Dang, true. Didn't catch that.
I think sometime I had set cron to run a script every day at a certain time and bypassed every other day with a simple .txt file.
Top of my script was a simple if-clause, when alternate-day.txt is found, it will be removed and the script runs. If no .txt is found it will be created and the script exits. A bit lame, but it worked and was quick :)
