    echo -e "\e[1;32mFILE_PATH :: $FILE_PATH :: \e[0m";

    if [[ "$FILE_NAME" =~ ^.+\_[0-9]{8}\-.+_.+_.+-.+\.mp3$ ]]; then
        FILE_DATE=$(echo "$FILE_NAME" | awk -F'[_-]' '{print substr($2,1,4) "-" substr($2,5,2) "-" substr($2,7,9);}');
        FILE_MONTH=$(date -d "$FILE_DATE" +%b);
        FILE_MONTH_FULL=$(date -d "$FILE_DATE" +%B);
        FILE_YEAR=$(date -d "$FILE_DATE" +%Y);
        FILE_YEAR_SHORT=$(date -d "$FILE_DATE" +%y);
        FILE_DAY=$(date -d "$FILE_DATE" +%d);
        FILE_DIR=$FILE_PATH$(echo "$FILE_NAME" | awk -F'[_-]' -v FILE_MONTH_FULL=$FILE_MONTH_FULL '{print substr($2,1,4) "/" FILE_MONTH_FULL "/" substr($2,7,9) "/" $(NF-2) "/";}');
        echo "$FILE_DATE : >> : $FILE_MONTH : >> : $FILE_MONTH_FULL : >> : $FILE_YEAR : >> : $FILE_YEAR_SHORT : >> : $FILE_DAY";
        echo "$FILE_MONTH_FULL : >> : $FILE_DATE : >> : $FILE_NAME : >> : $FILE_DIR";
        echo "---------------------------";
        echo -e "creating directory:: \e[1;32m $FILE_DIR\e[0m";
        mkdir -p "$FILE_DIR";
        echo -e "moving file:: \e[1;32m $1 to $FILE_DIR\e[0m";
        mv -f "$1" "$FILE_DIR";
    else
        echo -e "\e[1;31m ::---------------Invalid file name $FILE_NAME---------------:: \e[0m";
    fi
    echo ""
}

export -f filemove
find /home/username/ -maxdepth 3 -type f -name "*.mp3" -exec bash -c "filemove \"{}\"" \;

This will generate path /home/username/2021/September/24/ABCDEFD/
