clearSwapOrphan.sh

#!/bin/bash

# if tmux/Vim/OS crashes while I have Vim running I get a swap file sticking around.
# Previously this means I would:
# 1. open Vim in recovery mode for the file
# 2. save the file to a temp file
# 3. diff the temp file and the file I am interested in
# 4. if they are the same, remove the temp file and the swap file
#
# I got tired of this so I wrote this script to ease this a bit. Now you run this script
# with the filename. You still need to run Vim in recovery mode and write out the file, but
# this script will attempt to walk you through some of the steps (and it makes it a little less
# likely that you will accidentally delete the wrong file)

# CURRENT PROBLEM - the trick to finding justSavedFile doesn't work right. Sometimes
# Vim file recovery seems to update the original file and sometimes it doesn't so I
# am not sure how to sort of the file listing to get the actual temp file name...
