Script for opening a task file for today and the most recent task file in vim.

open_task_files.sh

#! /bin/bash

# Inspired by Jamis Buck's blog entry:
# http://weblog.jamisbuck.org/2015/3/17/task-tracking-for-neurochemical-brains.html

# Go to tasks folder and open (or create) today's task file
# and the previous task file in vim.

cd ~/tasks
TODAY="tasks_`date '+%Y_%m_%d'`.txt"

# Get the last two task files by date.
arr=( $(ls -1 tasks_* | sort -r | head -n2) )

# Remove the first or last element in the array depending on the
# existence of today's task file.
if [ ${#arr[@]} -gt 1 ]; then
  if [ $TODAY = ${arr[0]} ]; then
    unset arr[0]
  else
    unset arr[1]
  fi
fi

# Use -n to open vim without creating swap files.
vim -n $TODAY ${arr[@]}
