Sort your download directory into weeks

weekify.sh

#! /bin/bash

WEEK=$(/bin/date +%V)

if [ ! -d $HOME/Downloads/week-$WEEK ]; then
    mkdir $HOME/Downloads/week-$WEEK
fi

downloadedFiles=($(find $HOME/Downloads -depth 1))

fileCount=${#downloadedFiles[@]}

for (( i=0; i<${fileCount}; i++ ));
do
  if [[ ! "${downloadedFiles[$i]}" =~ 'week-' ]]; then
    if [[ ! "${downloadedFiles[$i]}" =~ 'crdownload' ]]; then
      mv "${downloadedFiles[$i]}" "$HOME/Downloads/week-$WEEK/"
    fi
  fi
done

Fixed bug where not done downloads would be moved if another file finished downloaded.
