How to break/split a long string in linux using AWK command

Question

We have a directory consisting so many files/string like below

1234_20190817-194937_1111111111_NAME_ABC-all.mp3
111_20180312-194937_222222_FILENAME2_xyz-all.mp3

and need to break and make it different folders like below

> 2019/08/17/NAME

> 2018/03/12/FILENAME2

so need to write shell scripting using AWK command

Answer 1

function filemove() {
FILE_NAME=$(basename "$1")
if [[ "$FILE_NAME" =~ ^.+\_[0-9]{8}\-.+_.+_.+-.+\.mp3$ ]]; then

FILE_DIR=$(echo $1 | awk -F'[_-]' '{print "/FOLDER/" 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 /FOLDER/ -maxdepth 1 -type f -name "*.mp3" -exec bash -c "filemove \"{}\"" \;
