Simple program to count and log work time to a time log

logtime.sh

#!/usr/bin/env python3

# Log Time:
#   logtime.sh work 1h30m
# This will add an entry to the file in $logfilename of type "work: 1h30m" under the header for the day
# 
# Usage suggestion:
#   Dependencies: termdown @ https://github.com/trehn/termdown
#   Bash Function:
#       tasktimer(){
#           if [ "$1" == "" ] || [ "$2" == "" ]; then
#               echo "Usage: tasktimer task time"
#               return
#           fi
#           termdown -s -f tinker-toy -T $1 $2 && logtime.sh $1 $2
#       }
#
#   Calling `tasktimer Work 1h30m` will display a terminal countdown for 1h30m and when done will add a work entry to the logfile
