i stumbled upon a great idea: store quick notes in a private mailbox. it's a very smart solution especially because the notes are searchable and available from anywhere. the concept is very easy to implement therefore it's adjustable to various toolchains.

pbrisbin provides a command-line+mutt+GMail solution. i did a few modifications to accomplish a GMail free and 'offline-working' version. i replaced mutt by msmtpQ a wrapper for msmtp and GMail by a procmail filter. in addition i made the subject prefix optional and added a custom e-mail header to tag the note.

#shell script
function noteit() {

  local message subject="$*" mail="YOUR@EMAIL.com"

  [[ -z "$subject" ]] && { echo 'no subject.'; return 1; }

  echo -e "^D to save, ^C to cancel\nNote:\n"

  message="$(cat)"

  [[ -z "$message" ]] && { echo 'no message.'; return 1; }

  echo "From: $mail\nTo: $mail\nSubject: $subject\nX-Tag: note\n\n$message" \
       |/usr/local/bin/msmtpQ $mail &> /dev/null

  [[ $? -ne 0 ]] && { echo "failed."; return 1; }
}

#procmail filter
