# designed to quickly move all mah oreilly downloads to a folder where i 
# can sort them

# assumptions:
#     the only epubs are from o'reilly
#     i download several formats for each book (pdf, epub, mobi)
#     my main ebook library is organised by topic/.../title/title.*

# after i run this, i open the target directory and filter the files into
# the main library from there.

targetdir="$1"

if [ ! -d $targetdir ]; then
    if [ -e $targetdir ]; then
        echo "[!] please pass in either the directory to create or a directory"
        exit 1
    fi

    mkdir $targetdir
fi

for book in $(ls *.epub)
do
    if [ -z "$book" ]; then 
        continue
    fi
    title="$(echo ${book##/*} | sed -e 's/\(..*\)\..*/\1/')"
    echo "[+] processing $title"
    mkdir $title
    printf "\t"
    mv -v ${title}.* ${title}/
    mv $title/ $targetdir/
