bash mkdir ak CP erè sou chemen varyab "pa ka kreye anyè: Pa gen tankou dosye oswa anyè"

Mwen ap eseye otomatize kopye kontni ki soti nan yon chemen varyab (kamera mwen) nan yon chemen pasyèlman-itilizatè-defini (Desktop + dat + evènman) . Pwoblèm lan se ke mkdir ak CP pote plent li di ke anyè a pa ka kreye, men mwen pa konprann poukisa malgre gen DuckDuckGo'd pou plis pase yon èdtan. Kisa mwen fè mal?

echo -n "Enter event name and press [ENTER]: "
read event
sleep 0

day=`date +%Y-%m-%d`
month=`date +%Y-%m`
media="/media/F009-64A5"

source="${media}/PRIVATE/AVCHD/BDMV/STREAM/*"
target="/home/kv/Desktop/$month/$day"\_"$event"

mkdir $target
cp -pr $source $target
