Answer 1

Your question is not very clear, but this is what I think you are looking for:

#!/bin/bash

touch Book1_20190715_1A.gz
touch Book1_20190715A.gz
touch Book2_20190716_1A.gz
touch Book2_20190716A.gz

find . -type f -name "Book*" -print0 | while IFS= read -r -d '' file
do
    # Remove "Book1_"
    tempdirname=${file#*_}
    # Remove ".gz"
    dirname=${tempdirname%\.*}
    echo "$dirname"
    if [[ ! -d "$dirname" ]]
    then
        mkdir "$dirname"
    fi
    /bin/mv "$file" "$dirname"
done

• the find lists all files named Book* and sends that list to a while loop.
• from the filename, extract the directory name using variable expansion. First remove "Book1_", then remove ".gz". This leaves you with the date, and the "_1A" portion, if it is there.
• then create the directory if it does not already exist.
• move the file to the directory.
