genericdiary.sh

#!/bin/bash
#*******************************************************#
# Usage: pass in a file name
# Log things into a file in one consistent format       #
# I needed to change IFS else newlines were getting hogged#

# 2009-10-10 09:46 changed rlwrap to use a tmp file
#and vim to edit.
#Also using an ex command to add text to top of file.
