break CardDiary export txt file into individual diary txt files with date as title. So that I can import these text files into Evernote.

break_card_diary_export.sh

# 1. Split file by seperator
# Copy tab key as is, not using escape char. It will find “Date” and use it as separator and not delete it.
gcsplit --digits=2  --quiet --prefix=outfile CardDiaryTXT.txt "/      Date/" "{*}"

# 2. Rename file based on content
for filename in *; do
  echo $filename
  mv $filename "$(head -1 $filename | cut -c 8-17) $(echo $filename | cut -c 8-)".txt
done
