I've got a few zsh functions that let me type "note" which creates a file named todays date (if it doesn't exist), inserts a timestamp, and opens it in vim. When I exit vim, the notes directory is committed to git then pushed up. This lets me keep my notes directory in sync across machines, and available via web (gitea).

  note () {
   DATE=`date +"%Y%m%d"` 
   TS=`date +"%Y%m%d %H:%M:%S"` 
   FILE=$HOME/Documents/notes/$DATE.txt 
   notegitpull
   echo $TS >> $FILE
   vi $FILE
   notegitpush
  }
  
  notegitpull () {
   pushd $HOME/Documents/notes
   if ping -c 1 git.server &> /dev/null
   then
    git pull
   else
    echo "Offline, not pulling changes"
   fi
   popd
  }
  
  notegitpush () {
   pushd $HOME/Documents/notes
   git pull
   git add \*
   git commit -m "Autocommit due to edit of $FILE"
   if ping -c 1 git.server &> /dev/null
   then
    git push origin main
   else
    echo "Offline, not pushing changes up"
   fi
   popd
  }
